D. Similarly, when people go for a few days without sleeping, they get sick.
E. The processes take place to stop our brains becoming loaded with memories.
F. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.
G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.
