introduction: this study was conducted to determine the possible beneficial results of l-arginine on prefrontal cortex of rats which impressed by immobilization stress to define the synchronous impression of stress and nitric oxide (no) on evolution of prefrontal cortex of rats after birth. methods: forty-eight one month, male wistar rats were divided into two groups: stressed and non-stressed....

The brain requires O2 and nutrition to keep functioning. It is known that concentration converts the polarity of vessel response near activated neuron in hippocampus. However, it remains unclear whether cortex. We investigated comparison arteriole stimulated neurons cerebral cortex slices between 95% 20% medium. showed diameter blood vessels decreased under when pyramidal cells were increased w...

Systematic reviews of neuroimaging studies confirm stimulus-induced activity in response to verbal and non-verbal self-referential processing (SRP) cortical midline structures, temporoparietal cortex insula. Whether SRP can be causally modulated by way non-invasive brain stimulation (NIBS) has also been investigated several studies. Here we summarize the NIBS literature including 27 task-based ...

A role of the motor cortex in tremor generation essential (ET) is assumed, yet directionality corticomuscular coupling unknown. Our aim to clarify cortex. To this end we also study ‘familial cortical myoclonic with epilepsy’ (FCMTE) and slow repetitive voluntary movements a known drive. Directionality (EEG-EMG) was studied renormalized partial directed coherence (rPDC) during 25 ET patients, he...

Abstract The link between cognitive function and emotion regulation may be helpful in better understanding the onset, maintenance, treatment for depression. However, it remains unclear whether there are neural correlates dysregulation deficits To address this question, we first review representations of depression (including control biases). Based on comparisons versus deficits, propose an acce...

background: central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. our previous work showed that inhibition of angiotensin converting enzyme (ace) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (i/r) injuries. this study evaluated the impacts of post-ischemic inhibition of ace, enalapril, on brain inf...

traumatic brain injury (tbi) is a common injury leading to child disability and is associated with a variety of long-term cognitive, social, and behavioral dysfunctions. emotion perception (ep) starts up an integral part of social communication is critical to achieve developmentally appropriate goals. this skill, which emerges relatively early in development, is driven by increasing connectivit...

alzheimer’s disease (ad) is a uniquely human disorder. although the pathogenesis of ad is not fully understood, growing evidence indicates that the deposition of beta-amyloid (aβ) and the local reactions of various cell types to this protein play major roles in the development of the disease. in the present study transgenic mice expressing mutant amyloid precursor protein (app) has been used. t...

introduction: in the present study the effect of nucleus basalis of meynert (nbm) destruction on the temporal characteristics of response integration evoked by multiple whisker stimulations in rat barrel cortex was studied. material and methods: wistar male rats weighing 250-350 g were used. the animals were randomly distributed into two groups: in the first group bilateral nbm lesions was indu...

Objective(s): Behavioral and neuroimaging studies have shown that transcranial direct current stimulation, as a non-invasive neuromodulatory technique, beyond regional effects can modify functionally interconnected remote cortical and subcortical areas. In this study, we hypothesized that the induced changes in cortical excitability following the application of cathodal or anodal tDCS over the ...
