Retinal projections in the hagfish, Eptatretus burgeri.
The retinal projections of hagfish were investigated by anterograde transport of HRP and the Nauta-Gygax method. The pathway coincided with the commissura postoptica of Jansen after complete crossing within the hypothalamus. Many projections were found in the contralateral 'area pretectalis', but there were only a few projections in the tectum mesencephali, the pars ventralis thalami, and the n. tuberculi posterioris of Jansen.
