aim of this research was exploring effect of transcranial direct current stimulation (tdcs) on working memory (wm) in dorsolateral prefrontal cortex (dlpfc) region in healthy people.the method used in this research was experimental with random assignment and control group. the population was male students of kharazmi university in range of 18 to 23 years old. thirty participant undertook three ...

Emotion regulation decreases the processing of arousing stimuli, as indexed by the late positive potential (LPP), an electrocortical component that varies in amplitude with emotional arousal. Emotion regulation increases activity in the prefrontal areas associated with cognitive control, including the dosolateral prefrontal cortex (DLPFC). The present study manipulated working memory load, know...

objective: recent studies on treating obsessive compulsive disorder (ocd) have investigated noninvasive brain stimulation techniques such as transcranial direct current stimulation (tdcs) to improve patients’ impaired emotion and cognition. however, such experiments have yielded mixed results, especially with respect to cognition. this study aimed to investigate whether anodal and cathodal tdcs...

modulation of dorsolateral prefrontal cortex (DLPFC) activity using non-invasive brain stimulation, such as transcranial direct current stimulation (tDCS), enhanced the prospects of substance use disorders rehabilitation. Methods: we carried out a randomized sham-controlled clinical trial to assess the effect of repeated tDCS at DLPFC on drug craving in 30 abstinent male methamphetamine users. ...

The purpose of this study was to investigate the effect of stereoscopic display alignment errors on visual fatigue and prefrontal cortical tissue hemodynamic responses. We collected hemodynamic data and perceptual ratings of visual fatigue while participants performed visual display tasks on 8 ft × 6 ft NEC LT silver screen with NEC LT 245 DLP projectors. There was statistical significant diffe...

Repeated stimulation dorsolateral-prefrontal cortex improves executive dysfunctions and craving in drug addiction: A randomized, d...

BackgroundTranscranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) hypothetically modulates cognitive functions by facilitating or inhibiting neuronal activities chiefly in cerebral cortex. The effect of tDCS deeper brain region, basal ganglia-cortical circuit, remains unknown.ObjectiveTo investigate interaction between ?-aminobutyric acid (GABA) concentratio...

BACKGROUND Neuroimaging studies have demonstrated changes in the dorsolateral prefrontal cortex (DLPFC) and anterior cingulate cortex (ACC) in major depression. AIMS We investigated the expression of cell adhesion molecules (CAMs) in the prefrontal cortex in depression. METHOD Immunohistochemistry to localise CAMs in post-mortem tissue from 20 subjects with major depression and 20 controls,...

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words...
