Moderate drinking linked to brain changes and cognitive decline

Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a p…

Sentences have their own timing in the brain

Our brain links incoming speech sounds to knowledge of grammar, which is abstract in nature. But how does the brain encode abstract sentence structure? In a neuroimaging study, researchers report that the brain encodes the structure of sentences (‘the …

Could eating fruit more often keep depression at bay?

A study surveyed 428 adults and looked at the relationship between their consumption of fruit, vegetables, sweet and savoury food snacks and their psychological health. The more often people ate fruit, the lower they scored for depression and the highe…

A brain network for social attraction

How does an animal’s brain recognize other animals of its own kind? Scientists studying this process in young zebrafish have now discovered a neuronal circuit that mediates social attraction. This specialized pathway, which runs from the retina deep in…

Hidden consciousness detected with EEG predicts recovery of unresponsive patients

Using EEG to identify covert consciousness in unresponsive brain-injured patients could help predict which ones may recover, researchers have found.

Scientists pinpoint reason why women may not respond to depression treatments the same as men

Previous analyses within the nucleus accumbens showed that different genes were turned on or off in women, but not in men diagnosed with depression. These changes could have caused symptoms of depression, or alternatively, the experience of being depre…

Whether you’re 18 or 80, lifestyle may be more important than age in determining dementia risk, study reveals

Individuals with no dementia risk factors, such as smoking, diabetes or hearing loss, have similar brain health as people who are 10 to 20 years younger than them, according to a new study. The study found that a single dementia risk factor could reduc…

New study reveals where memory fragments are stored

While the overall experience is stored in the hippocampus, the brain structure long considered the seat of memory, individual details are parsed and stored elsewhere, in the prefrontal cortex. This separation ensures that, in the future, exposure to an…

Experience required: A role for vision in the development of inhibitory networks

New research demonstrates that inhibitory and excitatory neuronal circuits of the visual system develop through different processes, even if the organization of the mature circuit is similar. These findings highlight the importance of the continued stu…

New research provides insight into Long COVID and ME

Researchers have uncovered how post-viral fatigue syndromes, including Long COVID, become life-changing diseases and why patients suffer frequent relapses.
