Calcium-based MRI sensor enables more sensitive brain imaging

Neuroscientists have developed an MRI sensor that lets them monitor neuron activity deep within the brain by tracking calcium ions. This type of sensing could allow researchers to link specific brain functions to their pattern of neuron activity, and t…

Keep calm and carry on: Scientists make first serotonin measurements in humans

Scientists have begun to unravel how serotonin acts, based on data collected in a first-of-its-kind experiment that utilized electrochemical probes implanted into the brain of awake human beings.

New models could uncover important answers for Alzheimer’s researchers

Alzheimer’s disease currently affects more than 5.5 million Americans and is one of the costliest diseases to treat, according to the Alzheimer’s Association. Characterized by a buildup of plaque in the brain, few animal models exist that researchers c…

Vitamin B-6 could help us to recall dreams

A new study suggests that taking a vitamin B-6 supplement before going to bed each night could help us to remember the details of our dreams.

Potential for more precise diagnosis and treatment of TBI

Patients who’ve suffered from traumatic brain injuries have changes in tiny blood vessels in their brains that researchers believe are linked to a range of cognitive symptoms. The findings may help doctors pinpoint specific types of TBIs and tailor per…

Chronic dizziness can result from, or trigger, psychiatric disorders

Dizziness can fall into a number of broad categories, including vertigo (spinning sensation), presyncope (near-fainting), and disequilibrium (imbalance). When a patient’s description of symptoms appears consistent with one of these categories, physicia…

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…
