    Collapse Overview
    Learning and movement are fundamental functions of the brain, yet many aspects of how these processes are orchestrated by various circuits remain elusive. Our group is trying to address several open questions about the neurobiological basis of reward-guided learning and movement in health and disease.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
