{{short description|Method by which information is represented in the brain}}
'''Neural coding''' (or '''neural representation''') refers to the relationship between a [[Stimulus (physiology)|stimulus]] and its respective neuronal responses, and the [[Electrophysiology|signalling relationships]] among networks of neurons in an [[Neuronal ensemble|ensemble]].<ref name="Brown">{{cite journal |vauthors=Brown EN, Kass RE, Mitra PP |title=Multiple neural spike train data analysis: state-of-the-art and future challenges |journal=Nat.

The [[Channel capacity|simplicity]] of action potentials as a methodology of encoding information factored with the indiscriminate process of [[Summation (neurophysiology)|summation]] is seen as discontiguous with the specification capacity that neurons [[Neurotransmission#Cotransmission|demonstrate at the presynaptic terminal]], as well as the broad ability for complex neuronal processing and regional specialisation for which the [[Large-scale brain network|brain-wide integration]] of such is seen as fundamental to complex
As such, theoretical frameworks that describe encoding mechanisms of action potential sequences in relationship to observed patterns are seen as fundamental to neuroscientific understanding.<ref name="thorpe">{{cite book |first=S.J. |last=Thorpe |chapter=Spike arrival times: A highly efficient coding scheme for neural networks |chapter-url=https://www.researchgate.net/publication/247621744 |format=PDF |pages=91–94 |editor1-first=R. |editor1-last=Eckmiller |editor2-first=G. |editor2-last=Hartmann |editor3-first=G. |editor3-last=Hauske | editor3-link = Gert Hauske |title=Parallel processing in neural systems and computers |url=https://books.google.com/books?id=b9gmAAAAMAAJ |year=1990 |publisher=North-Holland |isbn=978-0-444-88390-2}}</ref>
