    Collapse Overview 
    Collapse overview
    We study the physiological processes regulated by native nicotinic acetylcholine receptors (nAChRs), a large family of ligand gated ion channel proteins. These receptors mediate key aspects of cholinergic signaling in the brain and are involved in several important cognitive processes, including motivated behavior, affective behavior, attention and learning/memory. Aberrant nAChR activity is linked to several neurological diseases/disorders, such as nicotine addiction, schizophrenia, major depressive disorder, Alzheimer's disease and Parkinson's disease. We use a broad range of techniques, including patch clamp electrophysiology, confocal and two-photon imaging, immunohistochemistry and behavioral approaches such as drug self-administration.

    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.
