Sleeping well appears to be one of the most important factors underlying success in learning! Why do we sleep? For many years, the physiological function of sleep has not been clear.
In most people's mind, sleep is associated with rest and time for mental regeneration. Restorative, protective and energy-conserving theories of sleep have been quite popular until quite recently, when it has become apparent that one long-lasting sleep episode with suppression of consciousness does not seem to be the right way for evolution to tackle depleted resources, toxic wastes, or energy conservation.
For example, muscles do not need to shut off completely to get rest. The critical function of sleep is dramatically illustrated in experiments in which rats chronically deprived of sleep eventually die usually within 2.
If you do not sleep, you die! In evolutionary terms, sleep is a very old phenomenon and it clearly must play a role that is critical to survival. Only quite recently, it has been proven beyond doubt that the function of sleep is related to learning not all scientists agree!
Researchers have long known about the importance of the hippocampus, a small brain organ, for memory formation. Yet it has always been difficult to find out what is special about the hippocampus that distinguishes it from other areas of the cerebral cortex that also show synaptic plasticity, i.
A collective effort of a number of researchers resulted in the proposition of the concept of neural optimization in sleep see the next section for a metaphorical explanation: Disk and RAM metaphor.
The hippocampus acts as the central switchboard for the brain that can easily store short-term memory patterns. However, these patterns have to be encoded in the neocortex to provide space for coding new short-term memories.
This complex process of rebuilding the neural network of the brain takes place during sleep. Unlike rest or conservation of energy, this highest feat of evolutionary neural mathematics requires the brain to be shut off entirely from environmental input in most animals!
This automatic rewiring is the main reason for which we sleep and why there is no conscious processing involved! It rewires its circuits to make sure that all newly gained knowledge is optimally stored for future use. We sleep so that the brain can integrate new knowledge and form new associations.
As we must sleep for our brain to continue its function, our body attached dozens of important processes to run in sleep as well.
In simplest terms, in waking we use and burn, while in sleep we restore and synthetize. Sleep affects the function and health of the entire body.
