Flash and pattern reversal stimulation failed to evoke clear cortical potentials, and electroretinograms were unrecordable.

The implants were successful in producing evoked cortical potentials in half of the animals tested.

Event-related cortical potentials (ERPs) have been used to assess whether a stimulus is consciously perceived or not.

Tinnitus and auditory evoked cortical potentials have also been studied.

The Bereitschaftspotential, movement-related cortical potentials.

In 1964, two movement related cortical potentials were discovered by Kornhuber and Deecke.

Neurofeedback monitors both slow and fast cortical potentials.

Fast cortical potentials range from 0.5 Hz to 100 Hz.

Fast cortical potentials can be described by their predominant frequencies, but also by whether they are synchronous or asynchronous wave forms.

Birbaumer and colleagues (1981) have studied feedback of slow cortical potentials since the late 1970s.
