A prefrontal microcircuit computes trial-wise discount of reinforcement during threat learning in male mice
The Brief
- A study in male mice identifies a prefrontal circuit that constrains early threat learning.
- The circuit involves local inhibitory neurons and computes trial-wise discounting of reinforcement during threat learning.
- The paper was published online in Nature Communications on 12 November 2026.
Why it matters
It maps a specific prefrontal circuit mechanism behind how threat learning is held in check early on, which may inform future work on fear learning. The findings come from male mice only.
