Mammalian oocyte meiotic divisions are highly asymmetric and produce a large haploid gamete 2 small polar bodies. This relies on the ability of cell to break symmetry position its spindle close cortex before anaphase occurs. In metaphase II–arrested mouse oocytes, is actively maintained parallel cortex, until fertilization triggers sister chromatid segregation rotation spindle. The latter must ...

Purpose of work. To determine the nature changes in content dopamine and its metabolites cerebral cortex, hypothalamus cerebellum rats with chronic alcohol intoxication (CAI) against background physical inactivity (PI). Material methods. The experiments were carried out on outbred white male weighing 180-220 g. Modeling PI was by placing individual cages-pencil cases, limiting their mobility, f...

Background: Although in 2017 a repetitive transcranial magnetic stimulation (rTMS) protocol received Food and Drug Administration approval for the first time treatment of obsessive–compulsive disorder (OCD), which neural target should be used OCD are still debated. The aim present study was to perform systematic review meta-analysis available open sham-controlled trials. Methods: primary analys...

Exploring and establishing artificial neural networks with electrophysiological characteristics high computational efficiency is a popular topic in the field of computer vision. Inspired by working mechanism primary visual cortex, pulse-coupled network (PCNN) can exhibit synchronous oscillation, refractory period, exponential decay. However, evidence shows that neurons highly complex non-linear...

Working memory serves as a basis for many cognitive functions, including attention, decision-making, and learning. When engaged, it is often associated with an increase in the average neural firing rates across different sensory sensorimotor regions of brain. However, modulation rate extrastriate cortex, involved visual processing, has never been reported during maintenance information. Here, f...

linguatula serrata is a zoonotic parasite with global expansion, particularly in tropical and subtropical areas. the aim of this study was to evaluate the pathological lesions caused by l. serrata in mesenteric lymph nodes (mln) of water buffalo. to study the pathological lesions of nymphal stage in water buffaloes, enlarged and swollen mln were collected and examined. grossly, the mln were swo...

Olig1 and Olig2, two transcription factors, play regulatory function in the differentiation and specification of oligodendrocyte progenitor cells (OPCs). In this study the effects of electromagnetic fields (EMF) on total protein concentration ( TPC ) and Olig1 and Olig2 expression in the cerebral cortex of mouse was examined. Twenty-one Balb/c mice were separated into three groups: control, EMF...

Objective: Phantom limb pain (PLP) as neuropathic pain affects the life of amputees. It is believed an efficient PLP treatment should consider the underlying neurological mechanisms. Hereby, we investigated brain activity in PLP’s and relations to the psychological and cognitive dimension of chronic pain. We investigate differences in resting brain activities between amputees with and without p...

Background Alzheimer disease (AD) is a chronic disorder that affects millions of individuals worldwide. Olfactory dysfunction common symptom several neurological disorders including AD. can be an early alteration heralding the presence Studying pattern alterations in olfaction-related brain regions might help detection neurodegenerative diseases at earlier stage. Objectives this study are to as...
