New study of science discovered that why and how do we actually wake up in the middle of sleeping. Is it everything alright with my health? What if we will miss to sleep and we were not able to open our eyes again? It may seem strange, but there is a whole system in the body dedicated to this.
University of Oxford (UK) have discovered the mechanism by which people wake up, which, in their view, could explain the "mystery" of sleep, as published in the journal Nature.
The explanation continues, it could come from the second controller sleep, ie, the homeostatic clock, which measures something that happens in the brain when you are awake and asleep, though "not yet know what it is."
Experts found that when the dopamine system is activated, control neurons are disabled sleep and awakening occurs
Before this, scientists have analyzed the homeostatic sleep in the brain of the fruit fly, the animal that helped provide the first knowledge of the circadian clock. Each fly has around neurons that control sleep two dozen brain cells, which are also found in other animals and possibly in people.
Activation and inactivation of neurons
It is known that these neurons are active when you are asleep and inactive when you are awake. To study this process, scientists used photogenic technique, using pulses of light to display the activity of cells and tissues in living organisms. In this case, the production of dopamine stimulated to manipulate the activity of neurons sleep, as a switch.
Being able to manipulate the sleep switch has given us the opportunity to discover how it works
Experts found that when the dopamine system is activated, neurons control sleep are inactivated and the fly is awake, whereas when the supply of dopamine neuron control is activated sleep and therefore fly stops He is sleeping.
"Being able to manipulate the sleep switch has given us the opportunity to discover how it works. When neurons control sleep are active, there is an ion channel, which we have called 'Sandman', which controls the electrical impulses of these neurons and communicates with the brain cells we have mentioned. in addition, we found that when dopamine is present, 'Sandman' passes into the cell, causing a short circuit in neurons and off, leading to wakefulness "
