PS101 Lecture Notes - Lecture 5: Axon Terminal, Myelin, Darpa
Document Summary
A robot, imitator of simple human behaviour made by darpa, 10+ years, billions of dollars. Company where craziest experiments and research is done. Brain processing capacity is = 2k tianhe-2 (the world"s fastest supercomputer) or 3000x a good imac. Specialized cells that carry messages throughout the nervous system. Pyramidal cells responsible for intricate brain matters (thoughts, thinking) Afferent neurons (sensory) relay info from the senses to the brain and spinal chord. Efferent neurons (motor) send info from the central nervous system to the glands and muscles, enabling the body to move. Interneurons everything inbetween, carry info between neurons in the central nervous. Like the glue that holds neurons together, prevent signals from intercrossing. Can in some cases act like a neuron bc of processing abilities. Support rolls for neurons that do the heavy lifting . Happens locally rather than interacting with the brain, allows for quick movement.
