EEG sensor

An EEG sensor is a circular object in the model window used to acquire signal data to be visualized in the EEG monitor window. The amplitude of the signal is calculated from the voltage potential of all neurons within an adjustable circular surface. Neurons in the center of the circle have a greater influence than neurons at the edge.
 * Use the Add EEG signal command to create a new EEG sensor
 * Several EEG sensors can exist simultaneously
 * EEG sensors can be moved with the left mouse button
 * To change the size of a EEG sensor, use the mouse wheel
