What is Computational Neuroscience?
Computational neuroscience is an interdisciplinary field that focuses on the development and application of mathematical models, computational algorithms, and simulations to understand the structure, function, and dynamics of the nervous system. By creating theoretical frameworks and integrating experimental data, computational neuroscience aims to provide a deeper understanding of the underlying principles of neural processing, brain function, and behavior.
Key Concepts and Techniques in Computational Neuroscience
