What this trial is about
This study investigates the ability of transcranial direct current stimulation (tDCS) applied over the motion processing area of the brain (area MT) to improve face emotion recognition (FER) ability. tDCS is a type of non-invasive brain stimulation in which low level currents are applied over the scalp to influence underlying brain function. In schizophrenia, impaired ability to detect facial motion has been shown to contribute to impaired FER, which, in turn, leads to difficulties in social cognition and poor social outcome. The study will use both fMRI and EEG to measure brain function while participants view moving dot and dynamic face stimuli. Analyses will compare changes in fMRI and EEG activity in individuals receiving active vs. sham stimulation.
