Chemical stimuli, such as odorants, are received by cellular receptors that are often coupled to ion channels responsible for chemotransduction. Such is the case in olfactory cells . [ 12 ] Depolarization in these cells result from opening of non-selective cation channels upon binding of the odorant to the specific receptor.
Stimulation, in general, refers to how organisms perceive incoming stimuli. As such it is part of the stimulus-response mechanism. Simple organisms broadly react in three ways to stimulation: too little stimulation causes them to stagnate, too much to die from stress or inability to adapt, and a medium amount causes them to adapt and grow as they overcome it.
In mammals, taste stimuli are encountered by axonless receptor cells located in taste buds on the tongue and pharynx. Receptor cells disseminate onto different neurons and convey the message of a particular taste in a single medullar nucleus. This pheromone detection system deals with taste stimuli.
Animals exhibiting, or responding to, characteristics that represent a supernormal stimulus usually display them as a result of selective pressures.Co-evolution between animals displaying supernormal stimuli, and the organisms responding to the supernormal stimuli, rely on evolution and propagation of genetics, behavioral patterns, and other biological factors.

A biochemical cascade, also known as a signaling cascade or signaling pathway, is a series of chemical reactions that occur within a biological cell when initiated by a stimulus.
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used. [1]
A research review in The Journal of Sex & Marital Therapy found that as we get “used to” certain sexual stimuli, we don’t get aroused in the same way—but new experiences can increase ...
The sign stimulus, also known as key stimulus or releaser, is the determining feature of a stimulus that produces a response.Sign stimuli are often found when observing a fixed action pattern (FAP) that is an innate behaviour with very little variance in the manner in which the actions are executed.
