Journal ArticleDOI
Serotonin and the Neuropeptide PDF Initiate and Extend Opposing Behavioral States in C. elegans
Steven W. Flavell,Navin Pokala,Evan Z. Macosko,Dirk R. Albrecht,Johannes Larsch,Cornelia I. Bargmann +5 more
TL;DR: A neuromodulatory circuit is characterized that generates long-lasting roaming and dwelling states in Caenorhabditis elegans that is orthogonal to the classical wiring diagram and contains several essential neurons that express each molecule.
Journal ArticleDOI
High-throughput imaging of neuronal activity in Caenorhabditis elegans
Johannes Larsch,Donovan Ventimiglia,Donovan Ventimiglia,Cornelia I. Bargmann,Cornelia I. Bargmann,Dirk R. Albrecht,Dirk R. Albrecht,Dirk R. Albrecht +7 more
TL;DR: It is found that behavioral variability is observed even when sensory responses are reproducible, and that sensitivity to specific odors varies among individual animals.
Journal ArticleDOI
A Circuit for Gradient Climbing in C. elegans Chemotaxis
Johannes Larsch,Steven W. Flavell,Qiang Liu,Andrew Gordus,Dirk R. Albrecht,Cornelia I. Bargmann +5 more
TL;DR: The adaptation-based circuit motif embodied by AWA and AIA shares computational properties with bacterial chemotaxis and the vertebrate retina, each providing a solution for maintaining sensitivity across a dynamic range.
Journal ArticleDOI
Biological motion as an innate perceptual mechanism driving social affiliation
Johannes Larsch,Herwig Baier +1 more
TL;DR: It is found that individual zebrafish shoal autonomously without evidence for a reciprocal choreography, revealing individual-level, innate perceptual rules of engagement in mutual affiliation and providing experimental access to the neural mechanisms of social recognition.
Journal ArticleDOI
MultiFocus Polarization Microscope (MF-PolScope) for 3D polarization imaging of up to 25 focal planes simultaneously
Sara Abrahamsson,Molly McQuilken,Shalin B. Mehta,Amitabh Verma,Johannes Larsch,Rob Ilic,Rainer Heintzmann,Cornelia I. Bargmann,Amy S. Gladfelter,Rudolf Oldenbourg +9 more
TL;DR: The MF-PolScope system employs multifocus optics to form an instantaneous 3D image of up to 25 simultaneous focal-planes and shows examples of 3D multi-focus polarization imaging of biological samples, including a protein assembly study in budding yeast cells.
