But that might be about to change. There's mounting evidence that the stability of brain activity could indicate when a person is no longer still under, and enable people to do something about it. Anesthesiologist Alex Proekt and his team used grids of electrodes placed directly on the brain to record the activity of four monkeys as they lost consciousness under one of two common anesthetics. They then used computer modeling based on dynamical systems theory to test how stable this activity was
