As the electrical activity monitored by EEG originates in neurons in the underlying brain tissue, the recordings made by the electrodes on the surface of the scalp vary in accordance with their orientation and distance to the source of the activity.

Electrical-engineering document from University of Colorado, Denver, 4 pages, Corpus Callosum connects the left and right halves of the brain - The Nervous System Master controller/communicator of the body Electrical and Chemical Signals Fast Acting Functional Cell: Neuron Supporting Cell: Glial Afferent (Sensory signal) → signal g

Nervous System A complex network of nerves and cells that transmit signals between different parts of the body, responsible for controlling and coordinating bodily functions.Neuron: A nerve cell that carries electrical signals in the nervous system.Neurotransmitter: Chemical substances that transmit signals across a synapse from one neuron to another or to a target cell (e.g., […]

Overall, whereas a wealth of experimental data had accumulate over the years – starting from Luigi Galvani (1737–1798 and Alessandro Volta (1745–1827) to Carlo Matteucci (1811–1868) and Emil du Bois-Raymond (1818–1896) – demonstrating the role of electricity in the peripheral nervous system, the intrinsic electrical functioning of ...

And in a directional pathway, those nerve cells that are responding to the outside world are taking that information in and turning it into an electrical signal that passes from one nerve cell to another, gets highly processed. 0:06:37.3 JL: And ultimately, the nervous system is designed to respond to sensory signals.
