Noun1.cortical potential - (neurophysiology) rapid fluctuations of voltage between parts of the cerebral cortex that are detectable with an electroencephalograph
neurophysiology - the branch of neuroscience that studies the physiology of the nervous system
alpha rhythm, alpha wave - the normal brainwave in the electroencephalogram of a person who is awake but relaxed; occurs with a frequency of 8-12 hertz
beta rhythm, beta wave - the normal brainwave in the encephalogram of a person who is awake and alert; occurs with a frequency between 12 and 30 hertz
bioelectricity - electric phenomena in animals or plants
delta rhythm, delta wave - the normal brainwave in the encephalogram of a person in deep dreamless sleep; occurs with high voltage and low frequency (1 to 4 hertz)
theta rhythm, theta wave - the normal brainwave in the encephalogram of a person who is awake but relaxed and drowsy; occurs with low frequency and low amplitude

Infralow frequency training is not the only technique that relies on the slow cortical potential for training.
The patients' "thought power" was increased by raising the levels of cortical potential they had to generate to reach a goal box with the cursor.
She discusses the basic science, including the anatomy of hearing loss, principles of electrical stimulation of the auditory system, parts and functions of a cochlear implant, past and present devices, candidacy, and signal delivery with cochlear implants; nonphysiological objective measures, including electrode impedance, electrical field potentials, and averaged electrode voltages; and physiological measures: electrically evoked stapedial reflexes, compound action potentials, auditory brainstem response, auditory middle latency response, and auditory cortical potentials.
6) By three months, some infants show a preference (by behavioural observation such as PL) and demonstrate recognisable binocular cortical potentials.
