The ventromedial and dorsolateral prefrontal cortex are two major regions that usually interact in serving different cognitive functions. On the other hand, these also involved processing of emotions but their contribution to emotional is not well-studied. In present study, we investigated role three dimensions (valence, arousal dominance) stimuli via ratings visual performed by study participants on dimensions. Twenty- healthy adult (mean age 25.21 ± 3.84 years) were recruited received...
Abstract Obsessive-compulsive disorder (OCD) is associated with a high disease burden, and treatment options are limited. We used intensified electrical stimulation in two dosages to target main circuitry the pathophysiology of OCD, left dorsolateral prefrontal cortex (l-DLPFC), pre-supplementary motor area (pre-SMA) assessed clinical outcomes, neuropsychological performance, brain physiology. In double-blind, randomized controlled trial, thirty-nine patients OCD were randomly assigned three...
Objective: This study examined effects of transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) and orbitofrontal (OFC) on major executive functions (EFs), including response inhibition, control, working memory (WM), cognitive flexibility/task switching in ADHD. Method: ADHD children received (a) left anodal/right cathodal DLPFC tDCS (b) sham Experiment 1 anodal DLPFC/right OFC tDCS, (c) 2. The intensity was mA for 15 min with a 72-hr interval between...
Objective: The purpose of this study was to improve the inhibitory control functions through transcranial direct current stimulation (tDCS) in adolescents with ADHD symptoms. Method: Twenty high school students symptoms participated single-blinded, crossover, sham-controlled study. All participants were tested during application Stroop and Go/No-Go tasks that is used measure control, using 1.5 mA tDCS for 15 min over left dorsolateral prefrontal cortex (DLPFC). Results: Anodal on DLPFC had...
Transcranial direct current stimulation (tDCS) has been shown to modulate subjective craving ratings in drug dependents by modification of cortical excitability dorsolateral prefrontal cortex (DLPFC). Given the mechanism methamphetamine (meth) users, we aimed test whether tDCS DLPFC could also alter self-reported abstinent meth users while being exposed cues. In this double-blinded, crossover, sham-controlled study, thirty two right-handed male were recruited. We applied 20 min 'anodal' (2...
BackgroundAccording to the neurocognitive model of addiction, development and maintenance drug addiction is associated with cognitive control deficits, as well decreased activity prefrontal regions, especially dorsolateral cortex (DLPFC). This study investigated how improving executive functions (EFs) impacts methamphetamine-use disorder, which has been less explored compared craving, but might be a central aspect for therapeutic efficacy DLPFC stimulation in addiction.MethodsWe assessed 10...
Abstract Verbal and figural fluency are related to executive functions (EFs), but the extent which they benefit from resources their respective cortical representations is not clear. Moreover, different brain areas cognitive involved in processing. This study investigated effects of modulation excitability left dorsolateral prefrontal cortex (l-DLPFC), temporal area right posterior parietal (r-PPC) with transcranial direct current stimulation (tDCS), on verbal fluency. Fifteen healthy adult...
This study aimed to investigate and compare the executive functions of students with depression, anxiety, stress symptoms those in healthy ones.This was a comparative non-clinical analysis. The population comprised all Shahid Beheshti University, Tehran, Iran. A total 448 were recruited using convenience sampling method. They also screened Depression Anxiety Stress Scales (DASS) test comprising 21 items. Of participants, 30 people depressed, 27 had 15 suffered from stress. Then, 50 control...
Social Anxiety Disorder (SAD) is the most common anxiety disorder while remains largely untreated. Disturbed amygdala-frontal network functions are central to pathophysiology of SAD, marked by hypoactivity lateral prefrontal cortex (PFC), and hypersensitivity medial PFC amygdala. The objective this study was determine whether modulation dorsolateral activity with a novel intensified stimulation protocol reduces SAD core symptoms, improves treatment-related variables, attention bias...
Abstract Children with attention deficit/hyperactivity disorder (ADHD) typically exhibit difficulties in emotion regulation. It has been shown that the dorsolateral prefrontal cortex (dlPFC) and ventromedial (vmPFC) are crucially involved these deficient processes. In this study, we aimed to explore impact of electrical stimulation over left dlPFC right vmPFC on regulation children ADHD. Twenty-four ADHD completed Emotional Go/No-Go 1-Back tasks while undergoing transcranial direct current...
Objective: Individuals with ADHD have deficits in reward processing and related cognitive tasks such as delay discounting risky decision-making. The ventromedial prefrontal cortex (vmPFC) dorsolateral (dlPFC) are two distinct cortical areas that involved processing. Methods: Twenty children received transcranial direct current stimulation (tDCS) three separate sessions one of montages each, including anodal/cathodal tDCS over the left dlPFC right vmPFC respectively, reversed montage, a sham...
Abstract Dysfunctions in bottom‐up emotion processing (EP), as well top‐down regulation (ER) are prominent features pathophysiology of major depressive disorder (MDD). Nonetheless, it is not clear whether EP‐ and ER‐related areas regionally and/or connectively disturbed MDD. In addition, yet to be known how interactively linked regulatory behavior, this interaction disrupted our study, regional amplitude low frequency fluctuations (ALFF) whole‐brain functional connectivity (FC)...
Abstract Theory of mind (ToM) is the ability to attribute subjective mental states oneself and others significantly impaired in autism spectrum disorder (ASD). A frontal‐posterior network regions including ventromedial prefrontal cortex (vmPFC) temporoparietal junction (TPJ) involved ToM. Previous studies show an underactivation these ASD. Transcranial direct current stimulation (tDCS) a noninvasive brain method for causally investigating brain‐behavior relationships via induction cortical...
