PSYC30018 Lecture Notes - Spring 2018 Lecture 2 - Electroconvulsive therapy, Gold rush, Deep brain stimulation
Document Summary
Won 1963 nobel prize for understanding the basis of the action potential: extracellular recordings of action potentials. Recorded from single neurons in the visual cortex of anesthetised cats. Won 1981 nobel prize for showing how single neurons encode specific visual features. Electrical recordings in local regions of brain tissue: extracellular recordings of single neurons, anesthetised animals. Contributed to much of our understanding of sensory and motor areas: awake behaving studies. Good models of higher cognitive function in humans. Memory, recognition, attention: multiple neurons can be studied with electrode arrays. Using the same electrode as single unit recording. Low pass filter slow variations in voltage. Activity of neurones up to 3mm from the electrode. Summed activity of large numbers of neurons with synchronous input. More likely to reflect type cells with dendrites facing in the same direction away from cell body eg. pyramidal cells.
