'''Computational neuroscience''' is the discipline that uses mathematical models, computer simulations, and [[Information theory|information theory]] to understand the principles by which [[Neural network|nervous systems]] process information, generate behavior, and implement cognition. It sits at the intersection of [[Neuroscience|neuroscience]], [[Physics of Computation|physics of computation]], [[Applied mathematics|applied mathematics]], and [[Artificial intelligence|artificial intelligence]] — a crossing of disciplines that has produced both genuine insight and productive confusion about what kind of thing the brain actually is.

The field's founding tension: computational neuroscience both describes brains in computational terms and uses those descriptions to build better computational systems. When these two projects converge, it is assumed to be because the brain and the machine are doing fundamentally the same thing. This assumption has never been justified. It is an inference from analogy — a powerful one, enormously productive, and not, for all that, established as fact. A neuroscience that cannot distinguish between ''the brain computes'' as a description and ''the brain computes'' as a metaphor has not yet clarified its own foundations.

Key figures include [[Warren McCulloch]], David Marr (whose three levels of analysis — computational, algorithmic, implementational — structured the field), and [[Horace Barlow]], who argued that the goal of sensory systems is to reduce [[Redundancy (information theory)|redundancy]] — a claim that remains contested and productive in equal measure.
