Possibility of selectively erasing unwanted memories The human brain is exquisitely adept at linking seemingly random details into a cohesive memory that can trigger myriad associations -- some good, some not so good. For recovering addicts and individuals suffering from post-traumatic stress disorder (PTSD), unwanted memories can be devastating. Former meth addicts, for instance, report intense drug cravings triggered by associations with cigarettes, money, even gum (used to relieve dry mouth), pushing them back into the addiction they so desperately want to leave.
Why Time Slows Down When We’re Afraid, Speeds Up as We Age, and Gets Warped on Vacation by Maria Popova “Time perception matters because it is the experience of time that roots us in our mental reality.” Given my soft spot for famous diaries, it should come as no surprise that I keep one myself. Perhaps the greatest gift of the practice has been the daily habit of reading what I had written on that day a year earlier; not only is it a remarkable tool of introspection and self-awareness, but it also illustrates that our memory “is never a precise duplicate of the original [but] a continuing act of creation” and how flawed our perception of time is — almost everything that occurred a year ago appears as having taken place either significantly further in the past (“a different lifetime,” I’d often marvel at this time-illusion) or significantly more recently (“this feels like just last month!”). Discus chronologicus, a depiction of time by German engraver Christoph Weigel, published in the early 1720s; from Cartographies of Time.

Top 10 Best Astrophotographers in the World The sky that we usually see and is considered to be an ordinary thing is in fact full of many wonders and secrets that need to be revealed but how to do this? Discovering more about the secrets that are hidden in the sky is costly and requires spending a long time trying to see the invisible objects and observe the changes that take place in front of your eyes using special equipment. The question is how to record all what you see and the amazing beauty of the invisible objects that can be found in the sky to enjoy watching them whenever you want? It is the role of the astrophotographers who come to dazzle us with the photos that they capture and are considered by many people to be unbelievable because of the stunning beauty that can be found in them. Patience is highly essential for capturing exceptional photographs as you have to keep looking at the sky with your eyes wide open waiting for the right and most exciting moments to capture.
First evidence that fear memories can be reduced during sleep A fear memory was reduced in people by exposing them to the memory over and over again while they slept. It's the first time that emotional memory has been manipulated in humans during sleep, report Northwestern Medicine scientists. The finding potentially offers a new way to enhance the typical daytime treatment of phobias through exposure therapy by adding a nighttime component. Exposure therapy is a common treatment for phobia and involves a gradual exposure to the feared object or situation until the fear is extinguished. "It's a novel finding," said Katherina Hauner, a postdoctoral fellow in neurology at Northwestern University Feinberg School of Medicine.
The Science of Dreams and Why We Have Nightmares by Maria Popova The psychology of our built-in nocturnal therapy. “The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind,” Freud argued in his influential treatise The Interpretation of Dreams in 1900. “The earth is heavy and opaque without dreams,” Anaïs Nin wrote in her diary in 1940. Caduceus Coil The Caduceus Coil Also called the Smith Coil or the Tensor Coil The caduceus coil is well known to some branches of orthodox science but largely neglected, waved away and often relegated to what is referred to as the realms of pseudoscience and free energy irrationality. However, many electronic experimenters have reported that they have observed numerous properties unexplained by this very same science. What the following represents is a veritable ocean of unexplored possibilities. To reject such things purely on the basis of lack of theory, when others have built the hardware and seen it working, is a strange brand of science. A description of a caduceus coil by Wilbert Smith.

Drugs That May Cause Memory Loss Side Effect How they can cause memory loss: Benzodiazepines dampen activity in key parts of the brain, including those involved in the transfer of events from short-term to long-term memory. Indeed, benzodiazepines are used in anesthesia for this very reason. When they're added to the anesthesiologist's cocktail of meds, patients rarely remember any unpleasantness from a procedure. Midazolam (Versed) has particularly marked amnesic properties.
