Alzheimer’s Disease: Researchers Found Where Brain Stores Memories’ Time and Place
Scientist have found evidences of where the brain records the place and time of real-life memories. In a study published in Proceedings of the National Academy of ScienceOhio State University researchers showed that the brain patterns related to the activation of this specific region when memories were recalled were a clear indicator of the time and space between events. This could represent a significant advance for Alzheimer's disease. Each participant carried a smartphone app that was placed around their neck and took random photos for about a month. Later, participants were analyzed under an fMRI scanner and researchers noticed that when subjects relived the memories related to the photographs, a region of the brain’s hippocampus kept information of when and where they occurred. Moreover, the further apart those memories occurred in time and space, the further apart their representations appeared in the hippocampus. Per Sederberg, an assistant professor of psychology at Ohio State and senior author of the study, said in a news release, “What we’re picking up here is not the whole memory, but the basic gist – the where and when of the experience. This could be viewed as the memory hub, where we have these general, large-scale representations of our experiences.” So far, the majority of the work carried out in this field has been preformed using laboratory rats, though some human studies have also been developed. “We found that the hi
