An underestimated visual pathway in reptiles
Neuroscience Letters, 1985Field potentials evoked in the turtle general cortex by electric stimulation of the optic tectum were analyzed. Cathodal polarization and subtotal lesions of n. rotundus led to either facilitation or depression of later components of the cortical potential. On the contrary, cathodal polarization and lesions of n.geniculatus lateralis dorsalis similarly

Computed tomography (CT) and magnetic resonance imaging (MRI) are excellent imaging modalities that have significantly enhanced orbital imaging in the diagnosis of ocular and orbital lesions. CT is excellent in the evaluation of the bony orbit and is the imaging modality of choice for most trauma situations. One of the most important roles played by CT

A MODEL OF THE VISUAL PATHWAYS
Archives of Ophthalmology, 1942It is the purpose of this communication to describe a model of the visual pathways which was constructed in conjunction with Dr. David G. Cogan and used in the graduate course in ophthalmology at the Harvard Medical School. While brain modeling is a well established procedure in neurologic teaching, it appears to have been used relatively little in ...

The object of this paper is to give the present state of knowledge concerning the central visual pathways, the geniculocalcarine tract as well as the visual cortex. So much has been accomplished in this field within the last two decades that it seems justifiable to make a survey of all of the material that has been published in connection with the ...

Hyperacuity and interpolation by the visual pathways
Vision Research, 1982Abstract Hyperacuity demands some form of neural interpolation. This places constraints on the relation between optical image quality and the cone mosaic. In particular, if the cone mosaic significantly undersamples the optical image, then hyperacuity is downgraded.

A tectocortical visual pathway in the rat
Neuroscience, 1980Abstract Injections of tritiated leucine into the superior colliculus of the rat were used to study the efferents of the colliculus. The superficial layers of the colliculus project to the lateral posterior nucleus, the lateral geniculate nucleus and the pretectum.
