Opis:: Introduction and objectives. The aim of the study was to asses the impact of long-term therapy with the second generation antiepileptic drug levetiracetam (LEV) with arachidonyl-2’-chloroethylamide (ACEA), a highly selective cannabinoid CB1 receptor agoniston the process of neurogenesis in a mouse pilocarpine model of epilepsy (PILO). Additionally, a relationship was established between the treatment with ACEA in combination with LEV, and hippocampal neurogenesis in mouse PILO brain. Materials and method. All experiments were performed on adolescent male CB57/BL mice injected i.p. with LEV (10 mg/kg), ACEA (10 mg/kg) and PMSF (30 mg/kg) (phenylmethylsulfonyl fluoride — a substance protecting ACEA against degradation by the fatty-acid amidohydrolase), pilocarpine (PILO, a single dose 290 mg/kg) and methylscopolamine (30 min before PILO to stop the peripheral cholinergic effects of the pilocarpine, 1 mg/kg). The process of neurogenesis was evaluated after10 days treatment with LEV and ACEA. Results. Obtained results indicated that the combinations of ACEA+PMSF+LEV and ACEA +PMSF increased the total number of total newborn cells compared to the control. Moreover, ACEA+PMSF administered alone and in combination with LEV had a significant impact on neurogenesis increasing the total number of newborn neurons compared to the control group. Neither LEV nor PMSF had a significant impact on the number of proliferating cells and newborn neurons when compared to the control PILO group. In turn, LEV administered alone decreased significantly the number of astrocytes. However, ACEA+PMSF has demonstrated significant increase of astrocytes compare to control mice. Conclusions. These data provide substantial evidence that the combination of LEV+ACEA significantly increases the level of newborn neurons in the PILO dentate subgranular zone.

Opis:: The present study investigated the chemical coding of neurons and nerve fibres in local laryngeal ganglia in pigs (n=5) using double-labelling immunohistochemistry. Virtually all the neurons were cholinergic in nature (ChAT- or VAChT-positive). Only very solitary, small nerve cells (presumably representing interneurons) stained intensely for adrenergic marker, DβH. Many neurons also contained immunoreactivity for NOS (91%), VIP (62.7%), NPY (24.7%), galanin (10%), SP (1.3%) and CGRP (5.3%). No neurons expressing somatostatin or Leu-enkephalin were observed. Nearly all the neuronal somata were densely supplied with varicose cholinergic nerve terminals, which presumably represented preganglionic axons, and some of them were also closely apposed with CGRP- and/or SP-positive varicose nerve endings, which were putative collaterals of extrinsic primary sensory fibres. In conclusion, this study has revealed that intrinsic neurons in the porcine larynx, like in many other mammalian species studied, should be classified as parasympathetic cholinergic neurons expressing biologically active substances, predominantly NOS and VIP. Furthermore, they are likely to receive inputs from not only preganglionic neurons but also primary sensory nerve cells. Finally, it appears that the information on the occurrence of the local laryngeal ganglia should be regularly included in textbooks dealing with the cranial portion of the parasympathetic nervous system in mammals.

Opis:: The present study investigated the distribution and chemical properties of nerve cell bodies within the trunk of the vagus nerve in juvenile female pigs (n=4) using double-labelling immunofluorescence. The neurons appeared mostly as single cells or formed streaks of cells or small ganglia. Many of the perikarya were cholinergic (VAChT-positive; VAChT+) or adrenergic (DβH+) in nature and no SP+ or CGRP+ neurons were encountered. There were no distinct left-right differences regarding the number and chemical coding of the neuronal somata, however, these characteristics significantly varied between particular nerve segments investigated. The vagosympathetic trunks, and thoracic and abdominal segments of the vagus nerve contained on average (the numerical values represent the means for both the left and right corresponding nerve segments) 142, 236, and 111 PGP 9.5-positive neurons, respectively. Proportions of cholinergic and adrenergic neurons were as follows: 0% and 100%, 54.2% and 33.2%, and 52.8% and 35.4%, respectively. Relatively many neurons in the thoracic and abdominal segments stained also for NOS (39.2% and 39.9%, respectively). It remains to be determined whether the porcine intravagal neurons represent a developmental relic, or whether they have any specific functional significance.

Opis:: This work presents concepts of the use of algorithms inspired by the functions and properties of the nervous system in dense wireless networks. In particular, selected features of the brain consisting of a large number of nerve connections were analyzed, which is why they are a good model for a dense network. In addition, the action of a selected cells from the nervous system (such as neuron, microglia or astrocyte) as well as phenomena observed in it (e.g. neuroplasticity) are presented.

Opis:: The discovery of mirror neurons and the characterization of their response properties is certainly an important achievement in neurophysiology and cognitive neuroscience. The reference to the role of mirror neurons in ‘reading’ the intentions of other creatures and in the learning process fulfils an explanatory function in understanding many cognitive phenomena beginning from imitating, towards understanding, and finishing with complex social interactions. The focus of this paper is to review selected approaches to the role of mirror neurons in mental activity as understanding, and to conclude with some possible implications for researches on mirror neurons for philosophical theories of understanding.

Tytuł:: Neuroplasticity and Microglia Functions Applied in Dense Wireless Networks

Opis:: This paper presents developments in the area of brain-inspired wireless communications relied upon in dense wireless networks. Classic approaches to network design are complemented, ﬁrstly, by the neuroplasticity feature enabling to add the learning ability to the network. Secondly, the microglia ability enabling to repair a network with damaged neurons is considered. When combined, these two functionalities guarantee a certain level of fault-tolerance and self-repair of the network. This work is inspired primarily by observations of extremely energy eﬃcient functions of the brain, and of the role that microglia cells play in the active immune defense system. The concept is veriﬁed by computer simulations, where messages are transferred through a dense wireless network based on the assumption of minimized energy consumption. Simulation encompasses three diﬀerent network topologies which show the impact that the location of microglia nodes and their quantity exerts on network performance. Based on the results achieved, some algorithm improvements and potential future work directions have been identiﬁed.

Tytuł:: Perception-based reasoning: evaluation systems

Wydawca:: Politechnika Gdańska
Tematy:: fuzzy sets

Opis:: A perception-based interpretation of evaluation systems is proposed in this paper. Thus, a perception-based approach to create intelligent systems is considered. The evaluation systems can be employed eg. in order to assess student exams, as well as to other applications. Evaluation marks used in these systems are given as perceptions expressed by words. The words play the role of labels of perceptions, and are represented by fuzzy sets. This means that the idea of perception-based systems, introduced by Zadeh, is applied. Various algorithms of overall assessment are suggested in this paper. Overall evaluation is produced as an aggregation of component evaluation marks. Systems of this kind can be obtained using fuzzy neurons, so fuzzy neural networks are also mentioned as a method of perception-based reasoning. The usefulness in artificial intelligence of both fuzzy sets and neural networks, and especially a combination of these, is shown.
