The Effectiveness of Transcranial Direct Current Stimulation(tDCS) from the Skull on Memory Students with Especially Learning Disorders

Introduction The purpose of this study was to determine the effect of electrical stimulation of the brain from the skull on the memory of students with special learning disorder. The present study was a semi-experimental pre-test-post-test with control group. To this end, the sample was selected through a sampling method from among students with learning disabilities who were eligible to participate in the study. Twenty people were selected and randomly divided into two experimental and control groups. The geometric image analysis of Andre-Ray (1942) was used to measure memory variables in the form of pre-test and post-test. The F3, F4 students in the experimental group were brainwashed in 10 sessions, while the control group students were only stimulated by the same conditions. The protocol in this study was a two-way stimulation of the left and right DLPFC area, which was performed in 2 15-minute intervals. In order to test the research hypothesis, in other words, generalization of the results of the sample to the statistical population of the study, one-way covariance analysis (ANCOVA) was used. The results showed that there was a significant difference between the two experimental and control groups in memory improvement (P
