Binocular responses in the superior colliculus of the albino rat. 1984

The retinotopic map for the contralateral eye is similar to that found in the pigmented rats and in other rodents. Cells which had ipsilateral responses were recorded in a fairly large area in the rostral portion of the tectum. Their receptive fields lay from about 40 degrees in the contralateral hemifield to about 40 degrees in the ipsilateral hemifield. The ipsilateral response of a binocular cell is similar in almost every respect to its counterpart in the opposite eye except being very weak and that the receptive field is usually smaller. Most binocular cells are distributed in the Stratum griseum superficiale (SGS) and the Stratum opticum (SO). Less binocular cells recorded in the Stratum griseum intermediale (SGI) have more scattered distribution both in the size and in the position of the receptive field.

UI MeSH Term Description Entries
D003315 Cornea The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed) Corneas
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
