Studying the visual perception by means of EP recording in the visual and motor cortical areas and cortical reactions during hand movements revealed resemblance of these reactions in children to those in patients with endogenous (cyclophrenia and low-progredient schizophrenia) depressive disorders. In perception, the latency of the early and middle EP components was reduced. An increase in reactivity of the right hemisphere and ipsilateral reactions were induced by the movement.

Transcranial direct current stimulation for patients with walking difficulties caused by cerebral small vessel disease: a randomized controlled study.

Introduction: Cerebral small vessel disease (CSVD) is a chronic systemic degenerative disease affecting small blood vessels in the brain, leading to cognitive impairments. Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique that applies low electrical currents to the scalp, shows promise in treating cognitive and movement disorders. However, further clinical evaluation is required to assess the long-term effects of tDCS on neuroplasticity and gait in patients with CSVD.

The primary motor cortex (M1) is believed to be a cortical center for the execution of limb movements. Although M1 neurons mainly project to the spinal cord on the contralateral side, some M1 neurons project to the ipsilateral side via the uncrossed corticospinal pathway. Moreover, some M1 neurons are activated during ipsilateral forelimb movements.

Background: Certain cognitive processes require inhibition provided by the somatostatin (SST) class of gamma-aminobutyric acid (GABA) neurons in the dorsolateral prefrontal cortex (DLPFC). This inhibition onto pyramidal neuron dendrites depends on both SST and GABA signaling. Although SST mRNA levels are lower in the DLPFC in schizophrenia, it is not known if SST neurons exhibit alterations in the capacity to synthesize GABA, principally via the 67-kilodalton isoform of glutamic acid decarboxylase (GAD67).

Relational integration is a key subcomponent of working memory and a strong predictor of fluid intelligence. Both relational integration and fluid intelligence share a common neural foundation, particularly involving the frontoparietal network. This study utilized a randomized controlled experiment to examine the effect of relational integration training on brain networks using electroencephalogram (EEG) and microstate analysis.

A key response to acute stress is the increased brain synthesis of the neurosteroid allopregnanolone (AP). Although the rate-limiting step of this reaction is catalyzed by 5α-reductase (5αR), the role of its two primary isoenzymes, 5αR1 and 5αR2, in stress reactivity remains unclear. Here, we found that acute stress led to increased levels of 5αR2, but not 5αR1, in the medial prefrontal cortex (mPFC) of male, but not female, rats.
