It begins when stimulus changes the membrane potential of a receptor cell. A receptor cell converts the energy in a stimulus into an electrical signal. Receptors are broadly split into two main categories: exteroceptors, which rec…

WebPrincipal steps of sensory processing. In physiology, transduction is the change of a stimulus from one form to another. Transduction in the nervous system means synaptic events where an electrical signal is converted into a chemical one by the release of neurotransmitters. In sensory transduction a chemical or physical stimulus is transduced ... WebSensory receptors are specialized neurons that respond to specific types of stimuli. When sensory information is detected by a sensory receptor, sensation has occurred. For example, light that enters the eye causes chemical changes in cells that line the back of the eye.
