Biography

Rafal Bogacz obtained an interdisciplinary training during his doctoral and postdoctoral studies. He conducted his PhD at the University of Bristol jointly in the Departments of Computer Science and Anatomy, and next he worked as a postdoctoral researcher at Princeton University jointly in Departments of Applied Mathematics and Psychology. In 2004 he came back to Bristol where he worked as a lecturer and then a reader. He moved to University of Oxford in 2013.

Research Summary

My research is in the area of computational neuroscience, which uses mathematical models to understand how computations in neural circuits give rise to human and animal behaviour. My work focuses on the computational models of brain circuits underlying action selection and decision making. These circuits include a set of subcortical nuclei known as the basal ganglia, which has been intensively studied because it is affected by Parkinson’s disease. Although many questions remain open, the anatomy and the neural activity in the basal ganglia has been characterized to the extent that allows formulating a formal mathematical theory describing how it selects actions in the healthy brain, and how the pathological patterns of activity observed in Parkinson’s disease are generated.

My research concerns models of basal ganglia in both health and disease. I investigate how the cortico-basal-ganglia-thalamic network selects actions on the basis of noisy sensory inputs, and whether this network can perform statistically optimal action selection. I also study in which part of this network and under what conditions, the excessive oscillations in activity are generated in Parkinson’s disease.
