Summary

Researchers have recently intricately dissected the BST's dynamic activities, its connection patterns and its functions with respect to specific cell types using multiple techniques such as optogenetics, in vivo calcium imaging and transgenic tools to unmask the complex circuitry mechanisms that underlie anxiety.

Usefulness & Problems

Published Workflows

Objective: Determine how chronic social trauma affects social reward and identify the lateral septum circuitry that mediates social reward occlusion in susceptible mice.

Why it works: The study first establishes a behavioral phenotype after chronic social defeat stress, then uses complementary activity-mapping and recording methods to identify a candidate neuron population, and finally perturbs that population and its downstream connections to test causal effects on behavior.

Stages

  1. 1.
    Behavioral phenotyping after chronic social defeat stress(functional_characterization)

    This stage establishes the social-trauma phenotype and separates susceptible mice from resilient or control mice before neural analysis.

    Selection: Identify susceptible mice that avoid juvenile social interaction and fail to develop context-dependent social reward.

  2. 2.
    Candidate circuit identification by activity mapping and recording(secondary_characterization)

    This stage narrows from behavioral phenotype to a candidate neural population using convergent mapping and recording methods.

    Selection: Identify neuron populations activated by juvenile social interactions specifically in susceptible mice.

  3. 3.
    Causal circuit perturbation(confirmatory_validation)

    This stage tests whether the identified NTLS population and its downstream connections are sufficient to modulate the behavioral outputs linked to susceptibility.

    Selection: Test whether manipulating NTLS neurons and their downstream connections changes social interaction and social reward.
