Topic description
The basal ganglia (BG) are involved in a wide range of motor and cognitive processes, and accordingly, their dysfunction can lead to several neurological diseases. Extensive experimental characterization at multiple scales of the BG in normal and pathological conditions have provided important insights about the BG. However, a coherent computational theory linking these observations to function has eluded the neuroscientists.
Bottom-up computational approaches have addressed the dynamical properties and interaction of the neural activity in the BG nuclei, while top-down approaches rather have described BG function inspired by machine learning algorithms.
In this workshop, we will discuss progress made in our understanding of the BG at multiple scales with the aim to bridge between bottom-up and top-down approaches. The main emphasis of the workshop will be to understand how the dynamics relate to function and dysfunction of BG. In addition, the workshop will foster an interaction between experimentalists and theoreticians.
