In adult mouse cortical GABAergic Patch-seq neurons, out-of-fold channel-gene scores align positively with residual input conductance (median Spearman ρ=0.32; n=493), indicating reinforcement rather than compensation.
- Why it matters: It is unclear whether adult cortical neurons compensate for dendritic conductance load by changing channel expression or instead reinforce it, shaping how excitability is regulated.
- What they did: The study modeled rheobase as input conductance times an effective-voltage factor and used a sign-test framework with cross-fitting to relate channel-gene scores to residual input conductance (ρ=0.32; n=493) and morphology-predicted conductance (ρ=0.23; n=483).
- The result: The association is mainly in Sst and Pvalb cells and near zero in Vip cells, with a compensation-axis slope of 0.13 (excluding a population-wide compensation rule), and morphology-derived conductance predictions transfer to human reconstructions (ρ=0.27; n=128).
