| Summary, etc | Auditory temporal integration (ATI) has been widely described in psychoacoustic studies, especially for loudness<br/>perception. Loudness increases with increasing sound duration for durations up to a time constant about 100 ~ 200 ms, and<br/>then loudness becomes saturated with more duration increase. However, the electrophysiological mechanism underlying the<br/>ATI phenomenon has not been well understood. To investigate ATI at the brainstem level of auditory system and its<br/>relationship to cortical and behavioral ATI, frequency follow response (FFR) was acquired in our study. Simultaneously, ATI<br/>in auditory cortex was evaluated by cortical response P1. Behavioral loudness and electrophysiological measures were<br/>estimated from normal-hearing young adults for vowel /a/ whose durations varied from 50 ms to 175 ms. Significant effects<br/>of stimulus duration were found both on FFR and P1 amplitudes. Linear regression analysis revealed that as stimulus<br/>duration increased, brainstem FFR amplitude was significantly associated with cortical P1 amplitude and behavioral loudness,<br/>which confirmed the existence of temporal integration in auditory brainstem. Moreover, behavioral loudness ATI was better<br/>predicted using brainstem and cortical measures together than merely using each one separately, indicating an interplay and<br/>coordination for ATI across the three levels along auditory pathway. |
