Figure 3

Superposition of high-power photographs of a transverse section through the y-group showing premotor tracer-labeled neurons (green, arrowhead), some of which contain CR (orange, solid arrow). Not all CR-positive neurons are tracer labeled (red, thin arrow; A). Photographs of corresponding sections through the vestibular nuclei of monkey stained for retrograde tracer WGA (black cells; B) or CR (brown cells; C). Note that MVNm contains numerous tracer-labeled neurons (arrow; B), but few CR-positive neurons (arrow; C). The vestibular nerve (NVIII) contains numerous CR-positive fibers (solid arrows). Transverse sections through the vestibular nuclei of a monkey with a tracer (CTB) injection into the right oculomotor nucleus with the retrogradely labeled neurons plotted (black dots; D, E). Tracer-labeled CR-positive neurons (red dots) are mainly found in the y-group of both sides (D). Putative excitatory secondary vestibulo-ocular neurons in the left MVm lack CR (E), but they are contacted by numerous large CR-positive terminals (red, arrows; F, G).
