Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.
Stimulus filtering occurs when an animal's nervous system fails to respond to stimuli that would otherwise cause a reaction to occur. [1] The nervous system has developed the capability to perceive and distinguish between minute differences in stimuli, which allows the animal to only react to significant impetus. [ 2 ]
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 .
The basis for signal transduction is the transformation of a certain stimulus into a biochemical signal. The nature of such stimuli can vary widely, ranging from extracellular cues, such as the presence of EGF, to intracellular events, such as the DNA damage resulting from replicative telomere attrition.

In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes.
The dual perception of the stimulus produces an interaction that facilitates association of the experience through an additive neural response and memorization of the stimulus. This association can also be made between olfactory and tactile stimuli during the act of swallowing. In each case, temporal synchrony is important. [28]
Dendritic compartmentalization has implications in information processing, where it serves as a foundation of trans-neuron signaling, processing stimuli, computation, neuronal expressivity, and mitigating neuronal noise. Likewise, this phenomenon also underlies the storage of information by optimizing learning capacity and storage capacity.
The orienting response is a reaction to novel or significant stimuli. In the 1950s the orienting response was studied systematically by the Russian scientist Evgeny Sokolov , who documented the phenomenon called " habituation ", referring to a gradual "familiarity effect" and reduction of the orienting response with repeated stimulus presentations.
