Each ganglion cell has a characteristic receptive field that consists of a group of photoreceptors that view light from a small portion of the whole visual field. When stimulated with light, these photoreceptors activate the ganglion cell, relaying action potentials to the thalamus of the visual cortex. This ensures that the many pieces of information received by photoreceptors are delivered to the brain as a single signal.
