PSYC 309 Lecture Notes - Lecture 8: Angular Gyrus, Posterior Parietal Cortex, Temporoparietal Junction
Document Summary
Out of body experiences: ex feel a shadowy figure behind you, no one"s there; feel yourself leaving your body looking at body. Info from sense processed in primary sensory brain regions combined in some areas in the brain; ex recognize pic of a dog faster if its bark is with it. Joint, tendon, bone sensors: where body is positioned in space. If multisensory" regions (that combine info of many senses) stimulated by current can change sense of body. Woman with electrode in left angular gyrus: when it was stimulated she turned her head right to see. Shadow" figure under/behind her that copied her body position :. Unusual perception of her own body but unable to realize she"s sensing her own body. Feeling of shadowy presence can occur: electrical stimulation, sensory deprivation (mountain climbers, lone sailors), people who"ve had strokes/disruptions to brain blood flow.
