Recuperative Functions of the Brain

The laws of similarity of sleep across the animal would indicate universal function. Sleep serve some primordical use. For example, rats deprived of sleep die faster than those deprived of food. Humans, too, have an indisputable drive to sleep so much so that we miss it, we make up for the loss by sleeping deeper and longer the next opportunity we get. Add to that breakthrough just eight years ago that fruit flies sleep up to 12 hrs a day.

It is contended that a possibility of sleep must account for the unbelievable fluctuation in sleep forms across animal world. There is a huge range in the amount and type of sleep. Bats and opossums sleep for 18 to 20 hrs a day, while elephants and giraffes sleep only 3 to 4 hrs a day. Generally herbivores sleep not as much as omnivores, who sleep not as much as carnivores.

This makes sense if we consider how these animals live on. If a cat in the wild kills and eats an antelope, what use is passing more time prowling around? It might likewise save its free energy. For grazing animals, then again, it is dangerous not to be alert for a long time. If sheep slept really deep, they would be out.

It is learned that right after dolphin mother gives birth, neither she nor her new sprung sleep for significant amounts. The infants then bit by bit increase their sleep to adult levels over a time period of months, and the mothers go back to their steady sleeping pattern half of the brain at once. Astonishingly, it is the opposite of what researches worker see in land mammalians, which sleep the most as newborns and step by step lessening sleep time as they age.

What we are seeing in maritime mammalians that have brains as large and larger than ours, is that they can go without sleep or much sleep for very a long time. It seems that animals conformed a system of rules of sleep to fit their environs so co-opted that rest time for functions more expeditiously.

Why does a fruit fly with its smaller brain and learning mental ability need more sleep than humen being? We have to think in proportional terms. A fruit fly likely tones up a larger fraction of its nerves cell in a day than a person and therefore needs more sleep.
