They are regarded as special markers of human identity, even more individualized than DNA．But new research suggests our brains have “fingerprints” that are equally unchanging and unique to each person. With modern neuroimaging (神经影像) techniques, scientists can track your brain’s distinct signature composed of tens of thousands of electrical signals that communicate across the brain. The final product is a picture of brain’s electrical activity that is detailed, distinct and difficult to change. According to Zack Y. Shan, head of the neuroimaging platform at the Thompson Institute, “The brain is a symphony orchestra (交响乐团).” Each region plays a unique instrument and adapts to work with nearby tunes at the same time. This cooperation leads to our thoughts and actions. “And no two symphonies sound exactly alike,” Shan adds. A recent study published in Sleep maps the extent of this neurodiversity through EEG snapshots (脑电图快照), which describe the sleeping brain’s electrical activity as wavy lines. Led by Michael Prerau, a professor of medicine at Harvard Medical School, the researchers analyzed brainwave data of sleep spindles, one to two seconds evident neural activity associated with our ability to turn short-term memories into long-term memories. For Dara S. Manoach, a co-author of the Sleep study and professor of psychology at Harvard Medical School, the sleeping brain is a “new frontier” for studying the treatment of memory problems in neurological disorders. She notes that lack of sleep spindle activities has been linked to different mental diseases like epilepsy and Alzheimer’s disease. So, the researchers compared two nights of sleep recordings from healthy participants to those with Alzheimer’s disease. Their analysis revealed that their broadened approach to analyzing sleep spindles also could unearth new b
