One of the most important unresolved questions in neuroscience is how memories are encoded and stored in the brain. Motor learning differs from other forms of learning, in which repetitive training and practice is required in order to achieve highly skilled and reproducible movements. Our lab employs a novel forelimb lever-press task for head-fixed mice, permitting us to perform chronic structural and functional two-photon imaging in awake and behaving mice. We aim to elucidate the molecular mechanisms underlying learning-driven neural circuit modifications, with spatial precision and cell subtype-specificity, during the formation of new motor memories in the awake brain.
