P50 wave. The amount of attenuation in the neural response to the second of the two identical stimuli indexes the strength of the inhibitory pathway. This paradigm has been adapted as a …
Sensory gating - Wikipedia
Evidence of the gating can be seen in the P50 wave, occurring in the brain 50 ms after the click. Low values of the P50 wave indicate that sensory gating has occurred. High values of the P50 …

Feb 1, 2000 · Traumatic brain injury (TBI) can produce persistent attention and memory impairment that may in part be produced by impaired auditory sensory gating. The P50 evoked …
P50 Sensory Gating in Infants - PMC - PubMed Central (PMC)
An auditory stimulus elicits a consistent EEG-measured brain response; the response includes a wave which, in adults, occurs approximately 50 msec after the stimulus. Since the wave is in …
