Scientists discovered the brain doesn’t make decisions the way we thought

A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing in…

Scientists discover how the brain rewires itself to truly multitask

Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain’s “thinking” c…

Second pregnancy changes the brain in surprising new ways

Researchers found that every pregnancy rewires the brain in its own way, with a second pregnancy bringing a different pattern of changes than the first. The discoveries could lead to better ways to recognize and treat maternal mental health challenges,…

Scientists may have finally found how Alzheimer’s kills brain cells

Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer’s disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by interruptin…

Drinking to cope with stress may permanently rewire your brain

Using alcohol to cope with stress when young may permanently alter the brain, making it harder to adapt to challenges and increasing the risk of returning to drinking later in life. Researchers also found signs of brain damage associated with early dem…

A surprising brain discovery is forcing scientists to rethink movement disorders

A surprising discovery is overturning a long-held assumption about how the brain’s movement center works. Researchers found that two key cerebellar cell types—thought to be tightly linked—often don’t behave in predictable ways, even though one …

Scientists say creatine may help fight depression

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain’s energy supply. A new review examined five randomized clinical trials involving 238 particip…

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…
