Computational neuroscience is the study of brain function in terms of the information processing properties of the structures forming the nervous system. It is an interdisciplinary science that links the diverse fields of Neuroscience, Cognitive science and Psychology with Physics, Mathematics, and Engineering.
The physiology and dynamics of functional and biologically realistic neurons within neural systems are the principal focus of computational neuroscience. Models capture the essential features of the biological system at multiple spatial and temporal scales: Membrane currents, protein and chemical coupling to network oscillations, columnar and topographic architecture and all the way to learning and memory processes. These computational models are used to frame hypotheses that can be directly tested for example in psychological experiments.
