They then took an afternoon nap. This phenomenon only occurred during certain sleep phases, but not when the participants were awake. The brain reactivated the activity patterns - both for images the participants later remembered and for those they later forgot.The decisive factor in whether https://www.wooddryingkiln.com an image was forgotten or retained was not the reactivation of the image-specific gamma band activity, but the activity in a brain region that is important for memory: the hippocampus. One result: During sleep, the brain even reactivates memory traces that it can no longer remember later on.Only when the gamma band activity from the deep processing phase was reactivated during the ripples did the participants later remember the image.
If the activity from the early processing phase was reactivated, the image was forgotten.Specifically, whether an image is remembered or not depended on another factor, namely how detailed the image was processed in the brain. Hui Zhang..The full findings are present in the journal- Nature Communications.Washington DC: Sleep helps to consolidate memories, as per a new study. When looking at a picture, the activity in the brain shows a pattern that differs somewhat from picture to picture.This region shows extremely rapid fluctuations in activity, called ripples.Researchers from Ruhr-Universitat Bochum and the University of Bonn have investigated which activity patterns occur in the brain when people remember or forget things.For the experiment, the test participants were given a series of pictures to memorise.They analysed brain activity not only during the learning task but also during sleep.
They then tested which images the participants could remember after sleep and which they could not. They were interested in how the brain replays and stores during sleep what it had learned before. The researchers differentiated the gamma band activity measured when viewing the images into a superficial and deep processing stage. "The forgotten images do not simply disappear from the brain," said Dr.The team recorded the brain activity of epilepsy patients who had electrodes implanted into their brain for the purpose of surgical planning. A picture was only recalled later on when the reactivation occurred at the same time as the ripples in the hippocampus.The gamma band activity that was typical of certain motifs occurred not only when looking at the images, but also during sleep. The researchers were able to measure these differences in high-frequency activity fluctuations - called gamma band activity.
