El sistema sensorial es parte del sistema nervioso, responsable de procesar la información sensorial. El sistema sensorial está formado por receptores sensoriales y partes del cerebro involucradas en la recepción sensorial. Los principales sistemas sensoriales son: la vista, el oído, el tacto, el gusto y el olfato. El campo receptivo es la parte específica del mundo a la que un órgano y unas determinadas células del receptor responden. Por ejemplo, el campo receptivo de un ojo es la parte del mundo que éste puede ver.

The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, auditory (hearing), somatic sensation (touch), gustatory (taste), olfaction (smell) and vestibular (balance/movement). In short, senses are transducers from the physical world to the realm of the mind where we interpret the information, creating our perception of the world around us. The receptive field is the specific part of the world to which a receptor organ and receptor cells respond. For instance, the part of the world an eye can see, is its receptive field; the light that each rod or cone can see, is its receptive field. Receptive fields have been identified for the visual system, auditory system and somatosensory system, so far.
