Study Summary
Low-frequency brain rhythms in the alpha (8-14Hz) and beta (15-29Hz) bands are strong predictors of perception and functional performance in a range of tasks, and are disrupted in several disease states. The purpose of this study is to investigate a direct causal relationship between low-frequency brain rhythms and sensory perception, and to optimize commonly used TMS paradigms to impact sensory processing and perception in a similar manner as endogenous rhythms. To do so, this study combines human magnetic resonance imaging (MRI), electroencephalography (EEG), non-invasive brain stimulation (transcranial magnetic stimulation; TMS), and biophysically principled computational neural modeling.
Primary Outcome
Participants receive one or zero tactile stimuli per trial and report detection or non-detection using a button press. Tactile stimuli are delivered at participants' individual perceptual threshold level (perceived roughly half the time). On a given trial, TMS may also be delivered 100 msec before the tap ('TMS100'), 25 msec after the tap ('TMS25'), or not at all ('TMS Null'), each for an equal number of trials. The 'hit rate' is defined as the number of trials with correctly detected tactile st
