Conduction velocities (m/s) of axons of reticulospinal neurons

	M-cell	MiD2 cm	MiD3 cm	MiM1D	MiM1V	MiD2i	MiD3i	MiV1	MiV2	MiV3
Mean	117.3	48.3	52.4	44.7	47.6	50.7	47.5	44.8	51.2	39.1
SEM	3.2	1.4	1.5	3.8	2.9	0.9	1.5	2.6	1.2	1.0
n	45	22	28	10	11	56	22	10	27	20

Values were calculated from the onset latency of the antidromic AP and the distance between the spinal stimulus site and the recording site in the hindbrain.
