Projections from the pontine reticular formation to the lateral geniculate body: Autoradiographic demonstration of a pathway that could mediate pontine-geniculate-occipital waves

Autoradiographic studies have revealed a pathway that may mediate pontinegeniculate-occipital waves. The projection originates in the rostral pontine tegmentum. Axons course rostrally through the midbrain and zona incerta, and turn ventrally at the level of the optic chiasm. Some axons cross the midline through the supraoptic commissure. The axons then travel caudally, just dorsal-medial to the optic tract, and appear to terminate bilaterally in the dorsal lateral geniculate nucleus.
