What is Computational Neuroscience Computational neuroscience is the study of brain function in terms of the information processing properties of the structures that make up the nervous system.

History Wilfrid Rall presented the first multicompartmental model using cable theory in 1960 The term "computational neuroscience" was introduced by Eric L. Schwartz in 1985 Wilfrid Rall presented the first multicompartmental model using cable theory in 1960 The term "computational neuroscience" was introduced by Eric L. Schwartz in 1985

7
Difference between computational and experimental neuroscience in terminology Computational neuroscience relies heavily on computer simulation and modeling and so is not, perhaps purely theoretical.

8
Computational neuroscience and neural computing Neural computing has become mainly concerned with technical applications of the theory, interested mainly in solving difficult engineering problems, while computational neuroscience has become mainly concerned with the application of the theory to understanding natural systems.

9
Aspects of representation Computational neuroscience has focused on two distinct aspects of representation temporal representation population representation Computational neuroscience has focused on two distinct aspects of representation temporal representation population representation

10
Temporal representation Temporal representation deals with how neurons represent time-varying signals

11
Population representation Population representation deals with issues of distributed representation.
