Sleeping nine hours or more per night is associated with worse cognitive performance, and it is even more the case for those with depression.

A research team has demonstrated how the energy levels of individual neurons in the brain change during so-called spreading depolarizations — waves of activity that occur in various brain disorders. The findings provide important foundations for under…

That ‘aha’ moment when you come back to a puzzle and immediately figure it out? Something fascinating is going on in your brain. A new study using functional magnetic resonance imaging shows that these flashes of insight aren’t just satisfying — they …

A pioneering research study details how the hormone FGF21 (fibroblast growth factor 21) can reverse the effects of fatty liver disease in mice. The hormone works primarily by signaling the brain to improve liver function.

A transient ischemic attack, also known as a mini-stroke, is typically defined as a temporary blockage of blood flow to the brain that causes symptoms that go away within a day, but a new study finds that people who have this type of stroke may also ha…

Researchers identified two brain networks involved in word retrieval — the cognitive process of accessing words we need to speak. A semantic network processes meaning in middle/inferior frontal gyri, while an articulatory network in inferior frontal/p…

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior of our neurons and cognitive processes. Recently, re…

A new study finds that an easily measurable brain wave shift of phase may be a universal marker of unconsciousness under general anesthesia.
