Oscillatory Activity in Visual Processing

This lecture explores the implementation of visual processing through oscillatory activity, focusing on Granger causal influence, bar touch, fixation, stimuli onset, and frequency changes. It delves into entraining oscillatory activity by transcranial Alternating Current Stimulation (tACS) to support inter-areal communication and visual awareness. The lecture also covers the effects of bifocal tACS during motion discrimination, including behaviorally disruptive and optimal phase lags. Additionally, it discusses the application of Non-Invasive Brain Stimulation (NIBS) to enhance cognitive performance in healthy subjects, such as memorization and arithmetic training. The lecture concludes with a summary of NIBS techniques, including Transcranial Magnetic Stimulation (TMS) basics and mechanisms, as well as the clinical applications and limitations of NIBS.
