A new study has identified three psychological profiles that influence brain health, cognitive decline, and dementia risk in aging adults. Profiles with high protective traits, like purpose and openness, show better cognition and brain integrity, while those with low protective traits or high negative traits face accelerated brain atrophy and mental health issues.
Top 10 Neuroscience News Articles of 2023
Jan 2, 2024 · Summary: The year 2023 witnessed groundbreaking discoveries in neuroscience, offering unprecedented insights into the human brain. From animal-free brain organoids to the effects of optimism on cognitive skills, these top 10 articles have unveiled the …
Cells Beyond the Brain Show Surprising Memory Abilities
Nov 9, 2024 · Summary: New research reveals that cells outside the brain can store and process memories, challenging the view that memory is limited to neurons.Scientists found that non-brain cells, when exposed to spaced chemical signals, activated a “memory gene” similarly to neurons. This discovery suggests that learning from repetition could be a fundamental property of all cells.
AI Estimates Brain Age, Links Lifestyle to Cognitive Health
Dec 20, 2024 · Summary: Researchers used AI to analyze brain images from 70-year-olds, estimating their biological brain age and uncovering connections to lifestyle and health factors.Diabetes, inflammation, and high glucose levels were linked to older-looking brains, while regular exercise and healthy habits were associated with younger-looking brains.
AI Reveals Brain Oscillations for Memory and Disease
Mar 5, 2024 · Summary: A recent study showcases a significant leap in the study of brain oscillations, particularly ripples, which are crucial for memory organization and are affected in disorders like epilepsy and Alzheimer’s.Researchers have developed a toolbox of AI models trained on rodent EEG data to automate and enhance the detection of these oscillations, proving their efficacy on data from non ...

4 days ago · A study analyzing data from over 2 million veterans found that GLP-1 receptor agonists, popular weight-loss drugs like Ozempic and Wegovy, provide significant neurological and behavioral health benefits, including reduced risks of addiction, Alzheimer’s, and dementia.
Mapping How Aging Affects Different Brain Cells
Jan 5, 2025 · Summary: New research shows that not all brain cells age equally, with certain cells, such as those in the hypothalamus, experiencing more age-related genetic changes.These changes include reduced activity in neuronal circuitry genes and increased activity in immunity-related genes. The findings provide a detailed map of age-sensitive brain regions, offering insights into how aging may ...
Distinctive Neural Wiring Enhances Memory Storage
Dec 11, 2024 · Summary: A new study has revealed distinct features of the human hippocampus, a brain region critical for memory storage and retrieval, challenging the assumption that it functions like a scaled-up mouse brain.By analyzing living brain tissue from epilepsy patients, researchers found that human hippocampal CA3 neurons exhibit sparse yet highly reliable connections, optimizing memory storage ...
New Tech Maps Human Brain in Unprecedented Detail
Jun 13, 2024 · Summary: Researchers developed a technology pipeline to image entire human brain hemispheres at high resolution. This breakthrough allows for detailed analysis of brain structures, offering insights into diseases like Alzheimer’s. The study reveals how specific neurons are activated during sleep and how sleep deprivation impacts memory.
Brain-Targeted mRNA Delivery Breaks the Blood-Brain Barrier
Dec 17, 2024 · Summary: Researchers have developed lipid nanoparticles (LNPs) that cross the blood-brain barrier (BBB) and precisely target brain cells, a major step toward treating neurological diseases like Alzheimer’s.By attaching short peptides to LNPs, scientists achieved targeted mRNA delivery to neurons and endothelial cells, avoiding invasive procedures.
