introduction: working memory plays a critical role in cognitive processes which are central to our daily life. neuroimaging studies have shown that one of the most important areas corresponding to the working memory is the dorsolateral prefrontal cortex (dlfpc). this study was aimed to assess whether bilateral modulation of the dlpfc using a noninvasive brain stimulation, namely transcranial di...

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 whethe...

Objective: Previous studies have reported dorsolateral prefrontal cortex (DLPFC) and posterior parietal (PPC) activation during the performance of spatial working memory (SWM), so we decided to investigate the comparison of Transcranial Direct current stimulation (tDCS) effect between these two areas. Methods: Fifty-four healthy right-handed students (27 female, 27 male; age= 24.3±.2 years) w...

Trust plays an important role in the human economy and people’s social lives. is affected by various factors related to many brain regions, such as dorsolateral prefrontal cortex (DLPFC). However, few studies have focused on impact of DLPFC trust through transcranial direct current stimulation (tDCS), although abundant psychology neuroscience theoretically discussed possible link between activi...

Previous studies have established that transcranial direct current stimulation (tDCS) is a powerful technique for manipulating the activity of the human cerebral cortex. Many studies have found that weighing the risks and benefits in decision-making involves a complex neural network that includes the dorsolateral prefrontal cortex (DLPFC). We studied whether participants change the balance of r...

PURPOSE The elucidation of thalamocortical connections between the mediodorsal nucleus (MD) of thalamus and the prefrontal cortex (PFC) is important in the clinical fields of neurorehabilitation and psychiatry. However, little is known about these connections in human brain. We attempted to identify and investigate the anatomical characteristics of the thalamocortical connection between MD and ...

Cognitive regulation is often used to influence behavioral outcomes. However, the computational and neurobiological mechanisms by which it affects behavior remain unknown. We studied this issue using an fMRI task in which human participants used cognitive regulation to upregulate and downregulate their cravings for foods at the time of choice. We found that activity in both ventromedial prefron...

Abstract The think-aloud protocol provides researchers an insight into the designer's mental state, but little is understood about how thinking aloud influences design. study presented in this paper sets out to measure cognitive and neurocognitive changes designers when aloud. Engineering students (n=50) were randomly assigned or control group. Students outfitted with a functional near-infrared...

Structural and functional abnormalities of the prefrontal cortex seem to correlate with fatigue in patients with chronic fatigue syndrome (CFS). We consecutively applied facilitatory high-frequency repetitive transcranial magnetic stimulation (rTMS) to the dorsolateral prefrontal cortex (DLPFC) of seven CFS patients over three days. Five patients completed the 3-day protocol without any adverse...

Background: Recent studies showed that in healthy controls and aphasic patients, inhibitory trains of repetitive transcranial magnetic stimulation (rTMS) over the right prefrontal cortex can improve phonemic fluency performance, while anodal direct current (tDCS) left performance naming semantic tasks. Objective: This study aimed at investigating effects cathodal tDCS or dorsolateral (DLPFC) on...
