Aim: Decision-making is part of the cognitive control that plays a key role in the evaluation of desires. The present study was performed to investigate the effects of tDCS on the left hemisphere DLPFC brain region in high-risk decision making and risk-taking. Method: The study was a single-blind experimental study performed on 30 healthy adults. In this study, subjects were randomly divided into two experimental and sham groups. In the experimental group, anodal stimulation over the right hemisphere OFC and cathodal stimulation over the left DLPFC was performed at 2 mA. The tasks used were computer versions of Balloon Analogue Risk Task(BART) and Iowa Gambling Task(IGT) for evaluating high-risk decision making and risk-taking. Data were analyzed using a one-way ANCOVA test. Results: Results showed a significant difference between the experimental and control groups in the Bart test(P

Aim: :executive function is a multidimensional system with multiple processing that is damaged in bipolar patients. Therefore, the purpose of this study is to compare the executive function of bipolar I patients who received rehabilitation for 5 years and normal subjects.Method:The present study is a comparative causal study that was performed on two groups of 30 patients with bipolar I disorder who underwent rehabilitation therapy from year 1391 and a group of normal subjects who were matched to bipolar patients. The tools used were the computerized version of the Wisconsin Test and Tower of London. Data were analyzed using MANOVA Multivariate Analysis.Findings:The results showed that there is a significant difference between the two groups in the executive functions (F (8, 21) = 20/66 & P2 =0/88) Conclusion:Based on the results, although patients have undergone several rehabilitation therapy courses for several years, their cognitive impairments have remained stable.
