About the study
The purpose of this research is to better understand how emotion processing unfolds in the brain using stereoelectroencephalography (sEEG) and direct brain stimulation. This study will use standard behavioral emotion processing tasks combined with neural recording and direct brain stimulation to assess different aspects of emotion processing. Stimulation pulses during pre and post-test periods will assess the effects of stimulation before and after conditioning, the results of which will be combined with results from the activity of each electrode during the emotion tasks to inform us of the nature of emotion processing in the brain and allow us to devise brain modulation protocols in the future.
