Brain

Binge-drinking in early adult years fundamentally changes how brain neurons communicate, in what scientists equate to a faulty gas pedal in a car that needs more pressure applied to "go." This type of dysfunction is also seen in Alzheimer's disease.

Researchers have developed an AI model that can spot bits of brain tumors that surgeons may miss while removing them from patients. It can detect these remaining tissues in as little as 10 seconds, and help prevent post-procedure complications.

Fascinating new findings uncover how clusters of 'brain stars' retain our learnings – and it changes what we previously understood about how memories are held and retrieved in our minds. The medical implications of this are vast.

Spanning nearly 100 laboratories in 45 countries, a landmark study has, for the first time, shown an association between genetic brain shape and size and the prevalence of neurological conditions such as Parkinson's disease and ADHD.

A laser-led device that shoots light into the brain to test blood flow and volume can offer instant feedback on a patient's stroke risk and and provide a portable, affordable and non-invasive way for clinicians to make life-saving interventions.

An innovative start-up is out to change how attention-deficit/hyperactivity disorder is managed, with non-invasive light electrical brain stimulation delivered by a headband worn for just 20 minutes a day that aims to improve poor executive function.

Synchron has announced that a trial participant has used its brain-computer interface to turn on the lights in his home, see who is at the door, and choose what to watch on the TV – hands-free and without even a voice command.

Researchers have discovered a fascinating new link between the gut and the brain: swallowing nutritious food causes the release of the feel-good chemical serotonin. The findings open the door to developing new treatments for eating disorders.

Whether we've watched athletes do it or experienced it ourselves, 'choking' in a high-stakes moment comes down to more than composure. For the first time, scientists have uncovered a set of neurons that fail to do their job when the payoff is greatest.

A new study has somewhat redeemed the tau protein, which up to now has been associated with the development of Alzheimer’s disease. Turns out, the protein has a ‘good guy’ role, helping to protect against harmful free radicals in the brain.

Like a computer system with built-in redundancies, a study has revealed that brains use three different sets of neurons to store a single memory. The finding could one day help soften painful memories in people who've suffered trauma.

A severe brain injury can leave patients unresponsive to stimuli, but they may be more aware than we realize. A new study of brain activity has shown that up to a quarter of unresponsive patients may exhibit “hidden consciousness.”
