Intracranial and epicranium recordings of the average evoked potentials in response to acoustic clicks were conducted using the hill mynah.<BR>Records under some experimental conditions and tests after monaural lesion show that these potentials are in fact brain stem auditory evoked potentials (BAEPs). A typical waveform of the mynahs'BAEPs is composed of a series of brief spike-like potentials with latencies of one to 4ms after stimulation. This BAEP pattern is similar to that extensively studied in mammals. In an immobilized bird the BAEP can be recorded by a small number of stimulus presentations because of the high S/N ratio.<BR>BAEP research promises significant contributions in the field of neuroethology and behavioral neurobiology since it can be carried out without injuring the brain. We believe that the BAEP may yield valuable data regarding the degree and recovery process of temporary hearing deficiencies resulting from an experimentally produced acoustic trauma in birds.
