PSYC1020 Lecture Notes - Lecture 12: Laterality, Lateralization Of Brain Function, Peripheral Vision
Document Summary
Lecture 12 brain laterality and judgement/decision making. Lateralised functions: some cognitive functions rely more on one side of the brain than the other. Right hemisphere: tone of voice, faces, perceptual grouping. Crossed (contralateral) functions: movement, sensation and vision, left hemisphere, right body movement and sensation, right side vision, right hemisphere. Language is lateralised to the left hemisphere in most people: language comprehension, speech, reading, speech production. Language and hand dominance: no overall dominant hemisphere, right handed people, 95% have language in left hemisphere, left handed people, 70% have language in left hemisphere. Determining language lateralisation fmri brain activity during language: still being researched, often see activation in both hemispheres so hard to determine lateralisation. Primary motor and sensory cortex: connect to contralateral side of body, right to left, left to right. Contralateral vision: each side of visual space mapped to contralateral visual cortex.
