Fatty food before surgery may impair memory in old, young adults

Eating fatty food in the days leading up to surgery may prompt a heightened inflammatory response in the brain that interferes for weeks with memory-related cognitive function in older adults — and, new research in animals suggests, even in young adults.

Abnormal brain structure identified in children with developmental language problems

A rigorous analysis of numerous studies concludes that a part of the brain traditionally associated with movement is abnormal in children with developmental language impairments. The discovery has the potential to improve both the diagnosis and treatme…

New study reveals breakthrough in understanding brain stimulation therapies

Researchers show that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.

How fear unfolds inside our brains

The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats — such as in PTSD — have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circ…

Blast-related concussions linked to higher Alzheimer’s risk

U.S. veterans of the wars in Afghanistan and Iraq who suffered mild traumatic brain injury from exposure to explosive blasts were found to have changes in cerebrospinal fluid proteins that are typically seen in people who develop Alzheimer’s disease, a…

Interactions with dogs can increase brainwaves associated with stress relief and heightened concentration

Spending quality time with dogs reduces stress and increases the power of brain waves associated with relaxation and concentration, according to a new study.

Researchers identify brain connections associated with ADHD in youth

Researchers have discovered that symptoms of attention-deficit/hyperactivity disorder (ADHD) are tied to atypical interactions between the brain’s frontal cortex and information processing centers deep in the brain. The researchers examined more than 1…

Researchers expand our understanding of how the body and brain communicate

Researchers investigating how exactly the brain processes the incoming stream of information from the heart and lungs, discovered that specific neurons in the thalamus are actively involved in processing cardiac and respiratory signals.

For people who speak many languages, there’s something special about their native tongue

A study of polyglots found the brain’s language network responds more strongly when hearing languages a speaker is more proficient in — and much more weakly to the speaker’s native language.

Happiness can be learnt, but you have to work at it

We can learn to be happy, but only get lasting benefits if we keep practicing, a new study has revealed.
