What happens in the brain during a ‘eureka!’ moment?

Neuroscientists recently studied that ‘Aha!’ moment you get when you finally solve a puzzle. It is linked to reward centers and our evolutionary history.

Music activates regions of the brain spared by Alzheimer’s disease

Researchers are looking to the salience network of the brain to develop music-based treatments to help alleviate anxiety in patients with dementia.

Predicting psychosis: Brain folds hold the key

Catching psychosis at an early stage is the key to successful treatment. Examining communication between folds on the cortex may predict those at risk.

New technology for measuring brain blood flow with light

Biomedical engineers have developed a new technique for measuring blood flow in the human brain, which could be used in patients with stroke or traumatic brain injury, for example. The new technique, based on conventional digital camera technology, cou…

What are delusions of grandeur?

Depression: Pioneering study pinpoints 44 genetic culprits

The authors of a large-scale new genome study have identified dozens of new genetic variants that can heighten the risk of major depression.

Loss of brain synchrony may explain working memory limits, says study

A new study may have revealed the reasons behind our memory limitations. The researchers found that trying to retain too much information in our working memory leads to a communication breakdown between parts of the brain responsible for maintaining it.

Noninvasive brain tumor biopsy on the horizon

Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers is developing a way that allows them to detect tumor biomarkers through a simple blood test.
