Characteristics of bandwidths of inhibitory regions surrounding excitatory response areas in C57 units. A: Inhibitory bandwidth on the high side of CF versus CF. Forty-two units (63%) displayed inhibition at the high side of excitatory response areas. The inhibitory bandwidth was similar regardless of CF, although the units with the lowest CFs did have the biggest inhibitory bandwidths. B: As frequency representation in IC shifts in the C57 mouse, units with high CFs are located from mid to ventral regions of IC. We plotted inhibitory bandwidth versus depth to test whether high frequency units in ventral IC had smaller inhibitory bandwidths than dorsal high CF units. Inhibitory bandwidths on the high side of CF were similar across all recording depths. C: Inhibitory bandwidth on low frequency side of CF. Thirty-one units (46%) had inhibitory areas at the low frequency side of excitatory response maps. There was a positive correlation due to our inability to present frequencies below 6 kHz. D: Inhibitory bandwidths on the low side of CF were similar across all recording depths.
