A binaural neuron that showed a long-latency excitation to stimulation of either ear. A, Ipsilateral (IPSI) responses to two sequential tone bursts (1.5 kHz) reveals a late depolarization accompanied by a spike or two.B, Same stimulus as in A delivered to the contralateral (CONTRA) ear evoked a similar response.C–F (right column), Responses to binaural stimulation at the contralateral and ipsilateral levels indicated. Binaural responses systematically declined as the level to the ipsilateral ear was reduced until the response resembled the response to contralateral stimulation (F). Binaural responses were not tested at the same levels as the monaural responses.
