Summary of discharge rates obtained from neonates in the present study (mean rate = 3.08 +/− 8.2 sp/s, n = 48). The graph reflects the spike rate (sp/s) distribution as a function of neonatal age in days post-conception (dpc). Days 69 to 75 dpc correspond approximately to P3 to P9 postnatal days in the present study. Forty-eight neurons are represented. The one outlier at 56 sp/s was obtained from a very short record of 6 seconds and thus may not well represent the general spike rate of the cell. Mean recording duration for the group of neurons was ~151 seconds. Horizontal lines labeled A., B. and C. reflect mean spike rates reported by Romand (1984) for the adult cat (A. => ~ 45 sp/s), one month-old kitten (B. => ~ 27 sp/s) and 6 day kitten (C. ~ 4 sp/s).
