Document Summary

Neurons - cells in the nervous system that communicate with one another to perform information-processing tasks. Basic building blocks of nervous system linked together in circuits. Thomas hobbes: the mind is what the brain does (monism) Subjective experience is how it feels to be a brain". 3 main parts of neuron: cell body, dendrites, axon. Cell body(soma): coordinate information processing tasks; biochemical structures keep the cell alive; largest component. Dendrites: receive info from other neurons and relay it to the cell body which combines and processes it. Axons: transmit info to other neurons, muscles, or glands. Single axon (can be up to 1m long!) Myelin sheath: insulating layer of fatty material. Glial cells: are support cells found in the nervous system. Synapse: space between the axon of one neuron and the dendrites or cell body of another neuron. Single neuron can have thousands of synapses. 100 - 500 trillion synapses in an adult brain.
