TL;DR
The authors postulate that the observed response decrement may be a form of habituation, which provides a model for studying the neuronal substrates of behavior.
Abstract
In normal subjects, cerebral potentials were evoked by brief, passive extension of the wrist joint at various interstimulus intervals (ISIs). The resulting somatosensory evoked potentials (SEPs) were found to decrease during repetitive stimulation. The greatest decrement occurred between the first and second responses of each series. After cessation of stimuli, the SEP amplitude returned to control values over a prolonged, exponential time course. The authors postulate that the observed response decrement may be a form of habituation, which provides a model for studying the neuronal substrates of behavior.

Responses were obtained when an unpredictable pitch change was presented in an effort to elicit dishabituation and a large positive component with a peak latency of about 300 msec was seen as reflecting a shift of attention associated with the orienting response.

Detailed clinical sensory and motor signs were correlated case by case with somatosensory evoked potentials (SEP) in 22 selected patients with a single circumscribed hemisphere lesion, suggesting collateral reinnervation by residual inputs after partial deafferentiation of prerolandic cortex.

The results show that human vertex response satisfies several main characteristics of habituation, and follows approximately a negative exponential function of the number of stimulus presentations.
The Journal of the Acoustical Society of AmericaEffect of Changes in Stimulus Frequency and Intensity on Habituation of the Human Vertex Potential
245 Citations1968Robert A. Butler
The notion that changes in stimulus frequency and increases in stimulus intensity activate new neural units was adopted to explain the data and it was asserted that habituation of the V potential is greatest when the same neural units are repeatedly activated and least when new Neural Unit brought into play.
Electroencephalography and Clinical NeurophysiologyHabituation and dishabituation of the human vertex response
134 Citations1971H. Fruhstorfer
The hypothesis that the vertex response is mediated by an extralemniscal system is supported, on the assumption that auditory and somatosensory information converge in a subcortical centre and ascend in a common corticipetal pathway.

Antidromic latency and threshold shifts were observed in somatosensory callosal axons and in some corticotectal axons, and the duration of the latency decrease was greater for slowly conducting axons than for fast conducting axon.

Evidence is provided that evoked potentials can be used as electrophysiological indexes of plasticity in humans according to the parametric characteristics of habituation, generalization, and dishabituation.

105 Citations1980H. Shibasaki, Geoff Barrett +2 more
Average cortical potentials associated with voluntary and passive movements were compared mainly with respect to their scalp topography and it is postulated that these components may be the projected potential fields from a dipole source within the central sulcus and may represent a kinesthetic feedback from the muscle afferents.

It is concluded that information about muscle stretch arising from muscle mechanoreceptors reaches the cerebral hemispheres of man at short latency and that the resulting potentials can be readily detected using scalp electrodes.

The findings suggest that stimulus rates of up to 8/sec can be used without significant loss in detectability of most of the components and with a larger number of synapses leading to the generators of the later components than to earlier ones.

Following the relative refractory period of a single prior impulse, all but one of 61 callosal efferent neurons studied showed a supernormal period of increased axonal conduction velocity and excitability, which, depending on the number of prior impulses, lasted from several hundred ms to nearly 2 min.

The literature has been reviewed by Gorton (1949) and Barber (1961), but this work and some other papers have added little to the authors' understanding of the mode of action of hypnotic suggestion in producing a loss of sensibility, although they substantiate the existence of differences in the objective responses to 'painful' stimulation in the hypnotic state.

This study replicates the ‘fast’ habituation of the auditory vertex potential over the course of a train of repetitive stimuli using visual stimuli, finding it to be well-evidenced at a vertex recording site, but less well at a more posterior derivation.

33 Citations1973Robert A. Butler
Response latencies were reduced when the test stimulus was preceded by slowly and periodically presented stimuli compared to those recorded when no stimuli intervened between successive test stimuli, interpreted to mean that the intervening stimuli “alerted” the auditory nervous system to the impending arrival of the test stimuli.

It was found that the first flash of a stimulus train produces the largest response both at the retina and the occipital scalp; then there is an immediate reduction in amplitude followed by some recovery.

The goal of the present experiment was to rule out the hypothesis that evoked potential (EP) decrements during repetitive stimulation are due to a change in the subject's state; i.e., that the decrements are part of general, nonselective, non-specific, state-related decrement in all EPs.
