Inhibitory stimulus definition

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.
