Effects of long-term heat exposure on the auditory nerve-brainstem evoked responses

Abstract

1. 1.|The purpose of this study was to determine whether chronic latency changes were induced in the auditory nerve-brainstem potentials (ABR) during long-term heat exposure (acclimation). 2. 2.|Latency prolongations of the ABR were observed during acute (5 days) heat exposure. This was followed by a shortening of latencies and amplitude elevation after long-term (2 months) heat exposure (acclimation). 3. 3.|It was concluded that long-term exposure to heat induces chronic changes in nervous activity.
