PSYC 309 Lecture Notes - Lecture 8: Posterior Parietal Cortex, Phantom Limb, Sportfreunde Stiller
Document Summary
Your brain is to blame blakeslee: e. g. feels shadowy figure standing behind; feels herself leaving her body and floating in space. Illusory own body perceptions: case reports and relevance for bodily self-consciousness. Predominately lower trunk and legs; lesser degree upper trunk and neck. Importance of right posterior and medial parietal cortex for illusory own body perceptions. Both: sensory deprivation brain areas if it doesn"t have normal input, system wired up a certain way > damage (stroke, seizures) or alteration in neurotransmitter system (no tissue damage), same way both impaired circuitry. Supernumerary phantom limbs: no amputation; 2 normal functioning limbs, odd sensation of having third limb, feel additional limb; coming out of elbow, not shoulder, for a lot of these conditions, disturbance in how representation are being integrated. An fmri case study of supernumery phantom limb. Under normal circumstances, information from a number of sources is combined to compute unitary percept of the body.
