Summary The activity of 93 medial geniculate body (MGB) neurons was examined in anesthetized cats in response to monaural and binaural click stimuli. Three types of reaction were found with single clicks: an initial discharge (latency: 6–30 msec); an initial and a late discharge (latency of late discharge: 0,5-4 sec), and only a late discharge. Under the conditions of lateralisation (interaural time or intensity difference of the binaurally applied stimuli) significant changes as of the initial as of the late discharge were found. Using sound signals simulating a moving sound source a number of neurons were found to react specifically to the direction of this movement. An assumption is made concerning the role of the late discharge for the fixation of information about position of a sound source in space.
