Abstract
Topography of acoustic response characteristics in the auditory cortex (AC) of the Kunming (KM) mouse has been examined by using microelectrode record ing techniques. Based on best-frequency (BF) maps, both the primary auditor y field (AI) and the anterior auditory field (AAF) are tonotopically organi zed with a counter running frequency gradient. Within an isofrequency strip e, the width of the frequency-threshold curves of single neurons increases, and minimum threshold (MT) decreases towards more ventral locations. BFs i n Al and AAF range from 4 to 38 kHz. Auditory neurons with BFs above 40 kHz are located at the rostrodorsal part of the AC. The findings suggest that the KM mouse is a good model suitable for auditory research.
