Overview
Our lab asks how light drives functions that are as diverse as visual perception and setting of the internal body clock. We pose this question for different species to learn how visual mechanisms are tailored to distinct needs. Our research spans organizational levels and time scales, from molecules to circuits and from milliseconds to hours. We focus on the retina and brain, relying primarily on electrophysiological and optical techniques applied in vitro and in vivo.

Visual performance is remarkable. Perception can be elicited by a small number of photons, yet continues when light has intensified by many orders of magnitude. How is this dynamic range established? In cases of severe blindness where visual awareness is lost, light can still synchronize the body clock with the solar day. What are the origins of this robustness?

Such questions of system function apply throughout biology. Posing them in the visual system is advantageous because the input, light, is precisely controllable and the outputs, such as the patterns of impulses sent from the eye to the brain, are often given to quantification. Thus, the intervening operations and their suitability to the organism can be made especially clear.

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.
