Event related potentials are electrical properties of biological cells and tissues reacting to an internal or external stimulus. Electrodes are attached to the scalp and the electrical activity is the amplified and deteced on a computer screen. The activity of neurons closest to the electrodes are being recorded in order to record the effect of the ERP (could be a tone or light flash). strong responses in the Visual cortex may indicate of a person with healthy a visual system. ERP techniques have been found useful in finding information on attention.
