Document Summary

Neuroscience: the study of the brain and the nervous system. Neuroimaging: techniques that allow for study brain activity and structure by obtaining visual images in awake humans. Dendrites: the parts of neurons that receive input from other neurons. Axon: the part of the neuron that carries information away from the cell body toward other neurons. Axon terminal: the end of a neuron"s axon, from which neurotransmitters are released. Glia: the cells that, in addition to neurons, make up the nervous system. Resting potential: the electrical charge of a neuron when it is at rest. Concentration gradient: the difference in concentration of sodium ions inside and outside of the neuron. Ion channels: pores in the cell membrane that can open and close to allow certain ions into and out of the cell. Sodium-potassium pump: protein molecules in the membrane of cells that push out sodium ions and push in potassium ions.
