[The corticorubral projection in rats: topographic distribution of fibers arising from areas of the sensorimotor cortex functionally identified by microstimulation].
The combination of microstimulation and anterograde tracing techniques reveals that different regions of the sensorimotor cortex project to different sectors of the red nucleus (NR). V-FEF projects to the dorsolateral sector, JLT to the dorsal sector, RFL and CFL to the dorsomedial and medial sectors, respectively, and HL to the ventral and ventrolateral sectors. Moreover, the NR receives fibers from the 2 somatosensory cortical areas examined in this study. The vibrissae area projects to the dorsolateral sector and the hand area to the dorsomedial sector.
