Document Summary
Structural neuroimaging techniques - advanced technology to create images of the living, healthy brain. Computerized axial tomography (ct or cat scans) Functional brain imaging techniques - allow us to watch the brain in action. Neurons - cells in the nervous system that communicate with one another to perform information processing tasks. Around 86 million neurons in the brain. Glia - cells that help to support neurons. Astroglia - creates the blood-brain barrier and regulate flow of blood into different brain regions. Oligodendroglia - provide myelin in the brain and spinal cord to speed up transmission of neurons. Microglia - clean up dead cells and defend against infection in the brain. Dendrites - receive information from other neurons and sensory receptors. Cell body - receives info from dendrites and if enough stimulation is received the message is passed to the axon. Axon - carries the neuron"s message to the terminal buttons.
