Research Abstract |
The purpose of this study is to investigate neural mechanisms of the audio feedback control of vocalization using the horseshoe bat as a model animal. Single unit recordings and pharmacological manipulation of the neural activities in nucleus ambiguus(NA) were conducted while the subject animals were controlling their frequency and temporal parameters of vocalization depend on the auditory feedback of their echo. Results show that regions where the drug injections can affect the fernery and temporal aspect of vocalization are anatomically segregated, and all frequency correlated units in NA received GABAergic control.
