brain plasticity
Opis:
Cerebral plasticity plays an important role in learning and in neurological recovery after nervous lesions. However, in certain nervous diseases that same plasticity may lead to nervous system malfunction. Nowadays there are new methods that seem to be able to modulate nervous system function, namely transcranial magnetic stimulation and transcranial direct current stimulation. By use of these methods it may be possible, for example, to transiently improve learning and other mental abilities in normal volunteers or to treat symptoms of maladaptive brain plasticity in various neurological and psychiatric conditions. In this article we review the history, the fundamentals and the most important uses of these techniques.

Opis:
Emigration is a chronic structural process of the Portuguese society. The discussion and key arguments raised in this chapter are mainly focused on data from a research project on Portuguese skilled emigration. Based on the outcomes of the BRADRAMO2 on-line survey to 1011 highly skilled emigrants it can be suggested that recent phenomena in general, and the crisis that began around 2008 in particular, profoundly transformed the patterns of Portuguese emigration. Nowadays, the country faces a brain drain dynamic that is dramatically altering the profiles of national emigrants, emigration destinations, self-identity, and the strategies of those who leave the country. Academic mobility, mainly that promoted by the European Union (through grants from the Erasmus Program), created and fostered mobility flows that reinforced a latent mobility phenomenon. Once engaged in academic mobility programs, Portuguese higher education students tend to stay in the country of destination or, upon returning temporarily to Portugal, to evince a very strong predisposition to move to a country of the European Union. The profile of Portuguese high-skilled emigrants reveals a trend towards a permanent and a long-term (as opposed to a temporary or transitory) mobility, an insertion in the primary segment of the labor market of the destination countries, a predominance of professionals connected to the academic/scientific system and to professions requiring high skills, and a latent mobility (aft er a period of study in the country of destination) rather than direct mobility flows (after having entered in the employment system of the sending country).

Introduction and objectives. A number of preclinical evaluations of stroke treatment with herbal medicine (HM) have been reported. The aim of the current review was to highlight the pathophysiology of stroke and review the pre-clinically identified molecular mechanisms of HM treatment. Materials and method. Only 32 articles published in the English language were accessible on Google scholar describing the treatment and mechanistic processes of HM in animal models of stroke, as well as human clinical trials, and were reviewed in this study. Results and discussion. Suboptimal Na+/K+ ATPases pump activity, actions of microglia cytokines that increase the level intracellular adhesion molecules-1 (ICAM-1) which promote WBC extravasation with associated increased in matrix metalloproteinase (MMP) activity (digest basement-membranes), explains edema and apoptosis/inflammation. Altered conductivity in injured neurons with compensatory increase in glutamate release that overwhelms the regulatory glial glutamate transporter 1, and thus peaks the level of glutamate to an excitotoxin leve, promotes neuronal death. Glutamate activity on NMDAR promotes oxidative stress, lipid peroxidation and release/influx of Ca2+ that causes apoptosis. The molecular targets involved in the treatment for stroke by HM promote anti-apoptotic/anti-inflammation, anti-oxidation, angiogenesis, neurogenesis, anticoagulation/fibrinolysis effects and optimal metabolism. Different HM promotes the activities of tissue plasminogen activator, haemeoxygenase 1, Neutrin-1, brain derived neurotropic factor (BDNF) and mitogen-activated protein kinase (MAPK). Conclusion. The pathophysiology of stroke and the preclinical targets on which HM act to ameliorate them were identified which could serve as a focus for research on the development of effective treatment for stroke.

Opis:
The neuropsychology of creativity is recently understood as a subdiscipline developing on the borderline of being a: (1) medical neuroscience - using clinical and experimental neuroanatomical, neurophysiological, neurobiological, neurosurgical, neurological, neuropsychiatric methods and approaches and (2) social neuroscience - using social psychology and neuropsychology, social linguistics and neurocultural studies to help disabled people. The subject of research into the neuropsychology of creativity is the relationship between creativity and the functioning of the brain (structures and neuronal connections) and the self using the individual, social and cultural mind and modelling these behaviors in relation to the biological organism and the social and cultural environment itself. Neuropsychological research of creativity is directed mainly to discover the brain mechanisms of creativity, to form the theoretical models, to elaborate the methods of diagnosis and therapy of artists with brain damage. A promising model that allows for a better understanding of the creation process, and therefore one offering better assistance to individuals who have never developed or have lost the ability to create due to brain damage, is the microgenetic approach that will be discussed in this article. To introduce the reader to these issues, a case study of an artist with brain damage is presented. It illustrates the importance of performing a syndrome analysis, supported by the neurophysiological studies (neuroimaging studies of the brain, quantitative electroencephalography (qEEG), event-related potentials (ERPs) and sLorette tomography) with the use of neuromarkers to avoid a false diagnosis. It also shows the possibilities of art therapy in the process of rebuilding the creative abilities lost as a result of brain damage, and thus the rebuilding of one's individual, social and cultural Self. However, something that is also important for artists, selected works, especially the most characteristic and significant ones, are also achieving critical recognition. It even happens that they become a part of the world's cultural heritage, are displayed at various exhibitions and are even bought to be hung in the collections of galleries acrosss the world, like in the case of the artist presented in these paper.

Opis:
Poly(ADP-ribose) polymerase (PARP) is a conserved enzyme involved in the regulation of DNA repair and genome stability. The role of PARP during aging is not well known. In this study PARP activity was investigated in nuclear fractions from hippocampus, cerebellum, and cerebral cortex of adult (4 months), old adult (14 months) and aged (24-27 months) rats. Concomitantly, the free radical evoked lipid peroxidation was estimated as thiobarbituric acid reactive substances (TBARS). The specific activity of PARP in adult brain was about 25, 21 and 16 pmol/mg protein per min in hippocampus, cerebellum and cerebral cortex, respectively. The enzyme activity was higher in all investigated parts of the brain of old adults. In aged animals PARP activity was lower in hippocampus by about 50%, and was unchanged in cerebral cortex and in cerebellum comparing to adult rats. The concentration of TBARS was the same in all parts of the brain and remained unchanged during aging. There is no direct correlation between PARP activity and free radical evoked lipid peroxidation during brain aging. The lowered enzyme activity in aged hippocampus may decrease DNA repair capacity which subsequently may be responsible for the higher vulnerability of hippocampal neurons to different toxic insults.

Opis:
Introduction. During puberty, the young body undergoes transformation not only within the reproductive and hormonal systems, but also significant changes in the central nervous system (CNS). Matured neural connections improve the integration of distant brain regions, the plasticity of neurons increases, and thus specialization of the brain occurs in the performance of specific tasks. During these transformations, both neurons and the accompanying neuroglia are sensitive to all toxic factors, among which ethanol occupies a special place. It causes an increase in the activity of glial cells, which by directing pro-inflammatory cytokines directly contribute to the death of apoptotic neurons. A long-lasting and irreversible impairment of brain function, especially in the hippocampus occurs as a result of alcohol abuse during the period of development. Aim. This paper presents an overview of current knowledge about the effects of alcohol on neuroglia in the developing brain and in adults. Materials and methods. The literature review of the following databases has been conducted: EBSCO, PubMed, Science Direct, Springer Link. Conclusions. The results of alcohol research have shown that it affects the neurotransmission and fluidity of cell membranes, changing the activity of neurons. By binding to GABA receptor (GABA) and N-methyl-D-aspartate receptors (NMDA receptor for glutamate), ethanol suppresses brain function. In addition to increased sensitivity and susceptibility to the addictive effects of ethanol, the neurogeneration activity is intensified followed by the induction and release of pro-inflammatory cytokines, which in the first stage disrupt the cortical function hindering logical thinking and disrupting the limbic system, directly affecting the memory and learning processes. Next, the cerebellum is attacked, which results in the impairment of balance and motor coordination, and consequently acts on the brain stem, directly affecting the respiratory and circulatory control centers.

Opis:
‘The brain is not a place to store memory’ is the famous thesis that was proposed in “Matter and Memory” chapter 2. From there, Bergson demonstrates that memory exists from the brain independently and the quality of memory is non-material and spiritual. According to Bergson, the brain is only an instrument of memory power and memory is spirit and reality that exist from the brain independently. He negated the theory of location of memory and argued the brain and memory from the whole theory of the brain. Well, what is the meaning of his memory and brain theory from the view point of contemporary brain physiology? Are his memory and brain theory fit for contemporary brain physiology? I want to conclude the confrontation between the theory of Bergson and contemporary brain physiology comparing the theories of Bergson and Wilder Penfield (1891-1979) who was the most famous brain surgeon in Canada. The conclusion is that dualism is amended to monism by the quantum theory, the idea of Biocosmological Association and my philosophy ‘Philosophy of Nothingness and Love’ and that the new road of physiology and medicine is opened.

Biochem. 1989, 183, 139-143). Basing on these data it can be presumed that PKA activity increases, but the levels of CK2 and CK1 decrease during chick embryo development.

Opis:
In recentyears, we have witnessed an intensive development of many New areas of research and scientific research, to chich undoubtedly belong those referred to as neuroscience, thatis, focusing on the study of the human brain and nervous system. In my speech I would like to review opinions on possibile attempts to relate brain research results to school conditions as well as teaching and learning concepts. The following concepts will be analyzed: neurodidactics, neuropedagogy and neuroeducation. I will also present my proposition of under standing neuroeducation as anactivity focused on: 1) development of cognitive processes of learners and awareness of the existence of these processes; 2) education of learning process management, 3) getting to know and better understanding of the learning process through the prism of functioning: brain, mind and education. Neuroeducation understood in this way is, in my opinion, a chance for a new perspective of in sight into learning processes and, in the longer term, teaching. It can therefore be addressed to pupils and students, but also to teachers. The direction of neuroeducation thought outlined in the article, in my opinion, fits in with the thinking about constructivist variation, objectivist today (according to Dorota Klus-Stańska) paradigm of neurodidactics.

Background. Local synchronization of the electrical activity of the cerebral cortex at rest with eyes open in persons with different levels of divergent thinking were studied. Material and methods. 95 men and 98 women aged 18-21 with different levels of divergent thinking were studied. The power of the EEG at rest with eyes closed and open was analyzed. Results. There were established differences in the extent of the depression depth, as well as in the activation of the EEG alpha rhythm, which is related to gender and level of productivity. Women have a greater depth of alpha rhythm depression than men. In subjects with high and medium levels of divergent thinking, alpha-rhythm depression was of a generalized nature, and in subjects with low levels of divergent thinking – local and topographically non-specific. Conclusions. These results indicate that the EEG response of readiness to perceive stimuli, which provides either very high or very low productivity of divergent thinking, is manifested in the dynamics of the biopotential power in the EEG alpha range.

Opis:
Sprostanie problemom, które wynikają z braku wykwalifikowanej siły roboczej, stanowić będzie w przyszłości istotne wyzwanie dla rozwoju regionalnego. Problem dotyczy w szczególności wysoko wykwalifikowanych pracowników, traktowanych jako nośniki wiedzy, których absencja może negatywnie wpływać na społeczno-gospodarczy rozwój regionalny. W powyższym kontekście uwzględnienie migracji osób wysoko wykwalifikowanych powinno stać się częścią regionalnej strategii przeciwdziałania zjawisku utraty wykwalifikowanej siły roboczej, przy czym w obliczu mobilności europejskiej na szczególną uwagę zasługuje problem transferu wiedzy. Swoboda przepływu zasobów pracy natrafia niejednokrotnie na przeszkody praktyczne, takie jak: brak dostępu do poszczególnych zawodów, regionalnych rynków pracy i społeczności regionalnych. Obok działań zmierzających do uznawania kwalifikacji zawodowych regiony powinny wypracować koncepcje, zmierzające do pełnego wykorzystania potencjału zawodowego migrantów i ich umiejętności, a następnie do całkowitego wchłonięcia ich wiedzy. W związku z powyższym głównym celem niniejszego artykułu jest przedstawienie wpływu wiedzy posiadanej przez migrantów na rozwój regionów pochodzenia i regionów docelowych oraz prezentacja dwóch inicjatyw wspierających rozwój regionalny, tj. koncepcji inkluzji migrantów oraz zwiększania zdolności absorpcyjnej regionów. Są to instrumenty, które pozwolą na uniknięcie negatywnych konsekwencji zjawisk migracyjnych typu: brain drain i brain waste, a jednocześnie pozwolą na wykorzystanie wiedzy w wyniku brain gain i brain exchange. W końcowej części artykułu przedstawiono sieci migracyjne, postrzegane jako instrument służący zwiększaniu absorpcji wiedzy oraz wspierający integrację społeczną.
One of the key rights of each European citizen stated in the Lisbon Treaty is the freedom to move within Europe. Especially, in times of increasing intra- and inter-European labour mobility, this right should be the spotlight of regional, national and EU agenda. But in reality, the freedom of movement underlies practical obstacles such as an access to particular occupations and regional labour markets, which is bound to (a) the official recognition of professional qualifications, differing in each member state as well as (b) language skills. These and further factors hinder (1) labour migrants to make full use of their skill potential and (2) regions to completely absorb their knowledge. Thus, metaphorically speaking, the knowledge gets lost and wasted between the home and target emigration regions. Hence, this article aims at presenting knowledge effect on the home and target regions and discusses possible regional structures fostering inclusion and absorption capacity to avoid brain drain and brain waste, but empowers brain gain and brain exchange as positive knowledge effects. The final part presents regional actors' networks and inter-regional social networks (migration networks) as possible instruments to build regional structures for better regional social inclusion and knowledge absorption and as pipelines for knowledge spillover.

This article aims at studying the mobility of Polish highly skilled female workers who live in Italy, and at analysing their integration into the society and the labour market, with particular reference to the problem of brain waste. Using the biographical approach we analyse the reasons for migration from a transnational perspective. We highlight the active role of the Polish social network that explains the high presence of Polish people in Rome, determined by more than purely economic reasons. Eventually, in the light of brain waste, we try to understand the role of the academic and career paths by looking into possible problems related to the adequate utilisation of professional competences and acknowledgement of the level of educational attainment.

Opis:
Introduction: Blood brain barrier and multidrug resistance phenomenon are subjects of many investigations. Mainly, because of their functions in protecting the central nervous system (CNS) by blocking the delivery of toxic substances to the brain. This special function has some disadvantages, like drug delivery to the brain in neurodegenerative diseases. Objective: The aim of this study was to examine how natural and synthetic substances affect the expression levels of genes (Mdr1a, Mdr1b, Mrp1, Mrp2, Oatp1a4, Oatp1a5 and Oatp1c1) that encode transporters in the blood-brain barrier. Methods: cDNA was synthesized from total RNA isolated from rat hippocampus. The expression level of genes was determined using real-time PCR (RT-PCR) method. Results: Our findings showed that verapamil, as a synthetic substance, caused the greatest reduction of mRNA level of genes studied. The standardized extract of Curcuma longa reduced the expression level for Mrp1 and Mrp2, whereas the increase of mRNA level was observed for Mdr1b, Oatp1a5 and Oatp1c1. Conclusions: These results suggests that herbal extracts may play an important role in overcoming the blood brain barrier during pharmacotherapy

Opis:
Potassium channels are the most widely distributed class of ion channels. These channels are transmembrane proteins known to play important roles in both normal and pathophysiological functions in all cell types. Various potassium channels are recognised as potential therapeutic targets in the treatment of Parkinson's disease, Alzheimer's disease, brain/spinal cord ischaemia and sepsis. In addition to their importance as therapeutic targets, certain potassium channels are known for their beneficial roles in anaesthesia, cardioprotection and neuroprotection. Some types of potassium channels present in the plasma membrane of various cells have been found in the inner mitochondrial membrane as well. Potassium channels have been proposed to regulate mitochondrial membrane potential, respiration, matrix volume and Ca+ ion homeostasis. It has been proposed that mitochondrial potassium channels mediate ischaemic preconditioning in various tissues. However, the specificity of a pharmacological agents and the mechanisms underlying their effects on ischaemic preconditioning remain controversial. The following potassium channels from various tissues have been identified in the inner mitochondrial membrane: ATP-regulated (mitoKATP) channel, large conductance Ca2+-regulated (mitoBKCa) channel, intermediate conductance Ca2+-regulated (mitoIKCa) channel, voltage-gated (mitoKv1.3 type) channel, and twin-pore domain (mitoTASK-3) channel. It has been shown that increased potassium flux into brain mitochondria induced by either the mitoKATP channel or mitoBKCa channel affects the beneficial effects on neuronal cell survival under pathological conditions. Recently, differential distribution of mitoBKCa channels has been observed in neuronal mitochondria. These findings may suggest a neuroprotective role for the mitoBKCa channel in specific brain structures. This minireview summarises current data on brain mitochondrial potassium channels and the efforts to identify their molecular correlates.

Opis:
In the last two decades, more and more publications pedagogical and psychological referring to researchin the field of neurobiology. They appear in them new concepts and names of new disciplines such as neuropedagogy, neurodidactics or educational neuroscience and neuropsychology education. The US, the UK and Canada have attempted to standardize terminology and to clarify the scope of research across disciplines. This publication is not only an attempt to present the theoretical concept of the origin and interrelationships of newly established disciplines based on international scientific sources. The author has decided to embed analyses on the specifics of Polish terms to propose names for an interesting and new field known as Mind, Brain and Education (MBE).

Opis:
Psychedelics, as a plant-derived material, have been used for millennia in reli- gious and medical practices. They produce an altered state of consciousness characterized by distortions of perception, hallucinations, dissolution of self boun- daries and the experience of unity with the world. Classic psychedelics, also known as serotonergic hallucinogens, such as lysergic acid diethylamide (LSD) and psilocybin were extensively investigated in substance-assisted psychotherapy during the 1950s–1960s. These early clinical studies reported improvement rates in patients with various forms of depression, anxiety disorders, alcohol dependen- ce. The development of modern neuroimaging techniques renewed interest in the investigation of psychedelics as a class of drugs that may reopen multiple the- rapeutic benefits. Current behavioral and neurochemical data show that psy- chedelics induce their psychological effects primarily via 5-hydroxytryptamine type 2A (5-HT2A) receptor activation and modulate neural circuits involved in mood and affective disorders. Clinical trials examining psilocybin have suggested that the compound relieves symptoms of depression and anxiety with rapid onset and longer duration. Serotonergic psychedelics enhance expression of neurotro- phic factors such as brain-derived neurotrophic factor (BDNF) as well as expres- sion of genes associated with synaptic plasticity and stimulate synapse formation. These effects are similar to those produced by fast-acting antidepressant keta- mine. Basic science research can reveal the neural mechanism of psychedelics action and how they can be used for treatment.

Opis:
Art and the notion of beauty related thereto are both disciplines and states which are quite unobvious and thereby requiring us to ask the question: Why is it that human beings have in their minds an inherent need to witness the beauty along with - resultant - need to create and receive art? The author of the text - by devising some neurobiological tools - attempts to elicit relative laws of beauty reception, and simultaneously she utilises the instruments of neuroaesthetics, which is a field of science that investigates the impact of art on processes taking place in the human brain. She explores, among other things, mechanisms put to use, consciously or otherwise, by artists in order to make their works a peculiar stimulus. The author describes a series of “tricks” used by visual arts creators who model the particular ways the visual perception processes function.

Opis:
Badania nad jąkaniem skoncentrowane wokół patologii układu nerwowego są aktualnie jednymi z najbardziej dynamicznie rozwijających się. U ludzi jąkających się stwierdza się różnego rodzaju nieprawidłowości dotyczące anatomii ośrodków odpowiedzialnych za realizację funkcji językowych, zaburzenia funkcjonalne, nieprawidłową lateralizację funkcji językowych oraz zaburzenia połączeń między ośrodkami. Wiele badań dowodzi, że u jąkających się występują zaburzenia funkcjonalnej asymetrii mózgu. Lewopółkulowa reprezentacja mowy nie jest tak wyraźnie zaznaczona jak u osób mówiących płynnie. Płynność mówienia możliwa jest dzięki realizacji planu motorycznego, który u jąkających się jest nieprawidłowo zsynchronizowany. Występuje też wadliwa współpraca pomiędzy programem lingwistycznym a jego motorycznym wykonaniem. Dysfunkcje dotyczą nie tylko obszarów ekspresyjnych mowy, ale także ośrodków słuchowych, których prawidłowe funkcjonowanie jest niezbędne dla prawidłowego przebiegu mowy. Badania dowodzą, że słuchowe sterowanie własną mową za pomocą sprzężenia zwrotnego jest u osób jąkających się zaburzone, a jednej z przyczyn upatruje się w nieprawidłowościach anatomicznych i funkcjonalnych obszaru słuchowego. Wyniki badań dotyczące budowy mózgu i jego funkcjonowania u osób jąkających się wskazują na liczne nieprawidłowości. Dotyczą one całego układu funkcjonalnego mowy. Warto podkreślić, że różnice funkcjonalne pojawiają się w sytuacji, kiedy jąkający się mówią lub nawet wtedy, kiedy wyobrażają sobie, że mówią.
Currently, stuttering studies focused on central nervous system pathology are one of those which develop most dynamically. Stutterers display various disorders within the anatomy of centres which control realization and abnormal lateralization of language functions, as well as functional disorders. Abundant research has proved that stutterers display disturbed functional brain asymmetry. The left hemisphere speech representation in a stutterer’s brain is marked less clearly than in the case of fluent speakers. Speech fluency comes from realizing the motor plan, which is abnormally synchronised in a stutterer’s brain. Similarly, stuttering people display incorrect cooperation between the language program and its motor performance. Dysfunctions are observed not only in the expressive speech areas, but also in the hearing centres, whose proper functioning is vital for normal course of speech. Research has showed the disturbed auditory feedback control of speech among stutterers, which is thought to be caused by anatomical and functional abnormalities within the brain hearing area. Results of studies over stutterers’ brain structure and functioning point to numerous abnormalities observed in the whole functional system of speech. Importantly, these functional differences occur among stutterers during actual speech and even when speaking is only visualized in the stutterer’s mind.
