Modern neuroscience sees the brain as an information-processing
device. Understanding how the brain processes information requires
understanding the representations used by the network of neurons that
compose the brain. However, representations in the brain are
distributed: each cell carries only a small portion of the total
information. I am interested in questions of how neural structures
work together to create systems able to accomplish behavioral tasks.
Our primary current projects are in the interaction between multiple
learning systems (such as
hippocampus, cortex, and striatum) in the ability to make decisions,
particularly deliberative decisions. We have ongoing
neurophysiological projects examining the dynamics of neural ensembles
during decision-making processes, computational projects examining
the implications of these processes on addiction and other
decision-making dysfunctions, and engineering projects developing new
