Figure 4: The effects of gabazine on thresholds and bandwidths of auditory tuning curves (population data). (a) Blockade of inhibition by gabazine decreased thresholds in both normal and XMAC. (b) The threshold changes in XMAC were not significantly different from those in the normal AC. (c) Blockade of inhibition by gabazine increased bandwidths in both normal and XMAC. (d) The changes in bandwidth in XMAC were significantly greater than those in the normal AC. ; ; .
