Published Workflows

Objective: Identify neural circuitry that integrates prior pathogen exposure to modify learned avoidance behavior in Caenorhabditis elegans.

Why it works: The paper states that compressed sensing made an otherwise infeasible systematic screen efficient, and that calcium imaging plus optogenetic perturbations then determined neural dynamics for a key behavioral transition.

Stages

  1. 1.
    Compressed sensing-based circuit screen(broad_screen)

    This stage exists to make systematic circuit screening feasible and efficient in the learned pathogen avoidance context.

    Selection: Determine roles of individual neuron types in learned avoidance behavior.

  2. 2.
    Mechanistic analysis of stalled re-entry(functional_characterization)

    This stage exists to move from screen-level neuron identification to mechanistic understanding of one key behavioral transition after infection.

    Selection: Determine neural dynamics regulating stalled re-entry into bacterial lawns after infection.
