That just does not happen to us in a dream. Every now and then we run, or dance, to drive or swim, fly or fall. And our brain is also serious about what is happening in the dream, as in real life: the neurons to the motor centers are showing exactly the same activity as in the present movement.
Carrying around a third of life in a dream, we know very little offensively that happens to us at this time. The vast majority of people instantly forgets the vast majority of dreams after waking up. Not surprisingly, still do not even have a clear answer to the question, what dreams do exist ( for an interesting hypothesis on this subject you can read in our article ...
Recently, with very interesting results of sleep research were German neuroscientists Martin Dresler (Martin Dresler), Michael Tszhish (Michael Czisch) and their colleagues. Scientists are interested in using imaging to ... The difficulty, however, is that usually we do not control what is happening to us in dreams, for the very notable exception of lucid dreaming. In these rare sleep states understand that everything that happens to him only a dream, and retains some control over it.
Although it is believed that in one form or another state of lucid dreaming experience in a lifetime of about 50 % of the people, this happens on a regular basis with very few. Often, this can help achieve training and special equipment, including continuous writing down dreams, to highlight what is happening in the clear signs that allow to see what is happening with a person he only dreaming.
Six of these experienced dreamers and called to the aid of German researchers. Volunteers were asked to start compressing the left or right hand fixing the characteristic patterns of brain activity that occur at the same time. Then subjects had to go to sleep right in the tomograph, and then entered into a state of lucid dreaming, apply a signal to scientists, having made two eye movements from left to right. Of course, parallel to the dream state ( REM phase advance ) and objectively recorded by the characteristic waves of brain activity. Since then, the brain activity observed with the help of imaging ( in the whole volume of the brain ) and near-infrared spectroscopy ( on its surface ). The subjects had to repeat the movement with his hand in his sleep.
In such difficult conditions, only two of the volunteers were able to enter into a state of lucid dreaming. However, both of them were clearly recorded the activity of motor cortex, associated with the movements of the right or left hand, just one that was seen during wakefulness and. This allowed the researchers to an important conclusion about what happened to us in a dream not only exists in the form of ... We do not review the dream in the style of the movie, and completely, all just neurons, are immersed in what is happening.
It is also interesting that despite the activity of motor cortex, which controls the movement itself, the central region of the brain that are responsible for making fundamental decisions about the implementation of a movement, in a dream not to be activated. This may reflect the fact that dreamers realize that they are in a dream, really do not move.
The team now intends to Michael Tszhisha complicate and extend the experiments, gaining more experienced volunteers, covering a wider range of activities, including walking, talking, and even a flight.
