The purpose of this study is to examine whether cerebellar stimulation can be used to improve cognitive deficits and mood in patients with schizophrenia, autism, bipolar disorder, Parkinson's disease, and major depression.
Our recent work found that patients with Parkinson's disease and schizophrenia have impaired frontal EEG rhythms in the theta and delta range (1-8 Hz).We have been using transcranial direct current stimulation to recover these rhythms as patients perform elementary cognitive tasks. We found that although we are able to modulate cerebellar and frontal activity with tDCS, this effect is minimal as the depth of the current is not great enough to modulate all cerebellar activity. Here we use transcranial magnetic stimulation (TMS) to modulate neural activity in the frontal cortex and recover cogni…

Subjects with neuropsychiatric diagnoses and matched-controls will be receive theta frequency stimulation of the cerebellum. We will target the cerebellar vermis.
Subjects with neuropsychiatric diagnoses and matched-controls will be receive sham stimulation of the cerebellum. We will target the cerebellar vermis.
