[Changes in the nuclear volume of the receptor cells of the saccular macula in the frog Rana temporaria during sound exposure].

Sonic stimulation at a frequency of 1200 Hz increases nuclear volume in the upper part of the maculae by 30-45%, whereas after stimulation at a frequency of 250 Hz nuclear changes (30-38%) were noted mainly in the caudal parts. The auditory function of the sacculus in amphibians is confirmed and special attention is paid to functional heterogeneity of the receptor epithelium in the saccular maculae.
