FIGURE 4

Organization of lamprey octavolateral vestibular nuclei. Confocal image stack (top) showing retrogradely labeled vestibular neurons in three midbrain-projecting nuclei. Schematic diagram (bottom) of crossed and uncrossed vestibuloocular neurons in the anterior, inferior, posterior octavolateral nuclei (AON, ION, PON) projecting to motoneurons in the oculomotor (III), trochlear (IV), and abducens (ABD) nucleus. PON neurons (red lines) project to ABD Mns and the spinal cord (SC). Organizational scheme based on data reported by Gilland and Baker (1995) and Pombal et al. (1996). nV, trigeminal nerve; nPLL, posterior lateral line nerve; nVIII, vestibular nerve; MLF, medial longitudinal fasciculus.
