Document Summary

Describe some of the techniques used to study brain activity. Electrical stimulation: passing an electrical current from the tip of an electrode through brain tissue, resulting in changes in the electrical activity of the tissue. Electricity: a flow of electrons from a body that contains a higher charge. Volt: a measure of a difference in electrical potential. Voltmeter: a device that measures the difference in electrical potential. Negative pole: the source of electrons; higher charge. Positive pole: location to which electrons flow; lower charge. Electrical potential: an electrical charge measured in volts; the ability to do (more electrons) to a body that contains a lower charge (fewer electrons) work through the use of stored potential electrical energy between two bodies. Electroencephalogram: electrical brain graph that records electrical activity through the skull to form the brain and represents graded potentials of many neurons **waves that travel along an axon**
