Background: An electroencephalogram (EEG) is an accepted method in neurophysiology with a wide application. Different types of brain rhythms indicate that simultaneous activity of the brain cortex neurons depend on the person’s mental state. Method: we have focus on reviewing the existing literature pertaining to changes of the brain’s bioelectrical activity that recorded from the ...

Abstract Repeated sub-concussive impact (e.g . soccer ball heading), a significantly lighter form of mild traumatic brain injury, is increasingly suggested to cumulatively alter structure and compromise neurobehavioural function in the long-term. However, underlying mechanisms whereby repeated long-term sub-concussion induces cerebral structural changes are currently unknown. Here, we utilised ...

background: the effects of estrogene on central nervous system are still controversial. objective: we aimed to investigate the effects of raloxifene on the antioxidant enzyme [superoxide dismutase (sod) and catalase (cat)] activities and malondialdehyde (mda) levels in brain homogenates of ovariectomized female rats and its effect on cognitive process of learning. materials and methods: female ...

    Abstract   The Intraparenchymal schwannomas are very rare tumors with only 52 reported   cases . We describe a 38 years old man with eight months history of poorly controlled   seizures despite of medical therapy. On brain CT scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. On brain MRI the lesion   was hypointense in T1 and hyperintense in T...

The aim of the study was to determine immunohistochemical level glutamine synthetase (GS) expression in different brain regions conditions experimental acute liver failure rats.
 Materials and methods. conducted Wistar rats: 5 sham (control) animals 10 rats with acetaminophen induced model (AILF). GS sensorimotor cortex, white matter, hippocampus, thalamus, caudate nucleus/putamen carried ...

The molecular mechanisms generating the mania-like abnormal behaviors caused by diacylglycerol (DG) kinase (DGK) η deficiency remain unclear. Here, we found that DGKη knockout markedly increased dopamine (DA) levels in midbrain (DA-producing region, 2.8-fold) and cerebral cortex (DA projection 1.2-fold). Moreover, significantly augmented phosphorylated DA transporter (DAT) (1.4-fold increase), ...

What I cannot create do not understand — Richard Feynman 1978 Because primate cortical development exhibits numerous specific features, the mouse is an imperfect model for human development. Expansion of supragranular neurons evolutionary feature characterizing cortex. Increased production supported by a germinal zone innovation cortex: Outer SubVentricular Zone, which along with constitute pri...

Abstract Some evidence converges to consider that suicidal behaviour could be a separate diagnosis and emphasizes the relevance identify specific biomarkers. Identifying neural substrates of suicide attempt is key understanding etiology might helpful in reducing rates among psychiatric patients by promoting development novel therapeutic strategies based on behavioral neuroscience brain stimulat...
