Escape latency is expressed as mean ± s.e.m. (in seconds, s). Pain threshold in infant rats was measured by the escape latency to withdrawal from a 53 ± 1°C hotplate. The escape latency was averaged from four sessions, with an inter-session interval of 15-min. Student’s t-test revealed no significant difference between PN17 (10.1±0.8 seconds, n=6) and PN24 rats (8.2±0.9 seconds, n=6) (two-tailed t test, t =1.562, df=10, P=0.7028).
