Can the brain become 'tired'?

[Gnisy]

I just read something in a book that suggests that the brain is incapable of getting tired. What really gets tired is the muscles around the eyes or the neck and that is what actually makes us feel incapable of continuing whatever it is we were doing. Can anyone clarify this pls?

iI think maybe yout right and the brain is probably incapable of becoming tired. One possible explanation could be that it doesnt get tired not because it is impossbile, but because the muscles in our body become tired first.

The brain can however be overloaded, either by the quantity or quality of work it has to process.

i disagree. try staying awake for 2 days and try to do a simple maths problem. it is true that your body gets tired before your brain and during slep parts of the brain use less than normal energy while others use more. this suggests that the brain as a whole doesnt get tired but then again in a question like this the brain cant be viewed as a single organ. instead look at the individual regions of the brain which diffinately get tired.

Actually, several studies have shown that the one organ (were talking humans here) that receives the most benefit from sleep is the brain. The cerebral cortex operates differently, as measured by electroencephalograms (EEG), when asleep than when the body is completely relaxed in a darkened, soundproofed room. There is a marked difference in electrical activity. Additionally, it's a little known fact, that animals that hibernate must, periodically rouse from hibernation to sleep! This strongly suggests that sleep must serve some vital function other than just energy conservation, even for these less cerebrally advanced mammals... (Source: Killduff, et al). It's the brain and behaviour (especially the cerebral cortex) for which sleep seems to be the most vital. (Partial thanks to Jim Horne,The Phenomena of Human Sleep)
