The brain is a fascinating structure and there are lots of moving parts activated during driving! The amygdala—a tiny almond-shaped structure in the temporal lobe of the brain—is a part of the limbic system that governs emotion, survival instincts, and memory. When you’re driving, the amygdala helps store memories of events and emotions so that you can recognize similar events in the future. It also helps you recognize familiar surroundings, such as buildings, and streets.
The amygdala is also activated when you feel emotions like anger, fear, or anxiety while driving. If you have a bad case of road rage, chances are the alarm bells in your amygdala are going off.
