Brain activity under anesthesia challenges what we know about consciousness

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listen…

Scientists discover ancient brain cells that help block distractions

Scientists have discovered a tiny group of neurons in an ancient brain region that acts like a built-in focus filter, helping the brain ignore distractions and zero in on what matters most. When researchers temporarily switched off these neurons in mic…

New brain study reveals speech learning works differently than we thought

A new study suggests that learning and remembering speech relies more on how the brain processes sounds and sensations than on the areas that control mouth and face movements. The discovery could reshape speech therapy and help improve future brain-bas…

Scientists discover neurons must break their DNA to build the brain

As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA…

Common plastic chemical linked to lifelong anxiety in new study

Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed sig…

Scientists found an early depression clue hidden in children’s eyes

Depression appears to change what children notice in the faces around them, but the effect depends on family history. Kids with a higher inherited risk became more focused on sadness, while lower-risk children lost some of their natural attention to ha…

Why middle age is becoming a breaking point in the U.S.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain…

Your brain can keep improving into your 90s, study finds

A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-t…
