Comparison of the response characters in different subregions in the IC. Individual metrics of the response to sound compared among the subregions in the IC. A, Threshold, GABA (black); n = 18, n = 13, n = 15, and n = 12 for Area 1, border, Area 2, and cortex, respectively. The order of the numbers for the different regions is the same in the subsequent descriptions. GLU (red); n = 32, n = 14, n = 14, and n = 23. B, Latency, GABA; n = 17, n = 16, n = 22, and n = 12. GLU; n = 31, n = 17, n = 24, and n = 22. C, Maximum rate, GABA; n = 15, n = 6, n = 14, and n = 10. GLU; n = 31, n = 14, n = 15, and n = 20. D, BW10, GABA; n = 15, n = 6, n = 14, and n = 10. GLU; n = 31, n = 14, n = 15, and n = 20. E, BW40, GABA; n = 12, n = 6, n = 9, and n = 6. GLU; n = 14, n = 9, n = 8, and n = 15. F, BWI10, GABA; n = 15, n = 6, n = 13, and n = 10. GLU; n = 31, n = 14, n = 15, and n = 20. G, BWI40, GABA; n = 12, n = 6, n = 9, and n = 6. GLU; n = 14, n = 9, n = 8, and n = 15. H, The highest modulation frequency with synchronization to SAM (left, GABA; n = 13, n = 6, n = 11, and n = 9. GLU; n = 19, n = 8, n = 8, and n = 14) and raised sine (right, GABA; n = 13, n = 7, n = 11, and n = 9. GLU; n = 18, n = 8, n = 7, and n = 14). The numbers in the figures indicate the number of data in each bar. C, E, The parameters were significantly different among the regions, but not between cell types: *p < 0.05; **p < 0.01.
