Title: Neural codes and stimulus space structure
A major problem in neuroscience is to understand how the brain uses neural activity to form representations of the external world. It is known that combinatorial information in the firing patterns of neurons often reflects important features of the stimuli which generated them. How can we efficiently extract such information? We will consider methods both algebraic and topological for encoding and extracting combinatorial structure from neural codes, and also discuss how this structure can be used to uncover principles of neural coding, and to infer topological features of the underlying stimulus space.
