A projection from the parabigeminal nucleus to the pulvinar nucleus in Galago.
A projection from the parabigeminal nucleus (Pbg) to the striate-recipient zone of the pulvinar nucleus in the prosimian Galago was identified by anterograde and retrograde transport methods. In addition to the pulvinar nucleus, Pbg projections were found to terminate in layers 4 and 5 of the dorsal lateral geniculate nucleus and the central lateral nucleus. All three of these structures project to the superficial layers of the striate cortex. Similarities between the Pbg in mammals and the nucleus isthmi in nonmammals in connections and neurochemistry reinforce the idea that these two nuclei are homologous.
