Single unit study in the inferior colliculus of the house mouse (Mus musculus).
Auditory responses of single units in the central nucleus of the mouse's inferior colliculus with a range of best frequencies of 5-50 kHz were studied electrophysiologically. The threshold values to tone burst stimulation of the most sensitive units were in good agreement with a behavioral audiogram measured on animals of the same strain. The unit's best frequencies showed the same vertical tonotopic organization as in the inferior colliculus of other mammals. Most units responded only to the onset of the stimulus.
