A critical feature of this pathway is the topographic organization of the fibers that make up the afferent visual pathway. Knowledge of the anatomy and topography of the afferent visual pathway will aid recognition and localization of specific patterns of visual field defects....
Visual pathwayVascularizationPathophysiologyRetinaOptic nerveOptic chiasmOptic tractLateral geniculateOptic radiationStriate cortexVision is the primary sense in humans. There are approximatelyone million axons in the optic nerve, constituting almost 40%of the total number of axons in all cranial nerves. ...
The eyes act as the initial point of contact through which photons pass to access the visual pathway. The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the ...
both in ophthalmology and anatomy; it is easy to understand why a second edition has so soon been called for.The subject-matter apparent in the title is fully and generously covered, the bony orbit and the eyeball, the appendages and the musculature, the vessels and the visual pathway. Mr...

All second-year University of Otago medical students were invited to participate in this project. The incentive for participating were the benefits of learning and participating to interact with the MR and a guided multi-user learning experience of the visual pathway (part of their third-year curri...
In this chapter we provide an overview of the patterns of cerebral cortical and subcortical pathological changes that occur in the various dementias. When viewed in this manner, the dementias can be categorized into five major groups based on the topogra
There are also two superior colliculi which are part of the visual pathway. The four colliculi are collectively known as quadrigeminal bodies. The entire region is known as the tectum or tectal plate.Terminology English: Inferior colliculusLatin: Colliculus inferior Function Involved in sound location...
