Scientists have identified a protective brain pathway that may help slow the progression of Parkinson's disease by strengthening the brain's own dopamine‑producing neurons, but the positive effect was ...

In recent years, scientists have identified hundreds of different genes associated with autism, a burst of discovery that has ...

Alzheimer's disease not only robs people of their memory but also affects mood, often causing anxiety and depression. Until now, scientists haven't fully understood how these symptoms are connected in ...

Scientists have known for some time that Alzheimer’s disease affects brain regions differently. And they have a detailed understanding of how misfolded tau forms toxic tangles in the brain, impairing ...

Scientists have long known that stress and addiction travel together, but the biological connection between a hard day and a hard-to-break habit has been far less clear. New research now identifies a ...

The Importance of Gliotransmitters for Brain Function, Plus Cognitive and Motor Efficiencies Gliotransmitters are neurochemicals released by glial cells. They support communication between neurons and ...

New research suggests pregnancy doesn’t impair the brain—it reshapes it, refining memory, attention, and emotional awareness ...

New peer-reviewed research from University College Cork traces how voluntary exercise reshapes tryptophan metabolism through the gut microbiota, lowering a key receptor in the memory center of the ...

The 1950s were a relatively rudimentary era for experimental neurophysiology. Recording the electrical activity of neurons wasn’t uncommon, but the methods often demanded considerable patience and ...

In a recent study published in the journal Science Advances, researchers tested whether low, clinically relevant doses of metformin lower blood glucose via inhibition of Ras-related protein 1 (Rap1) ...
