< .001). Other frequency band changes (beta, alpha) showed drug effects in analysis of variance but lacked consistent post hoc support. The increase in gamma power and alteration in aperiodic slope suggest engagement of cortical network mechanisms consistent with restored excitation/inhibition balance and enhanced neural synchrony. These preliminary neurophysiological findings support the possibility that electroencephalography-based measures could serve as objective biomarkers for lithium's neural effects in individuals at high suicide risk and warrant further large-scale studies integrating behavior and neurochemistry.
