Your Body’s Own Cannabinoid Molecules Calm You During Stress
A new Northwestern Medicine study has discovered that a key emotional brain center, the amygdala, releases endogenous cannabinoid molecules under stress, and these molecules dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain.
