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 AI-enhanced device worked reliably for seven months. The AI model adapts to natural shifts in brain activity, maintaining accuracy over...
Mapping Brain Cells Vulnerable to Alzheimer’s Protein Buildup
Summary: Researchers have identified memory-related brain cells that are highly vulnerable to tau protein accumulation, a key factor in Alzheimer’s disease. Using the MISS brain-mapping technique, they profiled 1.3 million cells in mice to pinpoint which cell types are most affected.Their findings show that glutamatergic neurons in the hippocampus are...
High-Fat Diet Triggers Memory Decline Within Times
Summary: A new study shows that just three days of a high-fat diet can cause memory impairments and brain inflammation in older adults, independent of obesity. Researchers compared young and old rats fed a diet with 60% of calories from fat and found that only the older rats showed cognitive...
People in the Minority Often Self-Silence, Affecting Their Behavior
Summary: A new study shows that people with minority viewpoints on controversial topics often self-silence when discussing their opinions, leading them to behave in ways that contradict their true beliefs. Researchers found that participants who disagreed with the majority view avoided fully expressing their stance and engaged in behaviors that...
Long-Term NSAID Use Has a Relation to Lower Dementia Hazard
Summary: A new study finds that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk of developing dementia. Researchers followed 11,745 adults over 14.5 years and found that those who used NSAIDs long-term had a 12% reduced dementia risk.However, short- and intermediate-term NSAID use did not...
