Document Summary

1. 3 methods for studying: lesion method: study effects of tissue damage to the nervous system, lesion: tissue damage. Clinical lesions: people fall down; damage their brains, experimental lesions: Part of the brain can be destroyed. Recording methods: electrical recording, eeg (electroencephalograph): records fluctuations in electrical activity, useful for sleep and epilepsy research. Electrical activity is recorded from the surface of the skull: brain waves represent electrical changes over time, evoked potential (or erp), an eeg response evoked by a stimulus. Usually done clinically: single neuron recording, records action potentials from individual neurons. Very small; activity of place cells can be recorded in a brain area known as the hippocampus: chemical recording, micro-dialysis. Probe can be put into the brain to sample the chemical activity in the brain; measurement: sampling of cerebrospinal fluid. Imaging methods: ct or cat (computerized tomography, studies the brain structure, modified x-ray to take a picture of the brain, common machines, smri (structural magnetic resonance imaging)
