The Visual Cortex: Anatomy

The Visual Cortex: Anatomy. The LGN projects to ipsilateral primary visual cortex (area 17, striate cortex). Remember that this means that left visual field goes to right area 17. Also remember that left visual field gets input from left eye (nasal retina) and right eye (temporal retina).

Magnification Factor

Figure 4.4 Points A, B, and C on the cup create images at A, B, and C on the retina and cause activation at points A, B, and C on the lateral geniculate nucleus (LGN). The correspondence between points on the LGN and retina indicates that there is a retinotopic map on the LGN.
