What it means
It accounts for around two percent of body mass and roughly twenty percent of resting energy use, and the consumption barely changes between hard thinking and daydreaming. Most of that budget goes on maintaining the electrical gradients across neuron membranes, which is the standing cost of being ready to fire rather than the cost of any particular thought.
The claim comes from PNAS.
