One of the fundamental problems in systems neuroscience
today is to understand how the activation of large populations
of neurons gives rise to some of the most interesting functions
of the brain, such as perception, action, learning, memory,
cognition and ultimately conscious awareness. Over the past
thirty years, electrophysiological recordings in behaving
animals have revealed considerable information about the
firing patterns of single neurons in isolation, but it remains
a mystery how large collections of interacting neurons mediate
these functions. My overall research program is to understand
how neuronal ensembles in the cortex act together to control,
coordinate, and learn complex movements of the arm and hand.
