Cognitive evoked potentials



Français English

A type of evoked endogenous potentials linked to a subject’s reaction during sensory stimulation. A mental and/or motor task is to be performed by the subject every time the stimulation is given. The cognitive evoked potentials are distinguished from classic exogenous evoked potentials, which are due to external stimuli. Evoked potentials are brief changes in the electroencephalographic signals produced in response to a distinct sensory stimulus.
