== Hypothesized coding schemes ==

A sequence, or 'train', of spikes may contain information based on different coding schemes. In some neurons the strength with which ana postsynaptic partner responds may depend solely on the 'firing rate', the average number of spikes per unit time (a 'rate code'). At the other end, a complex '[[temporal code]]' is based on the precise timing of single spikes. They may be locked to an external stimulus such as in the visual<ref>Burcas G.T & Albright T.D. Gauging sensory representations in the brain. http://www.vcl.salk.edu/Publications/PDF/Buracas_Albright_1999_TINS.pdf</ref> and [[auditory system]] or be generated intrinsically by the neural circuitry.<ref name="Gerstner97">{{cite journal |vauthors=Gerstner W, Kreiter AK, Markram H, Herz AV |title=Neural codes: firing rates and beyond |journal=Proc.

Whether neurons use rate coding or temporal coding is a topic of intense debate within the neuroscience community, even though there is no clear definition of what these terms mean.<ref name=":0">{{Cite book|last=Gerstner, Wulfram.|url=https://www.worldcat.org/oclc/57417395|title=Spiking neuron models : single neurons, populations, plasticity|date=2002|publisher=Cambridge University Press|others=Kistler, Werner M., 1969-|isbn=0-511-07817-X|___location=Cambridge, U.K.|oclc=57417395}}</ref>
