PS101 Lecture Notes - Lecture 3: Transcranial Magnetic Stimulation, Positron Emission Tomography, Morris Water Navigation Task
Document Summary
Topics: techniques to study the brain, the nervous system, organization of the brain, neural communication, brain lateralization, brain plasticity. Weighs 3 pounds 2% of body fat and 20% of our oxygen. Wrinkly greyish-beige colour, feel like soft tofu. Study what happened when part of the brain isn"t working. Case studies of brain damage, lesioning,electrical simulation. Use equipment to study normal brain activity. Two approaches to learning about the brain: magnetically deactivating. Case studies of brain damage, lesioning, electrical stimulation, Use fancy equipment to study normal brain structure and function. Ct scans, mri, fmri, pet scans, eeg, erp, dti. Surgically destruction of brain tissue to see the effect (done on animals) Eg: morris water maze rats without lesion went right to platform, rats without hippocampus had to look around for it again. Can result in behaviours such as giggling, head turning, or simulated vivid. Procedure to temporary inactivate the region of brain images.
