Wearable scanner opens new frontier in neuroscience. A rat's head fits in the circular opening of this device, which is surrounded by miniaturized detectors and electronics (photo credit: Brookhaven National Laboratory) A tiny wearable positron emission tomography (PET) scanner has been used to track chemical activity in the brains of unrestrained animals while an animal behaves naturally; it could be modified for people.
By revealing neurological circuitry as the subjects perform normal tasks, researchers say, the technology could greatly broaden the understanding of learning, addiction, depression, and other conditions. A conventional PET scanner is so large that these studies have to be performed with the subject lying inside a large tube. Thinking & Learning. Accelerated Learning. Neurology. Neuroscientists reveal magicians' secrets - Technology & science - Science - LiveScience. NEW YORK — There is a place for magic in science.
Five years ago, on a trip to Las Vegas, neuroscientists Stephen Macknik and Susana Martinez-Conde realized that a partnership was in order with a profession that has an older and more intuitive understanding of how the human brain works. Magicians, it seems, have an advantage over neuroscientists. "Scientists have only studied cognitive illusions for a few decades. Magicians have studied them for hundreds, if not thousands, of years," Martinez-Conde told the audience during a recent presentation here at the New York Academy of Sciences. [ Video: Your Brain on Magic ] Perfect Pitch - Psychologists Find Perfect Pitch More Common in. Eidetic memory -photographic memory. Overview The ability to recall images in great detail for several minutes is found in early childhood (between 2% and 10% of that age group) and is unconnected with the person's intelligence level.
 Like other memories, they are often subject to unintended alterations. The ability usually begins to fade after the age of six years, perhaps as growing vocal skills alter the memory process. A few adults have had phenomenal memories (not necessarily of images), but their abilities are also unconnected with their intelligence levels and tend to be highly specialized. In extreme cases, like those of Solomon Shereshevsky and Kim Peek, memory skills can actually hinder social skills.
