Document Summary
Electricity flow of electrons from a body that contains a higher charge (more electrons) to a body that contains a lower charge (fewer electrons) Negative pole source of electrons; higher charge. Positive pole location to which electrons flow; lower charge. Electrical potential electrical charge measured in volts; the ability to work through the use of stored potential electrical energy. Volt measure of a differences in electrical potential. Electrical stimulation - passage of an electrical current from the uninsulated tip of an electrode through tissue, resulting in changes in the electrical activity of the tissue. Neurons can convey information as a wave induced by stimulation on the cell body travelling down the axon to its terminal. Voltmeter - device that measures the flow and the strength of electrical voltage by recording the difference in electrical potential between two bodies. Electroencephalogram (eeg) - graph that records electrical activity through the skull or from the brain and represents graded potentials of many neurons.
