PS262 Chapter Notes - Chapter 4: Functional Magnetic Resonance Imaging, Magnetic Resonance Imaging, Visual Cortex
Document Summary
Illustrates cortical magnification: stimulation of the small area near the fovea activated a greater area on the cortex (red) than stimulation of the larger area in the periphery (blue) One location column: many orientation columns: 1-mm dimension for location columns. Ps262 chapter 4 cortical organization: one location column is large enough to contain orientation columns that cover all possible orientations (hyper column) How do orientation-sensitive neurons respond to a scene: focus on the tree trunk specifically on the part of the trunk that is shown passing through a, b, c. Rectangular solid: was presented with a 2-choice task which included the target object and another stimulus (ex. Ps262 chapter 4 cortical organization: basic principle of neuropsychology: we can understand the effects of brain damage by determining double dissociations. The behaviour of patient d. f: milner and goodale:used double dissociations to study d. f, d. f.
