Understanding EEG Part 2: Formation of a Dipole

Overview

The generation of the EEG signal is often a difficult concept to understand. These 2-3 minute animations were student generated. Animation 1 explains action potentials and postsynaptic potentials. Animation 2 explores the formation of dipoles in the brain, and Animation 3 investigates how signal is propagated to the scalp where it is recorded by electrodes.
