Prepulse inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus (pulse), often using the startle reflex. The stimuli are usually acoustic, but tactile stimuli (e.g. via air puffs onto the … Visa mer The main three parts of the procedure are prepulse, startle stimulus, and startle reflex. Different prepulse-to-pulse intervals, or lead intervals, are used: 30, 60, 120, 240 and 480 ms. Lead interval counts from the start … Visa mer The magnitude of PPI is often significant, reaching as much as 65% in healthy subjects, with maximum inhibition is typically observed at 120 ms interval. The baseline startle … Visa mer Disruptions of PPI are studied in humans and many other species. The most studied are deficits of PPI in schizophrenia, although this disease is not the only one to be associated with … Visa mer Prepulse inhibition was first described in 1862 by Sechenov and was rediscovered at least twice before Howard S.

Stimulus control occurs when an operant (learned) behavior is emitted in the presence of certain appropriate antecedent stimuli and is not emitted when these stimuli are missing or other inappropriate stimuli are present.
