Differences in brain activity in children with anhedonia

Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy. The study sheds light on …

Parkinson’s treatment delivers a power-up to brain cell ‘batteries’

Scientists have gained clues into how a Parkinson’s disease treatment, called deep brain stimulation, helps tackle symptoms.

Gene that keeps PTSD-like behavior at bay in female mice

More than 30 years ago, scientists discovered that mad cow and Creutzfeldt-Jakob diseases are caused by prions. But in recent years, Nobel laureate Eric Kandel, M.D., demonstrated in mice that some prions are beneficial and serve important functions in…

Role of a deep brain structure in concussion

Through a combination of biometric tracking, simulated modeling and medical imaging, researchers detail how hits to the side of the head cause concussion.

Neurofeedback gets you back in the zone

Researchers have shown — for the first time — that they can use online neurofeedback to modify an individual’s arousal state to improve performance in a demanding sensory motor task, such as flying a plane or driving in suboptimal conditions.

First evidence for necessary role of human hippocampus in planning

A team of scientists reports finding the first evidence that the human hippocampus is necessary for future planning. The findings link its long-established role in memory with our ability to use our knowledge to map out the future effects of our actions.

Rsearchers explore stroke’s effects on microbiome

Researchers are investigating how having a stroke can disrupt the community of bacteria that lives in the gut. These bacteria — known collectively as the microbiome — can interact with the central nervous system and may influence stroke patients’ rec…

First double-blind controlled trial of TNS shows reduced symptoms in some children with ADHD

Currently approved in Canada and Europe for adults with medication-resistant depression and seizures, trigeminal nerve stimulation (TNS) has been found to be an effective and safe means of treatment for children with attention deficit hyperactivity dis…

Iron measurements with MRI reveal stroke’s impact on brain

A simple MRI method that measures iron content can provide a more comprehensive picture of the consequences of stroke-related damage to the brain, according to a new study. Researchers said the findings point to a role for MRI brain iron measurements i…

Dementia looks different in brains of Hispanics

A major new study has uncovered dramatic differences in the brains of Hispanics with a dementia diagnosis compared with those of non-Hispanic whites and of African Americans.
