HEADLINE

MIT Neuroscientists Identify Universal Brain Signature Linking Diverse Anesthesia Drugs To Loss Of Consciousness

SUMMARY

A new study from the Massachusetts Institute of Technology reveals that while anesthesia drugs like propofol, ketamine, and dexmedetomidine have different molecular targets, they all cause the brain to lose "dynamic stability." This shared mechanism of neural destabilization could lead to the development of a universal automated system for monitoring and delivering anesthesia during surgery.
