Trial	Description
Pulse alone trials	20 msec in duration of 120 dB intensity white-noise.
Prepulse trials	20 msec prepulses of 73 dB, 76 dB and 82 dB intensities.
Prepulse–pulse trials	20 msec prepulses (73 dB, 76 dB and 82 dB) presented before the onset of pulse-alone stimuli.
NOSTIM trials	No stimuli, but mouse movements are recorded as a measure of basal motor activity in the cylinder.
