Document Summary

Optic chiasm - all axons, and no cell body. Simple cells in primary visual cortex, responds to line orientations. Only responds to orientation in a specific space in visual field (also responds to color) In primary visual cortex, you have columns of cells that respond to different orientations at different spots in visual field. Within a column cells have different orientation selectivity and respond to different color combos. Respond to movement, and the faster something moves, the more it responds **important** Hypercomplex fields include inhibition in one portion of field. Line is moving around in a visual field, will respond until a line moves into a negative off area hierarchical organization. Primary visual cortex (striate cortex, v1) has simple, complex, and hypercomplex receptive fields. Complex and hypercomplex receptive fields have also been found in secondary (v2) and higher order visual cortex. Dorsal pathwaay - connects w/parietal lobe, so connects with motor cortex.
