The human brain is a complex system built, among other components, from billions of neurons. Understanding such a complex system requires insight into how the individual elements work (Cellular and Molecular Neuroscience), how they cooperate to provide particular functions (Systems Neuroscience), how the brain supports cognitive functions (Cognitive Neuroscience), what computations are implemented by the brain and how these computations are implemented biophysically (Computational Neuroscience), and how the nervous system develops (Developmental Neuroscience). Research at the UC Davis Center for Neuroscience covers all of these levels of analysis to provide a comprehensive understanding of the function of the nervous system (see Research Topics).
