H31 Prepulse Inhibition

A startle response is a physiological response to an unexpected intense stimulus, such as a burst of loud noise or the slamming of a door. This stimulus is known as the startle-eliciting stimulus. Responses to the startle-eliciting stimulus include increases eye blinking, heart rate, skin conductance, and muscular responses.

Experimental Objectives

  1. To observe changes in the startle response as the subject is exposed to an unexpected, sudden stimulus.
  2. To observe changes in the startle response as the subject is exposed to the prepulse inhibition stimulus.
  3. To measure, compare, and correlate the response of blink magnitude, latency, and habituation rate as the subject is exposed to the startle-eliciting stimulus and the pre-pulse inhibition stimulus.
