title: [Relationship between interaural phase difference and the response of neurons in the frog midbrain hearing center].
abstract: Many binaural neurons within the torus semicircularis of the lake frog are cyclically responsive to the interaural phase angles of a sinusoidal stimulus at frequencies up to approximately 1.2 kHz. In the range of small interaural delays, the neurons increase their reactions when the contralateral stimulus leads. The 20 mcsec delay of the contralateral tone can elicit a considerable drop in spike generation probability. The "characteristic" delay occurs outside the range of interaural delays the frog could naturally encounter. Some other neurons responding both to contralateral and ipsilateral stimuli discharge minimally when there is no interaural delay. The variety of discharge patterns can be elicited from a single neuron by alteration of the interaural delay.
