Document Summary

Advanced topics in human cognition - class 2. Multi-unit recording and single cell recording are very invasive for humans we typically stay to the options that are less invasive. Electrode(s) placed in or near a neuron (invasive) Measure # of action potentials per second. Very small electrode implanted into axon (intracellular) or outside axon membrane (extracellular) records neural activity - does not stimulate it. See what the cell does when the animal is presented with speci c stimuli: 2. event-related potentials (erp) Measures summed electrical potentials from millions of neurons (sensitive to dendritic currents) Single-cell recordings: very small electrode implanted into axon (intracellular) or outside axon membrane (extracellular) records neural activity (does not stimulate it) Hallie berry cells: evidence of hierarchical organization in vision, but what suits at the top of the hierarchy, a grandmother cell hypothetically responds to only one stimulus. Three kinds of neural codes: rolls and deco (2002) summarize 3.
