Document Summary

Gil talks w/ mary at the park then a few days later, passes the park & remembers what she was wearing (behavioural). Complex pathway for conducting signals without no interruptions. Forms groups of interconnected neurons -> neural circuits. Cell body: metabolic center: contains mechanisms to keep cell alive. Dendrites: branch out from cell body to receive signals from other neurons. Axons: long processes that transmit signals to other neurons: also called nerve fibers. Microstimulation - v4 recording [visual], fef microstimulation (slide: can combine with single cell recording. E. g. image created by light reflected by mary that gets into gil"s eye, not mary"s eye- representations of mary (p. 33) First to explain why our cortex is crumpled up. Cortical tissue is thin layer of bodies outside of brain - explains it has to be crumpled up: results to bumps on brain - gyri & sulci.
