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.
When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system . External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response .
Visual adaptation is the temporary change in sensitivity or perception when exposed to a new or intense stimulus, and the lingering afterimage that may result when the stimulus is removed. These continuous small adjustments reflect the neural coding process of the visual system , and exist so the brain can attempt to "normalize" the visual ...
Habituation is a form of non-associative learning in which an organism’s 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 that these have no consequences. [2]
For example, where our visual system may fool us in one case, our auditory system can bring us back to a ground reality. This prevents sensory misrepresentations, because through the combination of multiple sensory modalities, the model that we create is much more robust and gives a better assessment of the situation.
Multimodal perception is the ability of the mammalian nervous system to combine all of the different inputs of the sensory nervous system to result in an enhanced detection or identification of a particular stimulus. Combinations of all sensory modalities are done in cases where a single sensory modality results in an ambiguous and incomplete ...
The genital sensory cortex, or what Wise refers to as the “brain crotch,” is a recognized area of the primary sensory cortex that registers sexual stimulation.
The adequate stimulus is the amount and type of energy required to stimulate a specific sensory organ. [1] Many of the sensory stimuli are categorized by the mechanics by which they are able to function and their purpose. Sensory receptors that are present within the body typically are made to respond to a single stimulus.
