[Reflection of space characteristics of an acoustic signal in the neuronal activity of the caudate nucleus].
In chronic experiment, responses of single neurons of the caudate nucleus (CN) to spatial characteristics of acoustic signal have been investigated in dogs. It is shown that 92% of neurons of the caudate nucleus' head responding to sound stimulation asymmetrically react to contra- and ipsilateral monoaural, with a greater efficacy of a contralateral stimulation. For 50% of the CN neurons simultaneous sound inputs appear more effective in comparison with contralateral stimulation. 77% of the caudate neurons responding to sound have shown sensitivity to change of the value and sign of the interaural delay.
