Sensory adaptation is also known as neural adaptation. A process in which changes in the sensitivity of sensory receptors arise in relation to the stimulus called Sensory adaptation. All senses are supposed to involve in the sensory adaptation. We get used to things. This goes for lots of things in life including smells, sights, sounds, people, games, and conditions. Looks like after a while we get used to everything. Sensory systems continually adapt their responses to match the existing environment. These modifications occur at various levels of the system and gradually appear to adjust even for highly abstract perceptual representations of the stimulus.

This process of dark adaptation is established through three changes in the visual system.
(a) The pupil expands instantly after sensing the reduction of the light stimuli .The expansion of the pupil is essential so that additional available light can go in and stimulate the retina.
(b) The color receptors or cones become gradually sensitive. The cones attain dark adaptation in a complete way, within five to ten minutes of low levels of brightness.
(c) Finally the night vision receptors or rods become gradually sensitive.
Light Adaptation
Light adaptation takes less time as compared to dark adaptation. Generally the changes are contrary of that in dark adaptation. The pupil becomes smaller instantly in light adaptation to permit less light to enter the eye. The cones and the rods become less sensitive to light. Light adaptation takes only a few seconds, happening faster than dark adaptation due to the nature of the photons to enter the eye quickly in increased light intensity and abolish the extra light sensitive …show more content…
However, very hot or very cold stimuli may destroy touch receptors, and this penetrating stimulation may be interpreted as pain sensation.
Taste and Smell
Low concentrations of several chemicals present in the air can be sensed by the sensory receptors in the nose. These chemicals that we rapidly detect include those in perfumes or air fresheners.
Conclusion
Studies of adaptation continue to expose astonishing and complex forms of flexibility in sensory systems, from peripheral receptors to central mechanisms coding highly intellectual properties of the stimulus. The finding that vision adapts in such similar ways to such a diverse array of perceptual characteristics recommends that adaptation is an inherent feature of visual coding that is obvious throughout the visual stream. We must consider the statistics of the natural world, flexibility at multiple levels of sensory processing, and the consequences for encoding of sensory information at each stage.
