Dementia study reveals how proteins interact to stop brain signals

Fresh insights into damaging proteins that build up in the brains of people with Alzheimer’s disease could aid the quest for treatments.

Brain function abnormal in children with Type 1 diabetes

Children with Type 1 diabetes show subtle but important differences in brain function compared with those who don’t have the disease, a study has shown.

Why doesn’t deep-brain stimulation work for everyone?

Researchers have mapped nine functional networks in the deep-brain structures of 10 healthy people, an accomplishment that could lead to improvements in deep-brain stimulation therapy for severe cases of Parkinson’s disease and other neurological condi…

Justified and unjustified movie violence evokes different brain responses

In a study, researchers find that scenes of justified and unjustified violence in movies activate different parts of the adolescent brain. The research is the first to show that when movie characters engage in violence that is seen as justified, there …

Brain patterns can predict speech of words and syllables

Neurons in the brain’s motor cortex previously thought of as active mainly during hand and arm movements also light up during speech in a way that is similar to patterns of brain activity linked to these movements, suggest new findings.

The genetic signature of memory

Despite their importance in memory, the human cortex and subcortex display a distinct collection of ‘gene signatures.’ The work increases our understanding of how the brain creates memories and identifies potential genes for further investigation.

How playing the drums changes the brain

People who play drums regularly for years differ from unmusical people in their brain structure and function. The results of a new study suggest that they have fewer, but thicker fibers in the main connecting tract between the two halves of the brain. …

Play sports for a healthier brain

There have been many headlines in recent years about the potentially negative impacts contact sports can have on athletes’ brains. But a new study shows that, in the absence of injury, athletes across a variety of sports — including football, soccer a…

Average IQ: What is it?

Intelligence quotient (IQ) is a score derived from standardized tests that measure a person’s cognitive ability against that of similarly aged peers. In this article, learn about the average IQ.

Scientists use crabs to validate popular method to identify unknown human brain neurons

A crab’s nervous system could help scientists learn what causes single neurons in the human brain to become ‘out of whack,’ which can contribute to the development of neurological diseases like Alzheimer’s disease. Knowing exactly how a single neuron o…
