How the Brain Processes Speech in Real Time

Summary: Researchers have developed a computational framework that maps how the brain processes speech during real-world conversations. Using electrocorticography (ECoG) and AI speech models, the study analyzed over 100 hours of brain activity, revealing how different regions handle sounds, speech patterns, and word meanings.The findings show that the brain processes...

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...

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...

How Head Action Is Reported by Eye Size When Sleeping With Eye Open

Summary: A new study reveals that pupil size fluctuates constantly during sleep, reflecting changes in brain activation levels. Researchers developed a novel method to keep test subjects’ eyes open, allowing them to monitor these dynamics without disrupting sleep.They found that pupil changes correspond to sleep stages, brain waves, and responsiveness...

More About Human Thoughts Could Be Discovered Through Psychological” Noise” Than Expected

Summary: New studies challenge the idea that variability in human behavior, often seen as “noise,” is simply an error to be minimized. Researchers argue that noise provides valuable insights into cognitive processes, from decision-making to moral reasoning.By applying computational models, they show how different types of noise can reflect distinct...
