# Nervous System Regulation **Domain:** Neuroscience / Adaptation / Recovery **Doc Type:** Canonical concept node **Maturity:** Developed ## Definition Nervous system regulation is the ongoing adjustment of arousal, attention, defensive response, and recovery in relation to internal and environmental conditions. ## Mechanism and Significance Repeated danger can tune a system toward earlier and stronger alarm, while safety, practice, supportive relationships, and appropriate care can broaden the responses available under stress. ## Evidence Boundary Regulation is not a moral test or a demand for composure from harmed people. Persistent dysregulation can require clinical, social, and material support. ## Relationships [[wiki/Biological Cybernetics|Biological Cybernetics]] · [[wiki/Neuroplasticity|Neuroplasticity]] · [[wiki/Feedback Control|feedback control]] · [[wiki/Embodied Cognition|Embodied Cognition]] ## Related Articles and Collections - [[collections/Simple Reminders|Simple Reminders]] - [[articles/Analog Cognition and the Architecture of Continuity|Analog Cognition and the Architecture of Continuity]] - [[articles/Thank You for Your Attention to This Matter!|Thank You for Your Attention to This Matter!]] ## Simple Reminders, Quotations, and Thoughts > “A nervous system trained by danger may react early and intensely. That reaction is an adaptation, and it can be updated through safety, practice, and support. Recovery widens the range of available responses.” > **— Bryant McGill**, *Inner Wounds, Nonverbal Signaling, and the Work of Confidence - Livestream (Jan 2016)* [[reminders/Human Animality/Safety and Practice Can Update a Nervous System by Bryant McGill|Safety and Practice Can Update a Nervous System by Bryant McGill]]
