Processing of acoustic signals by cerebellar neurones of the big brown bats, Eptesicus fuscus

摘要: The cerebellum of a vertebrate not only receives signals from the motor areas cerebral cortex but also different impulses indirectly almost all sensory receptors. With Eptesicus fuscus, we studied response properties cerebellar neurones to acoustic stimuli (40 ms duration, 0.5 rise‐decay time). Single responding auditory could be isolated rather large bat's vermis and hemispheres. They were usually spontaneously inactive discharged either tonically or phasically. These units had latencies between 4 13 best frequencies 22 77 kHz. Q10‐dB values their triangular tuning curves 1.4 16.6 with majority below 10. Minimum thresholds 12 65 dB SPL. When delivered through earphones, measured each ear alone nearly identical in shape frequency. At present, do know whether exclusi...
