Homeostatic Neural Responses to Photic Stimulation by Dr. Philipp Streicher

Abstract:
This talk presents findings from open and closed-loop neural stimulation experiments using EEG. Fixed-frequency (10 Hz) stimulation revealed cross-cortical alpha power suppression post-stimulation, modulated by the difference between the individual's alpha frequency and the stimulation frequency. Closed-loop stimulation demonstrated phase-dependent effects: trough stimulation enhanced lower alpha activity, while peak stimulation suppressed high alpha to beta activity. These findings provide evidence for homeostatic mechanisms in the brain's response to photic stimulation, with implications for neuromodulation applications.
