Why AI Cannot Replace the Transformative Power of Human Creativity
Summary: As generative artificial intelligence masters the rapid synthesis of complex paintings, music, and literature, a new theoretical framework published in AI & Society re-evaluates the true essence of human…
Resetting Interneuron Timing Rescues Memory in Alzheimer’s
Summary: Researchers at Gladstone Institutes have decoded how parvalbumin (PV) interneurons generate gamma oscillations—the fast brain waves essential for attention and memory—by firing in precise, successive waves rather than all…
Higher BMI Linked to Longer Survival After a Dementia Diagnosis
Summary: A long-term study of more than 4,500 older adults reveals that individuals who are overweight or obese when diagnosed with dementia exhibit a significantly lower risk of death than…
Adults With ADHD Face Higher Long-Term Dementia Risk
Summary: A massive study of more than 187,000 older adults enrolled in the NIH’s All of Us Research Program reveals that adults with attention-deficit/hyperactivity disorder (ADHD) face more than quadruple…
Early DBS Protects Cognition in Genetic Parkinson’s
Summary: A multi-center international study reveals that the timing of Deep Brain Stimulation (DBS) surgery is the deciding factor in preserving cognitive function for Parkinson’s disease patients carrying a GBA1…
Could Your Voice Reveal How Fast Your Brain Is Aging?
Summary: A multicenter study of nearly 3,000 individuals published in Science Advances reveals that machine-learning models can infer a person’s biological age and brain health from vocal patterns. This newly…
Central Genetic Switch Controls Long-Distance Axon Navigation
Summary: Challenging the dogma that growing axons navigate exclusively via local cues processed at their tips, neuroscientists have discovered that a centralized genetic switch inside the neuron’s cell body directs…
Brain Activity Predicts Risky Choices Half a Second Before They Are Made
Summary: By recording directly from electrodes implanted in the human orbitofrontal cortex, neuroscientists discovered two neighboring circuits locked in a millisecond-by-millisecond “tug-of-war” between taking a risk and playing it safe.…
