Table 2. Numbers of neurons recorded in pentobarbital-application experiments.

A total of 61 rats (number of rats per age is indicated in the top row under the age header) were used for pentobarbital application experiments to record spontaneous action potentials from 1,118 neurons. The distribution of neuronal recordings is shown for each age and region.

	P10 (n=6)	P11 (n=7)	P12 (n=8)	P13 (n=10)	P14 (n=11)	P15 (n=10)	P20 (n=9)
PBC-region neurons	24	37	31	39	45	31	51
XII motoneurons	41	32	26	36	38	97	46
NTS neurons	34	28	38	47	40	40	31
Cortical neurons	47	56	38	35	24	42	44
