- Аннотация: The acoustic responses of cells in the basal forebrain were studied in the adult waking guinea pig. Frequency receptive fields were obtained across wide frequency (0.094 - 45.0 kHz) and intensity (0 - 90 dB) ranges. A total of 326 recordings were obtained in 26 electrode penetrations from 5 subjects; 205 from the globus pallidus (GP), 98 from the caudate-putamen (CPu) and 23 from the central nu-cleus of the amygdala (ACE). Twenty-nine recordings exhibited acoustic responses (GP = 20 (9.8%); CPu = 9 (9.2%); ACE = 0). Cells in the regions of the GP that project to the primary auditory cortex (ACx) exhibited frequency tuning that was dominantly suppressive. Responses in the CPu were excita-tory, but poorly tuned. The spontaneous rate of discharge of GP cells that yielded complete tuning data was positively correlated with power in the beta bands (12-25 and 25-50 Hz) and negatively correlated with power in the delta band (1-4 Hz) of the EEG of the ACx. These findings suggest that acoustically tuned neurons in the GP, that are inhibited by tones, are involved in the regulation of auditory cortical state, possibly promoting deactivation to unimportant sounds, and may be cholinergic in nature.
