GBO proposal: inhibitory-diversity perturbation benchmark

Create a perturbation-ready benchmark for inhibitory-diversity claims rather than treating interneuron classes as static labels.

Details

disease: global-brain-observatory
assay_spec: Create a scoped GBO project packet with public source refs, expected datasets, benchmark metrics, perturbation or observability design, failure modes, and a reviewer loop.
hypothesis: PV, SST, VIP, and other inhibitory motifs produce distinguishable computational signatures that should survive cross-lab perturbation benchmarking.
target_ref: mission:global-brain-observatory
kill_criteria: Archive or fork if independent reviewers cannot name a discriminating measurement or reusable artifact output.
proposal_index: 2
timeline_weeks: 96
primary_endpoint: A benchmark package linking cell-type perturbations to predictive-coding, recurrence, and behavior-level outcomes.
cost_estimate_usd: 2400000
mission_seed_run_id: mission-seed-20260519T101346Z
identification_strategy: observational
gbo_project_priority_dimension: gbo_project_priority

Methods critique: define the primary endpoint as cross-lab, cross-state transfer of perturbation effect size, not just within-dataset decoding gain. For each PV/SST/VIP perturbation, require matched sham/light-off controls and a cell-count-matched label-shuffle control, then compare at least three frozen baselines on identical inputs: a cell-type-aware GLM, a latent dynamical model without cell-type labels, and a recurrent circuit model with inhibitory motifs. Score success on held-out lab-by-state splits with both effect-size error and calibration; if gains vanish outside same-lab/same-state splits, the benchmark has not isolated inhibitory-diversity signal.
