iTBS/fMRI Study of Apex Control
Florida State University
Summary
The objective of this study is to examine the effect of transcranial magnetic stimulation (TMS) on the prefrontal cortex and posterior parietal cortex.
Description
The Comprehensive Control Task (CCT) was designed to examine hierarchical control in a single, well-controlled factorial task. On each trial, participants view a letter surrounded by a colored shape at a particular screen location. Color cues the relevant feature, letter or location, for a block of trials. The first trial of a block requires a decision of whether the stimulus is the first position of a circular sequence (sequence start). Subsequent trials require a decision of whether the viewed stimulus follows the previous stimulus in a circular sequence (sequence 1-back). The letter sequenc…
