Reduction of Excess Brain Activity Improves Memory in Amnestic Mild Cognitive Impairment
Research published by Cell Press in the May 10th issue of the journal Neuron, describes a potential new therapeutic approach for improving memory and modifying disease progression in patients with amnestic mild cognitive impairment. The study finds that excess brain [Read More]
Awake Mental Replay of Past Experiences Critical for Learning
Blocking it stumps memory-guided decision-making in rats – NIH-funded study Awake mental replay of past experiences is essential for making informed choices, suggests a study in rats. Without it, the animals’ memory-based decision-making faltered, say scientists [Read More]
Blocking “Oh-Glick-Nack” May Improve Long-Term Memory
Just as the familiar sugar in food can be bad for the teeth and waistline, another sugar has been implicated as a health menace and blocking its action may have benefits that include improving long-term memory in older people and treating cancer. Progress toward finding [Read More]
Chronic Stress Spawns Protein Aggregates Linked to Alzheimer’s
Repeated stress triggers the production and accumulation of insoluble tau protein aggregates inside the brain cells of mice, say researchers at the University of California, San Diego School of Medicine in a new study published in the March 26 Online Early Edition of [Read More]
Researchers Show that Memories Reside in Specific Brain Cells
Simply activating a tiny number of neurons can conjure an entire memory. Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the [Read More]
Researchers Partially Control a Memory
Scripps Research Institute Team Wrests Partial Control of a Memory The work advances understanding of how memories form and offers new insight into disorders such as schizophrenia and post traumatic stress disorder. Scripps Research Institute scientists and their colleagues [Read More]
Genetic Manipulation Boosts Growth of Brain Cells Linked to Learning, Enhances Effects of Antidepressants
Southwestern Medical Center investigators have identified a genetic manipulation that increases the development of neurons in the brain during aging and enhances the effect of antidepressant drugs. The research finds that deleting the Nf1 gene in mice results in [Read More]
Naked Mole Rats Bear Lifesaving Clues
Could blind, buck-toothed, finger-sized naked mole-rats harbor in their brain cells a survival secret that might lead to better heart attack or stroke treatments? University of Illinois at Chicago biologist Thomas Park and colleagues at UIC and the University of Texas Heath [Read More]
Memory Formation Triggered by Stem Cell Development
Researchers at the RIKEN-MIT Center for Neural Circuit Genetics have discovered an answer to the long-standing mystery of how brain cells can both remember new memories while also maintaining older ones. They found that specific neurons in a brain region called the dentate [Read More]
Researchers Develop Gene Therapy to Boost Brain Repair for Demyelinating Diseases
Our bodies are full of tiny superheroes—antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin—a material that forms a protective, insulating cape around the axons of our nerve [Read More]
