I suspect that the brain "fatigue" is caused by a preponderance of electrical "data" which needs to be processed and stored in order to clear the "active" brain much like in our computers. Too many open "windows" overloads the capacity of the synapses to move and organize the data. I am speaking informally here as a matter of common sense rather than science. But I think my analogy may be rather appropriate when the evidence is in... Interesting way of putting that theory. It does seem to be the favored theory, although I don't know the evidence that supports it. Evolutionarily, sleeps seems like a severe disadvantage. It makes the organism seriously vulnerable to attack for a good portion of the day. It must serve an important purpose. One of the things I've tried to find out and haven't is where in the animal phyla and classes it begins. It seems true of all mammals? How bout birds? Reptiles? Vertebrates? From my understanding of brain functioning the two primary active processes are electrical activity within the neurons and the chemical transmitters comprising the synapses. During normal daily activity the synapses degrade due to loss of protein. Without frequent regeneration and provision of fresh protein the brain would cease to function. Research shows that protein in the brain is indeed increased during sleep. I strongly suspect that this is the primary purpose of sleep, although no one seems to know for sure if there are other purposes. ........................................................... As to the purpose of sleep/dreaming, I don't remember any firm conclusions being arrived at. ...................................................... Although there are people (that are exceedingly rare) who appear not too need sleep at all. Also, it's hypothosized that meditation provides a good alternative to sleep and if proficiently practised cuts down the time a person needs for sleep considerably. sciforums.com TILT!
