Discovering the molecule that drove her madness.

Cannabis has been used by humans for thousands of years and is one of the most popular drugs today. With effects such as feelings of joy and relaxation, it is also legal to prescribe or take in several countries.

Researchers from a USC-led consortium have discovered 15 “hot spots” in the genome that either speed up brain aging or slow it down — a finding that could provide new drug targets to resist developmental delays, Alzheimer’s disease and other degenerative brain disorders.

Typically, people who experience psychosis encounter it in young adulthood or alongside dementia later in life. Post-COVID psychosis can hit adults in their middle years.

Research published in the journal Depression & Anxiety provides evidence that neurocognitive abnormalities are related to difficulties in social connection among people with posttraumatic stress disorder. The findings suggest that those with PTSD are more likely to struggle with managing multiple pieces of social information.

The accidental finding was made when a man suddenly died during a routine brain scan.

Insurance for your mind.

The human brain gobbles up to 10 times more energy than the rest of the body, eating through 20 percent of our fuel intake on average when we're resting.

Sleep is a vital function that allows your mind and body to recharge and remain refreshed and alert during the day. Quality sleep keeps your body healthy and strong enough to fend off diseases. Without adequate sleep, your brain may fail to function appropriately, impairing your ability to process memories, concentrate, and think clearly.

Scientists in Israel say they have observed exactly how the brain can make the body sick — and believe tweaks in the behavior of gray matter could stop inflammation in the bowel, colon and elsewhere.

For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments.

In the study, almost 80% of patients with treatment-resistant depression experienced remission after receiving modified transcranial magnetic stimulation.

Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution. We find that hominin brains experienced positive rate changes at 2.1 and 1.5 million years ago, coincident with the early evolution of Homo and technological innovations evident in the archeological record. But we also find that human brain size reduction was surprisingly...

It’s the first study of individualized brain stimulation to treat severe depression. Sarah’s case raises the possibility the method may help people who don’t respond to other therapies.

Everybody knows sleep is important, but there's still a lot we don't understand about what it actually does to the brain – and how its benefits could be boosted.

Recent research in mice turned to the blood-brain barrier for clues as to why Alzheimer's disease occurs and how to stop it.

A spectroscopic liquid biopsy technique can detect both small and low-grade brain tumours

Using a brain-computer interface, a clinical trial participant was able to create text on a computer at a rate of 90 characters per minute just by thinking about the movements involved in writing by hand.

There’s growing evidence that signals sent from our internal organs to the brain play a major role in regulating emotions and fending off anxiety and depression

Waking reality and dreams are different versions of the same thing.
