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.
This pattern coincides with two internal processes referred to as the a-process and b-process. Hence, the opponent-process theory predicts that subjects will show no reaction following a stimulus after a repetition of this same stimulus. It is the after-reaction that is much larger and prolonged than if an initial reaction to a stimulus ...
This series of actions by CaMK desensitizes olfactory receptors to prolonged odorant exposure. [3] When the nose is covered taste is a lot harder because the air we breathe goes into the mouth as well. A common idea is that vanilla smells sweet and that is because we taste sweet when we eat vanilla flavorings. [6]
In physiology, a stimulus [1] is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [ 2 ]
Listener fatigue (also known as listening fatigue or ear fatigue) is a phenomenon that occurs after prolonged exposure to an auditory stimulus. Symptoms include tiredness, discomfort, pain, and loss of sensitivity. Listener fatigue is not a clinically recognized state, but is a term used by many professionals.
The multimodal neurons lead to change of behavior and assist in analyzing behavior responses to certain stimulus. [1] Information from two or more senses is encountered. Multimodal perception is not limited to one area of the brain: many brain regions are activated when sensory information is perceived from the environment. [2]
Exposure to light at night, particularly blue light that can be emitted from phones and other screens, can make it harder to get to sleep, Jaime Zuckerman, a clinical psychologist specializing in ...
Upregulation of receptors, on the other hand, can result in super-sensitized cells, especially after repeated exposure to an antagonistic drug or prolonged absence of the ligand. Some receptor agonists may cause downregulation of their respective receptors, while most receptor antagonists temporarily upregulate their respective receptors.
