by Northwestern University Credit: Pixabay/CC0 Public Domain Scientists have long known the brain’s hippocampus is crucial for long-term memory. Now a new Northwestern Medicine study has found the hippocampus also plays a role in short-term memory and helps guide decision-making. The findings shed light on how the hippocampus contributes to memory and exploration, potentially leading to...
by Autonomous University of Barcelona Credit: Pixabay/CC0 Public Domain A research team from the Institut de Neurociències at the Universitat Autònoma de Barcelona (INc-UAB) has showed that inhibition of the Tac2 neuronal circuit, involved in the formation of the memory of fear, has opposite effects according to sex on the ability to remember aversive events in mice, reducing...
by UT Southwestern Medical Center Above illustration shows a neuron (green) ensheathed by an oligodendrocyte (purple) with “activated” genetic material (DNA) in each cell’s nucleus. Differences in each cell type’s active DNA may underlie human memory. Credit: Melissa Logies UT Southwestern scientists have identified key genes involved in brain waves that are pivotal for encoding memories....
UNIVERSITY OF MICHIGAN When you slip into sleep, it’s easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain. U-M researchers have been studying how memories associated with a specific sensory event are formed and stored in mice. In a study conducted...
by Alzheimer’s Research UK Example of the neuropsychological tests used to assess cognitive performance, including (a) Object-Recognition test (Modified Benton recognition task), (b) List-Learning memory test (Modified Rey auditory verbal learning test), and (c) List-Sorting task (List sorting working memory test from the NIH Toolbox Cognition Battery). Example stimuli for the ModBent (a) were generated in MATLAB (MathWorks,...

by American Academy of Neurology Credit: Unsplash/CC0 Public Domain Primary progressive aphasia is a rare neurodegenerative condition characterized by prominent language problems that worsen over time. About 40% of people with the condition have underlying Alzheimer’s disease. But a new study has found that people with the condition may not develop the memory problems associated with...
UNIVERSITY OF CALIFORNIA – SAN DIEGO Hearing loss and diabetes are major public health problems, with Latinos at higher risk than other demographic groups. In a new study published December 17, 2020 in the online issue of JAMA Otolaryngology-Head & Neck Surgery, researchers at University of California San Diego School of Medicine with colleagues elsewhere, report...
by Universitat Oberta de Catalunya A number of studies have shown how playing video games can lead to structural changes in the brain, including increasing the size of some regions, or to functional changes, such as activating the areas responsible for attention or visual-spatial skills. New research from the Universitat Oberta de Catalunya (UOC) has gone further...
Anticholinergic medications are used for many conditions but might also accelerate cognitive decline, especially in older persons with biological or genetic risk factors UNIVERSITY OF CALIFORNIA – SAN DIEGO A team of scientists, led by researchers at University of California San Diego School of Medicine, report that a class of drugs used for a broad...
