Emotion and reward
Fear, drive and the value of things.

In the 3D app, the brain flies to each part as you read, and 2 quick questions at the end help it stick. Here is the whole lesson to read.
- 1
The alarm
The almond-shaped amygdala spots danger and gives memories their emotional punch.

Weighing the value
Above the eyes, the orbitofrontal cortex judges how much things are worth and helps you change course when they no longer are.
