Memory loss from West Nile virus may be preventable

More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain’s ability to repair damaged neurons and

Brain activity ripples linked to creation of long-term memories

While we’re asleep, the brain is working to store new information as long-term memories. Storing a memory likely involves interactions between the brain’s hippocampus and parts of the cortex. Scientists have been trying to determine the precise connections by examining electrical activity within these regions of the brain. When hundreds or thousands of nerve cells,

Memory For Details Matures Gradually

In contrast to previous assumptions, the hippocampus, a brain structure that is central to learning and memory, does not complete its maturation until adolescence. Scientists of the Max Planck Institute for Human Development, the Max Planck UCL Centre for Computational Psychiatry and Ageing Research, and the University of Stirling were able to show this for

Serotonin Loss May Drive Cognitive Decline

Loss of the neurotransmitter serotonin may drive cognitive decline rather than simply being a by-product of memory problems, according to new findings that have potential implications for the prevention and treatment of mild cognitive impairment (MCI). Studies have consistently shown that serotonin degeneration occurs in normal aging and Alzheimer's disease (AD), but evidence for degeneration

Even Moderate Alcohol Consumption May Harm the Brain

Source: Even Moderate Alcohol Consumption May Harm the Brain - Medscape - Jun 07, 2017. By Fran Lowry Moderate drinking is associated with pathologic findings in the brain, including hippocampal atrophy, vs no drinking, new research shows. Higher alcohol intake also predicted faster decline in cognitive measures of lexical fluency, although not semantic fluency or word recall, researchers found. "In this

Possible new weapon against PTSD

Blocking a newly identified memory pathway could prevent the disorder. Anne Trafton | MIT News Office August 31, 2015 About 8 million Americans suffer from nightmares and flashbacks to a traumatic event. This condition, known as post-traumatic stress disorder (PTSD), is particularly common among soldiers who have been in combat, though it can also be

Newly discovered brain network recognizes what’s new, what’s familiar

Network has broad role in memory, learning processes, study suggests August 13, 2015 By Gerry Everding WUSTL GRAPHIC / ADRIAN W. GILMORE The Parietal Memory Network, a newly discovered memory and learning network shows consistent patterns of activation and deactivation in three distinct regions of the parietal cortex in the brain’s left hemisphere — the

Sleep Links Memories, Drives Immunity, Hikes Height—and More

Tue, 06/02/2015 - 9:41am Cynthia Fox, Science Writer Sleep is critical for formation of memories. (Source: Wikimedia)As we spend one-third of our lives asleep, it better be for a good reason, actor and science host Alan Alda said at the World Science Festival (WSF) in New York City last week.It is. According to sleep specialists

Researchers find “lost” memories

Scientists use optogenetics to reactivate memories that could not otherwise be retrieved. Helen Knight | MIT News correspondent May 28, 2015 Illustration: Christine Daniloff/MIT Memories that have been “lost” as a result of amnesia can be recalled by activating brain cells with light. In a paper published today in the journal Science, researchers at MIT

Food for thought: Master protein enhances learning and memory

Salk scientists discover a single protein that energizes both muscles and the brain April 07, 2015 LA JOLLA–Just as some people seem built to run marathons and have an easier time going for miles without tiring, others are born with a knack for memorizing things, from times tables to trivia facts. These two skills–running and
