Sensory Transduction

Sensory transduction is a fundamental neurobiological process that converts (transduces) electrochemical impulses to signals that can travel neuron-to-neuron — from sensory receptors in the peripheral nervous system (PNS) to the central nervous system (CNS)/brain to become a conscious perception of that stimulus. This process allows organisms to detect and respond to changes in their environment. In humans, sensory receptors are converted to electrical signals (action potentials) which are transduced into chemical signals (neurotransmitters) to cross the synaptic cleft that separates neurons, to be received by the next neuron and reconverted to action potentials to resume the journey.
