PSYB65H3 Chapter Notes - Chapter 6: Postcentral Gyrus, Visual Cortex, Retinal Ganglion Cell
Document Summary
Sensation: the detection of some aspect of a stimulus in the environment. Perception: the way in which we (or our brains) interpret the information that is gathered by the senses. The primary sensory cortex: the first part of the cortex that receives information relayed from the senses through the thalamus. It was the most direct access to the information provided by the sensory systems (eyes). The primary sensory cortex sends this information to secondary cortical areas. The secondary sensory cortex: highly interconnected, and thus the secondary sensory cortex also receives information from other areas of the secondary sensory cortex. It sends its information to the association cortex. The association cortex: receives information from more than one sense. Senosry systems are characterized by hierarchal organization. Each level of the organization contains functionally distinct cortical areas. The processing of sensory information occurs in parallel throughout the cortex. Eye: large number of very specialized receptors that have one function (light signals)
