[Learning strengthens some connections between neurons, known as synapses, and even forms new synapses. These synapses demand a lot of extra energy, though.] That means that at the end of the day, you have a brain that costs you more energy, ... That's where sleep would kick in.
The brain breaks down into little islands that can't talk to one another.
They rest for 10 hours a night, and if you keep them awake longer, they need to sleep more.
The flies surprised us with how close they were in many ways.

[But why does consciousness fade during deep sleep early in the night?] You cannot say that consciousness fades because the brain shuts off. That's not the case. Scientists have long known that the brain remains active while we sleep, ... So what could be responsible?
That means that at the end of the day, you have a brain that costs you more energy. That's where sleep would kick in.
Essentially, we activate an area, ... We can do this anywhere in the brain. Once an area is activated, it responds by sending signals, waves that travel through the axons (nerve fibers) to other regions of the brain. At the same time, we can record how the rest of the brain is responding.
