In physiology, transduction is the translation of arriving stimulus into an action potential by a sensory receptor. It begins when stimulus changes the membrane potential of a sensory receptor . A sensory receptor converts the energy in a stimulus into an electrical signal. [ 1 ]
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception.
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal root ganglia of the spinal cord ...
During sensation, sense organs [3] collect various stimuli (such as a sound or smell) for transduction, meaning transformation into a form that can be understood by the brain. Sensation and perception are fundamental to nearly every aspect of an organism's cognition, behavior and thought.
Hyperpolarization of the hair cell, which occurs when potassium leaves the cell, is also important, as it stops the influx of calcium and therefore stops the fusion of vesicles at the ribbon synapses. Thus, as elsewhere in the body, the transduction is dependent on the concentration and distribution of ions. [7]
The transduction of light into neural activity occurs via the photoreceptor cells in the retina. When there is no light, Vitamin A in the body attaches itself to another molecule and becomes a protein. The entire structure consisting of the two molecules becomes a photopigment. When a particle of light hits the photoreceptors of the eye, the ...
Transduction in general is the transportation or transformation of something from one form, place, or concept to another. In psychology, transduction refers to reasoning from specific cases to general cases, typically employed by children during their development. The word has many specialized definitions in varying fields.
The communication within and among these specialized areas of the brain is known as functional integration. [ 3 ] [ 4 ] [ 5 ] Newer research has shown that these different regions of the brain may not be solely responsible for only one sensory modality , but could use multiple inputs to perceive what the body senses about its environment.
