Electrophysiological studies on the effect of rhythmical sound on the recruiting response

, : Electrophysiological studies on the effect of rhythmical sound on the recruiting response. Journal of the Kansai Medical University 37(1): 7-16

As a part of the study to elucidate the influence of rhythmical sound on the CNN activity, the effect on the recruiting response of rabbits was investigated and the following observed. The recruiting response in the cerebral cortex EEG induced by 8 Hz stimulation of the nucleus ventralis anterior (VA) or the nucleus reticularis (RET) was facilitated by the rhythmical sound of 60/min or 120/min beat frequency and 500 Hz pitch. The recruiting response induced by 8 Hz stimulation of VA or RET was inhibited by the rhythmical sound of 450/min and 1000 Hz. The rate of change in the amplitude of this recruiting response by sonic stimulation was analyzed quantitatively by determination of the wave pattern, using the digital computer (ATAC-201). With a sonic stimulation of 60/min or 120/min and 500 Hz, there was an increase in amplitude of the recruiting response of an average of +61% while with 450/min and 1000 Hz an average decrease of -30% was noted. These results suggest that the previously reported decrease in excitability of the brain stem reticular formation (RF) by rhythmical sound of a low frequency and low pitch and the increase in excitability of RF by the rhythmical sound of a high frequency and high pitch can be attributed to a rise in indirect inhibition and a decrease in indirect inhibition, respectively, via the diffuse thalamocortical projection system.
