If I cannot build it, I do not understand it - Richard Feynman, Nobel prize in physics
The biology of the brain and the nervous system in general, or neurobiology, is a fascinating field. So is the related and very similar discipline of neuroscience. Evidently, with technological advances, computers began to take place in the elucidation of these highly complex matters. Therefore, the aim of the present section is a brief overview of the derivative sub-discipline of computational neuroscience.
Computational neuroscientists build artificial models that attempt to mimic brain functions. Sounds like artificial intelligence? Maybe, but, arguably, science is still only working towards that goal. Although, of course, it all depends on the definition one accords to intelligence. After all, today's machines can read, write, speak, count and perform many other complicated tasks necessitating processes akin to cognition and other mental feats in human.
Interestingly, according to Granger (2001), the neuroscientific branch is about more than computers per se or their working models, but about constructing simulacra of cortical activity. Amazingly, the author suggests that in time these theories would even permit the generation of prosthetic brains!

Further, the ideology relies on a set of principles such as that neural systems rely on stochastic differential equations (Carillo et al., 2011). Rolls (2011) places the historical beginning of the collection of theoretical constructs around the 1970s, with mathematician David Marr as one of the first contributors.
