Computational Neuroengineering is an advanced course offered to students of the master's degree in Computer Science aimed at providing the tools and methods for modeling the nervous system at different scales, from single neurons to complex neuronal networks
Understanding the computational mechanisms of the human brain is one of the greatest challenges of this century. Together with the experimental part, a great effort has been provided thanks to large-scale simulations, as well as by the development of theoretical models at different scales of observation.This course is centered on the use of computational techniques to model biological neural networks, but also to understand the brain and its function through a variety of theoretical constructs and computer science analogies.
Specifically, the emphasis is on neural information processing at “network level”, in developing quantitative models, as well as in formalizing new paradigms of computation and data representation. The course will provide insights about how the developing of in silico models, as well as of neuromorphic computational engines – based on the brain's circuitry – can contribute a better understand the coding strategies used by the “biological” brain to process incoming stimuli, and produce cognitive and/or motor outputs.
