    Opis:
    Left-handers have been persecuted by right-handers for millennia. This right bias is evident cross-culturally, linguistically (right is literally and figuratively ‘right’, with lefties being described as ‘gauche’, ‘sinister’ and ‘cack-handed’), and environmentally (e.g., equipment design, including power tools, ticket machines, and lecture-room desks). Despite this, the proportion of left-handers has remained constant at approximately 10% of the hominid population, implying that though there are costs associated with left-handedness (if there were not, the proportions of left- and right-handers would be 50:50), left handers must also enjoy fitness advantages that maintain the genes for left-handedness in the population. This paper reviews the costs and benefits of being left-handed, exploring research examining the effects of handedness on brain structure, cognitive function, and human behaviour. The research confirms a variety of left-hander advantages, including some cognitive superiorities, higher wages, and greater sporting and fighting prowess. On the other hand, left-handedness is also associated with significant fitness costs, including an increased risk of accidents, higher substance abuse susceptibility, and earlier death, in comparison with right-handers. In sum, left-handedness confers both costs and benefits, with the latter outweighing the former, maintaining the genes for left-handedness in the population.

    Opis:
    Background: It has been evidenced that the outcome of a CVA patient differs as a function of the cerebral hemisphere that is damaged by the stroke, especially in terms of emotional changes. In contrast, the Bi-Hemispheric Model of Emotion posits that each hemisphere has its own emotional specialization. The current experiment tested the competing predictions of the two theoretical perspectives in a mixed sample of left cerebrovascular accident (LCVA) patients and right cerebrovascular accident (RCVA) patients using a Dichotic Listening task and the Affective Auditory Verbal Learning Test (AAVLT). Heart Rate (HR) and Pulse Oxygen Saturation (SpO2) were recorded as sympathetic measures. It was expected that the predictions of the Bi-Hemispheric Model would be supported. A series of mixed design ANOVAs were used to analyze the data. Material/Methods: Participants consisted of 21 patients grouped into either post-acute status left cerebrovascular accident (LCVA) or right cerebrovascular accident (RCVA). Tests included the The Dichotic Listening test, The Affective Auditory Verbal Learning Test (AAVLT), HR and Sp02 measurement using a Fingertip Pulse Oximeter and the Mood Assessment Scale for depression. Results: Results revealed that both groups exhibited decreased auditory detection abilities in the ear contralateral to CVA location. Additionally, CVA patients recalled significantly more positive words than negative or neutral words and exhibited a significant learning curve. LCVA patients exhibited a recency effect, while RCVA patients exhibited a heigh tened primacy effect. Findings from the HR and Sp02 measures suggested a parasympathetic response to emotionally neutral information as well as an impaired sympathetic response to emotionally negative information in RCVA patients. Conclusions: The results lend partial support to the hypothesis drawn from the Bi-Hemispheric Model of Emotion, as evidenced by the diametrically opposite effects in these groups, which reflects opposing cerebral processes.

    Opis:
    The performance of learned manual gestures (praxis) and the production of speech are thought to depend on related neural processes. If this relationship is not invoked by an unknown, third variable then shifts in their laterality, including dissociations of these two functions, would be unlikely unless the sharing of some neural resources with other functions is advantageous. This could be the case in lefthanders, in whom actions requiring manual precision are controlled by their right hemispheres, and whose representations could attract the control of skilled gesture. Functional neuroimaging (fMRI) was used to study praxis and language functions. Their lateralization indices were measured in 56 consecutively tested lefthanders (28 females), with the mean age of 23.3±4.9 years (range 18.4 – 47 years), and an Edinburgh Handedness Inventory quotient between –100 and –55.6 (with the mean of –83.8±14.2). We show that atypical, bilateral organization or right-lateralization of praxis is more common than atypical organization/lateralization of language, observed, respectively, in 23 (41%) vs. 15 (26.8%) of cases. Specifically, we found: (a) seven cases (12.5%) of clear, and an additional three cases (5.4%) of less pronounced dissociations of atypically represented praxis from typically represented language; (b) 13 cases (23.2%) with atypically organized praxis also associated with atypically organized language, and (c) only two cases (3.6%) of rather strongly atypical lateralization of language, yet with quite typical lateralization of praxis. These outcomes are consistent with an idea that, in some lefthanders, the guidance of skilled manual actions can profit from tighter links with the right hemisphere, whose motor specialization is linked in this particular population to manual precision, but in general to attentional resources, visuo-spatial processing and even bimanual coordination. Because of the presumed links of praxis with productive language, such transfers are often, and unsurprisingly accompanied by the reorganization of the latter. Yet, the very rare cases of reversed language functions, without any pronounced shifts in representations of praxis, indicate that such a pattern of segregation – or inverse dissociation – of these two functions could be maladaptive.

    Opis:
    The aim of this study was to analyze a case series with acquired alexia after stroke within the posterior areas of the left hemisphere, in the context of the current criteria for pure alexia and their relevance to the set of symptoms observable in clinical practice. Seven patients with ischemic strokes and an initial diagnosis of pure alexia were enrolled for detailed analysis. The evaluation consisted of neuropsychological assessment in the form of standardized tests and non-standardized reading tasks, while oculomotor activity during reading was measured. Language functions, visual object and space perception, verbal and nonverbal memory, and visuospatial constructional ability were among the domains assessed. In five of the participants, pure alexia was recognized based on sig- nificant and specific discrepancies between test scores, indicating primary abnormalities in the visual processing of letter strings as a basic mechanism of the disorder. In most of the patients, coexisting cognitive deficits were revealed; however, these were dispropor- tionately milder and less functionally significant than reading disturbances. Pure alexia is a relatively rare disorder after a stroke, but it considerably affects the quality of everyday independent functioning. Its clinical characteristics in practice rarely meet all the criteria proposed in the subject literature. The differential diagnosis of this form of alexia and other reading disorders requires detailed clinical analysis.

    Opis:
    Previous research has established that photos of great apes, including humans, show a left cheek bias. As this bias is absent in images of lower primates and other animals, phylo-genetic proximity appears to influence humans’ depictions of nonhuman species. However Thomas et al.’s (2006) finding of a left cheek bias for dogs challenges this argument. As their analyses were underpowered, the present study sought to replicate Thomas et al.’s study with a larger sample to help determine whether human depictions of non-human animals vary as a function of their evolutionary relatedness. Photographs (N=2883) were sourced from Instagram’s ‘Most Recent’ feed using hashtags that matched Thomas et al.’s Google Image search terms: #dog, #cat, #fish, #lizard, #cute- baby, #cryingbaby. The first 401 lateral images for each hashtag were coded for pose orientation (left, right). Replicating Thomas et al., results confirmed a left cheek bias for mammals but not nonmammals. The left cheek bias was driven by images of human infants; there were no cheek biases for images of nonhuman animals (dogs, cats, lizards, fish). As a left cheek bias was evident in photos of primates (#cutebaby, #cryingbaby), but absent for other mammals (#dog, #cat) and nonmammals (#lizard, #fish), the data support the argument that phylogenetic proximity influences posing biases.

    Opis:
    The cerebral lateralization of language has attracted great research interest. Nevertheless, the bulk of the work focuses on language production and comprehension; research on cerebral lateralization during writing is limited. The present study assessed cerebral lateralization in 60 participants (mean age = 26.65 years, SD = 6.05, range = 20-44), 30 right-handers (14 men) and 30 left-handers (16 men), during written language production by means of functional transcranial Doppler ultrasonography (fTCD) for the first time. Findings show that left-hemispheric lateralization is observed during silent word production, for both left- and right-handers. However, during written word production, the degree of typical (left) hemispheric lateralization was significantly increased for right-handers, while left-handers presented atypical (right) hemispheric lateralization. Importantly, the difference between silent and written word generation was significantly higher in left- compared to right-handers. No main effect of sex or interactions with sex were observed. Findings suggest that a wider network of right-hemispheric areas is used during writing in left-handers. Thus, the known differences in cerebral lateralization between right- and left-handers are stronger during written language production. However, the relative contribution of language and motor areas needs to be further elucidated.

    Opis:
    The search for neuromarkers is a very promising way to improve psychiatric and psychological care. They are now considered to be an innovative diagnostic tool in psychiatry and neuropsychology, but more broadly in all human health sciences. The aim of our study was to find the neuromarker of anxiety in a patient who had experienced a Transient IschemicAttack (TIA) of the left brain hemisphere as a result of a critical stenosis of the Internal Carotid Artery (ICA) operated on byendarterectomy (CEA). We will present the case of a 54-year-old man,an architect, who experienced a Transient Ischemic Attack (TIA) of the left brain hemispherecaused by a critical stenosis of theInternal Carotid Artery (ICA) and was treated successfully with surgical endarterectomy (CEA). One year after the surgery itself, the patient developed severe postoperative anxiety, headaches, difficulty in sleepingas well as the inability to continue working in his profession. Strong anxiety was notedon the adapted 100-millimeter Visual Analogue Anxiety Scale (VAAS). The patient was assessed using the Human Brain Index (HBI) methodology (Kropotov 2009; 2016; 2017; Pąchalska, Kaczmarek&Kropotov 2014) which consisted of recording 19-channel EEG in resting state conditions, during the cued GO/NOGO task and comparing the parameters of EEG spectra and Event-Related Potentials (ERPs) with the normative and patient databases of the Human Brain Index(HBI). No signs of cognitive dysfunction was found, however an excessive Rolandic beta was observed. In line with the working hypothesis as to the presence of an anxiety neuromarker, the patient’s studies confirmed an increased P1 time wave in the left hemisphere of the brain in ERP in response to visual stimuli, i.e. an anxiety neuromarker. Following the detection of this neuromarkera specific anodic Transcranial Direct Current Stimulations (tDCS) pro- tocol was proposed (see: Kropotov 2016; Pąchalska, Kaczmarek & Kropotov 2020). Ten tDCS sessions were performed and the postoperativeanxiety was found to be resolved. The patient returned to work. The use of Human Brain Index (HBI) methodologyenabling the isolation of the Event Related Potentials (ERPs) patterns revealed the presence of a distinct anxietyneuromarker. Neurotherapy with the use of tDCS allowed the reduction of anxiety symptoms and the patient’s return to work. The above case study indicates the necessity to use new neurotechnologies in the diagnosis of mental diseases, with particular emphasis on postoperative anxiety. ------------------------------------------------------------------------------------------------------------------------------------

    Opis:
    The purpose of this study was to evaluate pain reduction as the main parameter for monitoring improvements in Health-Related Quality of Life (HRQoL) in a female patient following endovascular treatment of Pelvic Congestion Syndrome (PCS). A 38-year-old female patient with chronic intermittent, “dragging” abdominal pain, lasting more than two years, mainly in the lower abdomen, radiating to the sacral region, underwent SARS CoV-2 infection in October 2021, and COVID-19, which lasted 10 days. Eight months later, complaints of pain in the lower abdominal area, during the menstrual cycle, during prolonged standing, after sports activities and during and after intercourse, increased. The patient was compelled to begin diagnosis of these complaints due to the severe pain and concerns about whether she had contracted cancer of the cervix uteri. She was diagnosed on transvaginal ultrasound-Doppler and Angio-MR of the pelvic vessels with PCS. Treatment was undertaken at the Department of Vascular Surgery and Endovascular Interventions, St. John Paul II Hospital, Krakow, Poland. Intraoperatively, after confirmation through selective angiography, of previously diagnosed insufficiency of the left ovarian vein (LOV) and of the parametrial veins (PMV), the selective obliteration was performed with an adhesive dedicated to endovascular closure of veins and vascular malformations (Glubran®2). The range of pain intensity, according to theVisual Analogue Scale (VAS), in Exam. 1 (before surgery), was in the premenstrual period (BM) 7.0 points, which increased during menstruation (DM) or after intense activity (AIA) to 8.0 points, and occasionally during and after intercourse even to 9.0 points. These values were very high, indicating that pain significantly affected the patient's quality of life. The extent of pain severity decreased significantly in Study 2 (two months after surgery) and Study 3 (four months after surgery) and was 2.0 points in the premenstrual period (BM), which increased only slightly during menstruation (DM) or after intense activity (AIA) to 3.0 points, and decreased again to 2.0 points during and after intercourse. The patient reported that the procedure significantly and positively affected her functioning in daily life, especially in caring for a young child, which is evidence of the achievement of HRQoL improvement. Endovascular treatment for Pelvic Congestion Syndrome (PCS) was effective in reducing pain and improving the Health-Related Quality of Life (HRQoL) of a patient with PCS.

    The left hemiface expresses emotion more intensely than the right. Because emotional expressions contract the facial muscles and wrinkle the skin, theoretically the left hemiface’s greater expressivity should prompt more pronounced expression lines and wrinkles on the left than right side of the face. As wrinkles are the most salient age cue, we investigated whether the left hemiface consequently appears older than the right. Two hundred and sixty participants (F=148; M=112) viewed booklets containing pairs of left-left and right-right chimeric faces of eight models (M=F). For each trial participants were asked to make a two alternative forced choice response indicating which image looked older. Results confirmed a left cheek bias, with participants more likely to select left-left than right-right chimeras. Whilst participant gender did not influence perceptions, model gender predicted cheek selections: responses to female models drive the overall left cheek bias. The left cheek (56.8%) appeared older than the right cheek (43.2%) for female models, whereas there was little difference in perceived age between male models' left (50.8%) and right (49.2%) cheeks. Given that youth influences perceptions of female beauty, these findings complement previous research and offer a potential explanation for why the left side of females’ faces are judged less attractive: the right cheek appears younger.
