  • Title: Segregation of optic axons based on central target: the medial optic tract in Rana pipiens.
    Author: Montgomery NM, Fite KV, Li Z.
    Journal: Neurosci Lett; 1995 Aug 11; 195(3):199-202. PubMed ID: 8584209.
    Abstract:
    The retinofugal projection to the nucleus of Bellonci (nB) was examined in Rana pipiens using both anterograde and retrograde transport of horseradish peroxidase (HRP). Following HRP injection into the nB, retrogradely labeled optic axons formed a discrete fascicle that crossed the lateral margin of the anterior diencephalon. We have designated this branch of the retinofugal pathway as the "medial optic tract." HRP-positive, medial optic tract axons projecting to nB occupied the rostral and most dorsal portion of the optic chiasm. The present findings indicate that within the optic chiasm, retinal axons are sorted according to their final destinations.
