A, left panel, DiI fluorescence image of a L6 spinal cord slice from a P9 female rat, which received a bilateral DiI injection into the ischiorectal fossa a few days before the dissection. Right panel, near IR-DIC image of a cluster of DLN motoneurons. B, representative current-clamp recordings from DLN, VN and RDLN motoneurons. Injected current traces are shown below. C, resting membrane potentials of the motoneurons.D, input resistances of the motoneurons. E, firing thresholds of the motoneurons. F, rheobase of the motoneurons. G, firing frequency-current (f-I) relationships of the motoneurons. H, scatter plot of resting membrane potentials as a function of rheobase of individual DLN, VN and RDLN motoneurons. I, scatter plot of input resistance as a function of rheobase of individual DLN, VN and RDLN motoneurons. DLN = 26 cells/4 animals, VN = 13 cells/6 animals, RDLN = 13 cells/5 animals. ***P |
