PS262 Chapter Notes - Chapter 4: Fusiform Face Area, Parahippocampal Gyrus, Extrastriate Body Area
Document Summary
Research on the physiology of vision has been dominated by 2 major themes: Describing the types of stimuli that cause neurons at different levels of the visual system to respond. Describing how neurons in the visual system are organized. Spatial organization: the way stimuli at specific locations in the environment are represented by activity at specific locations of the nervous system. Cortical magnification: apportioning to the small fovea of a large area on the cortex (determined by brain imaging: brain imaging: Number of techniques that result in images that show which areas of the brain are active. Module: a structure that is specialized to process info about a particular type of stimulus. Fusiform face area (ffa): located in the fusiform gyrus on the underside of the brain below the it cortex. Propognosia: difficulty recognizing faces of familiar people. Parahippocampal place area (ppa): activated by pictures depicting indoor and outdoor scenes.
