Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin. Subsequently, however, the sensation of the ...
Habituation. Habituation is a form of non-associative learning in which a non-reinforced response to a stimulus decreases after repeated or prolonged presentations of that stimulus. [1] For example, organisms may habituate to repeated sudden loud noises when they learn these have no consequences.
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 ...
Olfactory fatigue. Olfactory fatigue, also known as odor fatigue, olfactory adaptation, and noseblindness, is the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound. [ 1] For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but ...
A heavily studied example of a fixed action pattern is the feeding behavior of the Helisoma trivolvis , a type of snail. A study has shown that the intricate connections within the buccal ganglia (see nervous system of gastropods) form a central system whereby sensory information stimulates feeding in the Helisoma.
Multisensory integration, also known as multimodal integration, is the study of how information from the different sensory modalities (such as sight, sound, touch, smell, self-motion, and taste) may be integrated by the nervous system. [1] A coherent representation of objects combining modalities enables animals to have meaningful perceptual ...
Habituation involves decreased levels of attention and responsiveness to a stimulus that is no longer perceived as being novel. [7] In the realm of olfactory memory, habituation refers to a decrease in responsiveness to an odor as a result of prolonged exposure (restricted to a certain repeated stimulus), which involves adaptation of cells in ...
Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response. [1] Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated. For example, repetition of a painful stimulus may ...
