title: Intrinsic properties of identified neurones in the central nucleus of mouse inferior colliculus.
abstract: The intrinsic properties of morphologically identified neurones in the central nucleus of the inferior colliculus (ICC) were investigated using a mouse brain slice preparation. Thirty-four neurones were physiologically characterized and classified into three response types: onset, intermediate and sustained. Thirteen were stained intracellularly and appeared to be multipolar cells spanning several fibrodendritic laminae of the ICC with their dendritic trees. Onset-type neurones showed only a small afterhyperpolarization and often a rectification to depolarizing current pulses. Thus, the suggestion is put forward that onset-type cells are especially well suited for coincidence detection of incoming auditory stimuli over a broad range of frequencies, whereas sustained-type neurones may perform different tasks in integrating and regulating the auditory input to the ICC.
