The waveform of evoked responses recorded from human scalp is not determined solely by the physical eliciting stimulus, but also varies as a function of the effective information provided by the stimulus. There is a positive component whose latency is determined by the point in time at which ambiguity is reduced, and whose shape and amplitude are influenced by whether it is the presence or absence of an external event which delivers the information. 

The Endogenous Evoked Potentials

This paper reviews some “endogenous” potentials that can be recorded from the human scalp in relation to the processing of sensory stimuli into behavioral responses. Twenty years ago, Sutton et al.

Visual evoked and emitted potentials and stimulus significance

Sutton et al (1967) found that an emitted potential would occur in the absence of an auditory stimulus when the absence provided significant information. This result is extended to visual stimuli and

Average evoked potentials and uncertainty resolution

Two Ss were presented with a series of near threshold flashes of light and instructed to report for each flash in which of eight different positions it appeared, and the degree to which they were

Endogenous late positive component of the evoked potential in cats corresponding to P300 in humans.

A long-latency component of the averaged evoked potential recorded from cats was present only when the evoking stimulus was relevant to the task and was independent of stimulus modality.

Evoked Potential Correlates of Auditory Signal Detection

A long-latency comnponent of the averaged evoked potential recorded from the human scalp varied in close relationship with subjects' perceptual reports in an auditory signal detection task. Detected

Averaged Evoked Responses in Vigilance and Discrimination: A Reassessment

The data suggest that the late positive component represents cerebral processes associated with evaluation of unpredictable changes in stimulation in the context of vigilance tasks.

Cortical potentials associated with the detection of visual events.

A positive-going potential, which reaches a maximum at the vertex and midline parietal scalp electrodes, occurs in the human being when an infrequent, significant event occurs in a continuously



Evoked-Potential Correlates of Stimulus Uncertainty

The average evoked-potential waveforms to sound and light stimuli recorded from scalp in awake human subjects show differences as a function of the subject's degree of uncertainty with respect to the

Enhancement of Evoked Cortical Potentials in Humans Related to a Task Requiring a Decision

The averaged, slow response evoked by auditory stimuli and recorded from the vertex of the human skull can usually be enhanced by requiring the listener to make a rather difficult auditory

Attention, Vigilance, and Cortical Evoked-Potentials in Humans

Computer-averaged potentials evoked from the cortex were recorded to nonsignal stimuli and to randomly interspersed signal stimuli requiring detection and response during prolonged visual vigilance.


The study of potentials evoked at cortical sites in response to stimulation of deep brain regions has contributed to the understanding of cortical-subcortical relations.
