[Study of the mechanism of auditory adaptation by simultaneous recording of cortical auditory evoked potentials and cochlear microphonic potentials].
Auditory adaptation, apart from the effect of the neurotropic drugs, galanthamine, GABA and nanophyn on this adaptation, was examined in 35 rabbits exposed to white noise (90 dB, re 2.10(-5) Pa, 10 min) by concurrent recording of evoked potentials of the brain and microphonic potentials of the cochlea. The results suggest that the mechanism of auditory adaptation is determined by the processes that occur in the synapses of the auditory system central parts and is monitored by the sympathetic nervous system.
