Energy efficiency is like a budget

A note for The Half-Lesson, "Your Brain Is Not for Thinking," in Seven and a Half Lessons About the Brain by Lisa Feldman Barrett.
Some context from page 5‌ is:

You can think about energy efficiency like a budget.

Body-budgeting regions are shown in dark gray.

I introduced the idea of a "budget" for your body in my previous book, How Emotions are Made: The Secret Life of the Brain.[1] The scientific term for body-budgeting is allostasis.

The figure on this page shows the body-budgeting regions (dark gray) within the human brain's interoceptive system.[2]
