Webreceptive field, region in the sensory periphery within which stimuli can influence the electrical activity of sensory cells. The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections. … Receptive fields have been identified for neurons of the auditory system, the somatosensory system, and the visual system. The term receptive field was first used by Sherrington in 1906 to describe the area of skin from which a scratch reflex could be elicited in a dog. Ver mais The receptive field, or sensory space, is a delimited medium where some physiological stimuli can evoke a sensory neuronal response in specific organisms. Complexity of the receptive field ranges from the … Ver mais In the somatosensory system, receptive fields are regions of the skin or of internal organs.
