The steady-state visual evoked potential in vision research : a review [PDF]

open access: yes, 2015
Periodic visual stimulation and analysis of the resulting steady-state visual evoked potentials were first introduced over 80 years ago as a means to study visual sensation and perception. From the first single-channel recording of responses to modulated

Large Difference in Latency of Visual Evoked Potential P100 Peak in Case of Pattern and Flash Stimulation in a Multiple Sclerosis Patient [PDF]

open access: yes, 2021
The visual evoked potential is one of the suitable techniques for the diagnosis of multiple sclerosis. There are two stimulation techniques, i.e., pattern reversal checkerboard and flash, to record visually evoked potential.

On the stimulus duty cycle in steady state visual evoked potential [PDF]

open access: yes, 2014
Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly
