Brain Criticality, Oculomotor Control, and Cognitive Effort

"The study intervention involves modulation of cortical excitation to inhibition (E/I) balance in the right frontal eye field (FEF) by means of 2 trains of spaced continuous or intermittent theta burst stimulation (cTBS, iTBS, respectively) using a transcranial magnetic stimulation device. The endpoint of this stimulation will be a decrease (cTBS) or increase (iTBS) in the local E/I ratio that should last at least 60 minutes post-stimulation (Chung et al., 2016).~In separate sessions, all participants will receive either active or stimulation to the FEF. The Investigators will contrast the effects of both iTBS and cTBS to sham stimulation and to each other."
