Detailed explanation-1: -Nociception is the neural processes of encoding and processing noxious stimuli. Nociception refers to a signal arriving at the central nervous system as a result of the stimulation of specialised sensory receptors in the peripheral nervous system called nociceptors.
Detailed explanation-2: -Transduction: the conversion of one form of energy into another. In sensation, this is the transformation of sights, sounds, and smells into neural impulses our brain can interpret.
Detailed explanation-3: -The perceptual process begins when our sensory receptors (eyes, ears, tongue, nose, and skin) come in contact with sensory stimuli (sights, sounds, tastes, odours, and textiles) around us.
Detailed explanation-4: -General Definition of Sensory Coding Reception, whereby specialized sensory receptors absorb physical energy from sensory stimuli. Transduction, which involves the conversion of this physical energy into electrical energy in the form of neuronal firing.
