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.…

Adaptive Deep Brain Stimulation Fixes Parkinson’s Walking Gait
Summary: Researchers developed a closed-loop deep brain stimulation (DBS) system that reads and responds to human walking patterns in real time. While conventional DBS delivers a rigid, unyielding wave of…
Less Experience Leads to Faster Neural Adaptation
Summary: For over a century, the cornerstone of psychology has been the Pavlovian idea that we learn through repetition—the more a bell rings before food, the stronger the association. However,…
What Triggers Tantrums? Sensory Overload May Be To Blame
Summary: New research reveals a distinct brain activity signature in children who become overwhelmed by sensory input such as noise, touch, or bright lights. Using functional MRI, scientists found that…
Clues in Spinal Fluid Could Unlock Early FTD Diagnosis
Summary: Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified…
AI-Powered Brain Implant Lets Paralyzed Man Control Robotic Arm
Summary: A new brain-computer interface (BCI) has enabled a paralyzed man to control a robotic arm by simply imagining movements. Unlike previous BCIs, which lasted only a few days, this…
Low-Normal B12 Levels Linked to Slower Brain Processing
Summary: Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically…
Early Inflammation Linked to Midlife Cognitive Decline
Summary: A new study finds that higher inflammation in young adulthood is associated with reduced cognitive function in midlife. Researchers discovered that inflammation due to factors like obesity and smoking…
Women’ Life Expectancy Six Years Longer Than Men
Summary: A new study reveals an increasing life expectancy gap between men and women in the United States, now at its widest since 1996. The study attributes this growing disparity…
