Everyone the neocortex fires during sleep, it

Everyone has dreams but researchers still do not completely understand why we have dreams, or how dreams come about. For how common and often they occur, dreams still remain a complex mystery to this day and scientist aren’t certain why. Scientists have theories that dream serve to clearing the days useless memories and catching the valuable ones. They also speculate that dreams console important information and keep us alert when danger is near. Dreams date back 5,000 years ago to the ancient Egyptians, where they thought dreams were simply a different form of seeing. They would train dreamers that would serve as seers to help plan battles and make state decisions based off what they saw in their previous dreams. Although this is not a scientific approach, they reveal humans long-held desire to explore the depths of the dreaming mind. One thousand years ago, Tibetan Buddhist monks practiced a form of lucid dreaming known as Dream Yoga. They would use this to study the depths of human consciousness and use it as a path to enlightenment. In the 1600s a French philosopher Rene Descartes thought that our dreams provide evidence that our reality is not and scientist are now able to accurately test their theories and According to the New York Times, psychologists and neurologists, have equipment including PET scans and MRIs to take things to a deeper and more technical level. They speculate by saying that dreaming is the brain’s way of dumping excess data, consolidating important information and keeping us alert to danger. In 2007 a study as the neocortex fires during sleep, it signals various regions in the hippocampus to upload whatever information they’ve been holding in short-term storage. The hippocampus is then cleared to gather more the next day, while the neocortex decides what to transfer to long-term memory and what to discard. When the data streams on the computer screen of the sleeping mind, some of it gets snatched up and randomly stitched into the crazy quilt of dreams, which often only vaguely resemble the literal content of the information.” (Tierney)From the information gathered from the New York Times article, the signals various regions in the hippocampus to upload information, and the neocortex decides what to transfer to long-term memory and what to discard; it does not provide a method as to how the experiment Finally, they do not provide any additional evidence or separate sources to back up their accusations. They state what they perceive to be true, and no other further information or studies to confirm theirs. Although the Max Planck Medical Institute performed testing and gathered information for their study, they do not provide the methods that they performed or how the experiment for it, rather than giving factual evidence and other sources to prove their accusations and findings.
