Abstract
Inferior colliculus (IC) is a center of integration for auditory processing, receiving inputs from ascending, descending and intrinsic connections. The 20% of all the IC neurons are GABAergic and thought to play an important role in sound feature detection of IC. However their activities in vivo have not been not elucidated. For investigating the activity characteristis of IC GABAergic neurons in vivo, we combined juxtacellular labeling with immunocytochemistry to reveal the electrophysiologically recorded neurons are GABAergic or not and analyzed the response properties to sound stimuli and morphological characteristics of the neurons identified as GABAergic, comparing them with those of non-GABAergic neurons.
