The Effect of Transcranial Direct Current Stimulation on Human Brains: A Neuroimaging Study
Completed · Not applicable · Has a placebo group
Conditions studied: Chronic Schizophrenia
In brief
The purpose of this project is to examine brain function before, during, and after the administration of tDCS (Transcranial Direct Current Stimulation). The brain can perform its job well or poorly depending on many things. The investigators will be using computer tasks and paper and pencil questionnaires to measure the relationship between brain performance and the administration of tDCS. In addition, the study team will be using functional magnetic resonance imaging (fMRI) and related imaging techniques to see how your brain works and compare it with the results we collected from the paper and pencil questionnaires. This study will enroll both schizophrenia patients as well as healthy volunteers without any major psychiatric disorder or physical illness.
