PSY270H5 Lecture Notes - Lecture 2: Cerebrum, Parietal Lobe, Functional Magnetic Resonance Imaging
Document Summary
Describe structure and function of a neuron. Review major anatomical divisions of the brain. Key themes of anatomy: structure vs. function, localization vs. They neurotransmitters bind to the post synapse. action. synapse classified into 3 categories: inhibitory neurotransmitter- on single; glutamate- All cells have some action if they receive signals or not. There are action potentials happening even when at rest. action potential. A very strong signal is indicated by a lot of. Post-mortem investigation: oldest and only way at one point in time. Ct: an x-ray of different angles that gives us an image of the brain. Mri: much clearer (high spatial resolution) picture than a ct. Single-cell recording/stimulation/lesions/tms- exclusively on humans, allows temp lesion. Handheld device of magnetic devise and it lesions a certain part of the brain: record activity from an individual brain cell. Eeg- measures the electrical potential of the brain as a whole.
