Slow-wave sleep engages brainstem circuitry to prevent stress-induced anxiety.

Slow-wave sleep engages a PZ GABAergic to LPB CGRP to ovBNST Crh circuit that prevents stress-induced anxiety in mice.

• Why it matters: Understanding how sleep reduces anxiety can inform treatments for anxiety disorders, addressing a gap in knowledge about sleep's neural mechanisms.
• What they did: The study used optogenetics, multi-region Ca2+ recording, and circuit analysis to identify a PZ GABAergic to LPB CGRP to ovBNST Crh pathway involved in sleep-related anxiolysis in mice.
• The result: Activation of this circuit induces SWS and prevents anxiety, suggesting it as a potential target for therapeutic intervention in anxiety disorders.
