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.
These MET channels are cation-selective transduction channels that allow potassium and calcium ions to enter the hair cell from the endolymph that bathes its apical end. The influx of cations, particularly potassium, through the open MET channels causes the membrane potential of the hair cell to depolarize.
It serves as part of a negative feedback loop in signal transduction. It is only sensitive to the neurotransmitters or hormones released by the neuron on which the autoreceptor sits. Similarly, a heteroreceptor is sensitive to neurotransmitters and hormones that are not released by the cell on which it sits. A given receptor can act as either ...
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
Mechanosensation is the transduction of mechanical stimuli into neural signals. Mechanosensation provides the basis for the senses of light touch, hearing, proprioception , and pain. Mechanoreceptors found in the skin, called cutaneous mechanoreceptors, are responsible for the sense of touch.
Deflections of the stereocilia in the opposite direction toward the shortest stereocilia causes transduction channels to close. In this situation, the hair cells become hyperpolarized and the nerve afferents are not excited. [7] [8] [9] There are two different types of fluid that surround the hair cells of the inner ear.
The glomerulus process in dogs is divided in 3 parts: signal acquisition, signal transduction, and signal processing. Some dogs have as many as 100 times more ORNs than humans do, producing a correspondingly sharpened ability to detect and discriminate among millions of odors. [ 11 ]
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
