Rod Driven Frequency Entrainment and Resonance Phenomena

open access: yesFrontiers in Human Neuroscience, 2016
A controversy exists on photic driving in the human visual cortex evoked by intermittent photic stimulation. Frequency entrainment and resonance phenomena are reported for frequencies higher than 12 Hz in some studies while missing in others.

Closed-loop photic stimulation using EEG

open access: yes, 2020
Accumulating evidence indicates that neural oscillations play a central role in brain function, organising and modulating brain activity in response to both bottom-up exogenous stimuli and top-down endogenous dynamics.
