Figure 5

Effects of prepulses of a subtle sound decrease and sound frequency change on auditory Change-N1m. Test-evoked and Prepulse-evoked responses in all the three subjects (Subject 1 ~ 3) tested. The test response was elicited by an abrupt increase of sound pressure by 5 dB like in Experiment 1 and 2, while a brief sound with a weaker sound pressure (3 dB) or a higher sound frequency (2%) than the background was used as the prepulse. Note the very weak Prepulse-evoked response if present but clear reduction of the Test-evoked response.
