    Visual Field and the Human Visual System The visual field represented in its projection to the retina demonstrates how the lens of the eye inverts the image being viewed. Up is inverted down and right is represented on the left. Signals from the right retinas (left visual field) of both eyes travel through the optic nerve, optic tract, and optic radiations to the primary visual cortex in the right hemisphere. Signals from the left retinas (right visual field) travel to the left hemisphere. Primary visual cortex lies in the colored area along the calcarine sulcus. Colors show how the different sectors of the visual fields map on to primary visual cortex.

    Mapping Human Striate Cortex (V1) with Positron Emission Tomography (PET) •Checkerboards were used to present stimuli to different parts of the visual fields. The leftmost checkerboard is a foveal stimulus, the middle one presents a stimulus close to the fovea ( parafoveal ), and the rightmost one is a peripheral stimulus that surrounds the parafovea from 5.5 to 15°. •Stimuli could also be presented to the upper quadrant (e.g., rightmost stimulus) or the lower quadrant (e.g., middle stimulus).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
