Document Summary

Try to decompose at least three processes necessary to engage in that activity. Example: reading: eyes receive visual stimulus, brain recognize them as letters, brian parsing letters into words, brain interprets meaning from text . The brain is responsible for many processes (sensation, perception, learning, attention, memory, language) Almost everything we do, the brain is involved with, even if that is not immediately obvious (regulating breathing and consciousness) Not limited to involvement in difficult thinking. Glial cells: building blocks of the brain (communication, support cells, clean up waste, provide nutrients, myelinate axons. Input zone dendrites (receive signals from other neurons, comes from a greek word that means tree) Cell body (soma, which contains the nucleus of the cell) Axon starts the output zone of the neuron: neurons only have one axon, but have many dendrites, axon control action potential (take things out and away from the cell. Myelin fatty tissue (covers the axon, increases speed of the axon)
