CO SCI 136 Lecture Notes - Lecture 10: Frontal Lobe, Temporoparietal Junction, Memory Consolidation
Document Summary
The brain: cerebral cortex: outer layer of the brain, convoluted(scrunched up): gyri ridges, sulci grooves, two hemispheres joined by the corpus callosum. Frontal lobe: planning, inhibition (preventing inappropriate social responses) , decision making. Parietal lobe: somatosensory functioning (skin, body, touch, pain, warmth) Contralateral control: each hemisphere controls the opposite effect- vision, attention, action. What is cognitive neuropsychology: the study of cognitive impairments following brain injury, looks at individual cases to determine what processes have been disturbed, develop an understanding of normal cognitive processing. Associations: the abilities or tasks that patients can"t do (e. g agnosia inability to recognize objects, prosopagnosia is the inability to recognize faces) Looks for dissociations and double dissociations in different abilities: dissociation: a patient who is impaired at one task but normal at another, double dissociation: 2+ patients with opposing deficits. Multiple models to interact to result in a particular function of behavior, e. g. iformation input >
