    • Bidirectional thermotaxis in Caenorhabditis elegans is mediated by distinct sensorimotor strategies driven by the AFD thermosensory neurons 

      Luo, Linjiao; Cook, N.; Venkatachalam, Vivek; Martinez-Velazquez, L. A.; Zhang, Xiaosong; Calvo, A. C.; Hawk, J.; Macinnis, Bronwyn Lee; Frank, Michelle Murrah; Ng, J. H. R.; Klein, Mason Joseph; Gershow, M; Hammarlund, M.; Goodman, M. B.; Colon-Ramos, D. A.; Zhang, Y.; Samuel, Aravinthan DT (Proceedings of the National Academy of Sciences, 2014)
      The nematode Caenorhabditis elegans navigates toward a preferred temperature setpoint (Ts) determined by long-term temperature exposure. During thermotaxis, the worm migrates down temperature gradients at temperatures above ...

    • Contrasting responses within a single neuron class enable sex-specific attraction in Caenorhabditis elegans 

      Narayan, Anusha; Venkatachalam, Vivek; Durak, Omer; Reilly, Douglas K.; Bose, Neelanjan; Schroeder, Frank C.; Samuel, Aravinthan DT; Srinivasan, Jagan; Sternberg, Paul W. (Proceedings of the National Academy of Sciences, 2016)
      Animals find mates and food, and avoid predators, by navigating to regions within a favorable range of available sensory cues. How are these ranges set and recognized? Here we show that male Caenorhabditis elegans exhibit ...

    • Local Thermometry of Neutral Modes on the Quantum Hall Edge 

      Venkatachalam, Vivek; Hart, Sean; Pfeiffer, Loren; West, Ken; Yacoby, Amir (Nature Publishing Group, 2012)
      Electrons in two dimensions and strong magnetic fields can form an insulating two-dimensional system with conducting one-dimensional channels along the edge. Electron interactions in these edges can lead to independent ...

    • Pan-neuronal imaging in roaming Caenorhabditis elegans 

      Venkatachalam, Vivek; Ji, Ni; Wang, Xian-Ling; Clark, Christopher Luce; Mitchell, James Kameron; Klein, Mason Joseph; Tabone, Christopher; Florman, Jeremy; Ji, Hongfei; Greenwood, Joel S.f.; Chisholm, Andrew; Srinivasan, Jagan; Alkema, Mark; Zhen, Mei; Samuel, Aravinthan DT (Proceedings of the National Academy of Sciences, 2015)
      We present an imaging system for pan-neuronal recording in crawling Caenorhabditis elegans. A spinning disk confocal microscope, modified for automated tracking of the C. elegans head ganglia, simultaneously records the ...

    • Single Electron Probes of Fractional Quantum Hall States 

      Venkatachalam, Vivek (2012-08-10)
      When electrons are confined to a two dimensional layer with a perpendicular applied magnetic field, such that the ratio of electrons to flux quanta \((\nu)\) is a small integer or simple rational value, these electrons ...
