TABLE 2.

Comparison of latencies in Sg and IC

	Sg	ICXv	ICC^*
Median, ms	11.3	6.0	9.5
Interquartile range	10.2	1.0	3.9
Mean, ms	12.8	6.1	9.5
95% Confidence interval	4.6	0.4	2.4
Range	4.9–25.7	4.8–10.0	6.0–18.0
n	30	60	22

Median first-spike latency for 30-ms best excitatory frequency (BEF) tones, 20–30 dB above minimum threshold. ICXv, ventral division of the external nucleus of the inferior colliculus; IC, inferior colliculus; ICC, central nucleus of the IC.

Units recorded primarily in the anterolateral division of ICC, which represents frequencies below CF2.
