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
-
To observe changes in the startle response as the subject is exposed to an unexpected, sudden stimulus.
-
To observe changes in the startle response as the subject is exposed to the prepulse inhibition stimulus.
-
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.
Tasks Performed by the Student
Subject will:
-
put the headphones on and sit in front of the computer monitor displaying SuperLab,
-
relax and not move, and
- watch an .xpt presentation.
