KING’S COLLEGE LONDON New research from King’s College London and The Open University could help explain why memory in old age is much less flexible than in young adulthood. Through experiments in mice the researchers discovered that there were dramatic differences in how memories were stored in old age, compared to young adulthood. These differences,...

Scientists link ‘hunger hormone’ to memory in Alzheimer’s study
UNIVERSITY OF TEXAS AT DALLAS Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the “hunger hormone” ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer’s disease (AD). The findings, based on observations of postmortem brain-tissue samples from Alzheimer’s patients and on experiments with a mouse model of AD, also...

New method classifies brain cells based on electrical signals
by Massachusetts Institute of Technology For decades, neuroscientists have relied on a technique for reading out electrical “spikes” of brain activity in live, behaving subjects that tells them very little about the types of cells they are monitoring. In a new study, researchers at the University of Tuebingen and MIT’s Picower Institute for Learning and...

Your nose knows when it comes to stronger memories
by New York University Memories are stronger when the original experiences are accompanied by unpleasant odors, a team of researchers has found. The study broadens our understanding of what can drive Pavlovian responses and points to how negative experiences influence our ability to recall past events. “These results demonstrate that bad smells are capable of producing memory enhancements in both adolescents...

How sleep and mood impact working memory
wo new studies assess how working memory — the memory we use on a day-to-day basis in decision-making processes — is affected by age, mood, and sleep quality and whether these factors impact memory together or on their own. Two new studies investigate how sleep quality, mood, and age affect a person’s working memory. Working...

Transcranial Magnetic Stimulation Improves Working Memory
Researchers from Duke University School of Medicine have found that magnetic brain stimulation can help improve working memory. They studied repetitive transcranial magnetic stimulation (rTMS), showing that it improved memory task performance in all ages of adults. Given that individuals with Alzheimer’s will more than double by 2050, rTMS may be a potential form of...
