Higher levels of leptin indicate brain protection against late-life dementia
A study more closely links obesity to dementia, finding that leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults.
A new target for anxiety disorders
By generating mice with genetic mutations that disrupt the brain's TrkC-PTP protein complex, researchers find a key way that brain cells communicate.
To sound like a hockey player, speak like a Canadian
Hockey players are famous for their distinctive jargon, but while researching this phenomenon, a linguist and hockey player realized another interesting pattern in hockey speech: American hockey players adopted aspects of Canadian English pronunciations. Their pseudo-Canadian accent might be a mechanism for the Americans to indicate their identity as hockey players in a sport heavily dominated by Canadians.
Echoes in the brain: Why today's workout could fuel next week's bright idea
In a pioneering longitudinal study, researchers found that the everyday effects of sleep, exercise, heart rate and mood -- both good and bad -- could linger in our brains for over two weeks.
Huntington's disease gene also enhances early brain development and intelligence, study finds
The Huntington's disease (HD) mutation eventually causes a fatal brain disease in adulthood, but a new study finds that early in life, children with the HD mutation have bigger brains and higher IQ than children without the mutation.
Can everyday physical activity improve cognitive health in middle age?
Engaging in everyday physical activity has immediate benefits for brain health. Middle-aged people who participated in everyday movement showed improvement in cognitive processing speed equivalent to being four years younger, regardless of the activity's intensity.
Brain recordings in people before surgery reveal how all minds plan what to say prior to speaking
A new study in people undergoing surgery to treat seizures related to epilepsy shows that pauses in speech reveal information about how people's brains plan and produce speech.
Combining VR and non-invasive brain stimulation: A neurotechnology that boosts spatial memory without surgery
Researchers have joined forces to give a boost to spatial memory by creating a unique experimental setup that combines non-invasive deep-brain stimulation, virtual reality training, and fMRI imaging. The study demonstrates that targeted, painless electric impulses to the hippocampus and adjacent structures, a deep brain region implied in memory and spatial navigation, can improve the brain's ability to recall locations and navigate more effectively.
Similarities in brain development between marmosets and humans
In common marmosets, the brain regions that process social interactions develop very slowly, extending until early adulthood, like in humans. During this time, all group members are involved in raising the infants, which contributes to the species' strong socio-cognitive skills.
Can a computer tell patients how their multiple sclerosis will progress?
Machine learning models can reliably inform clinicians about the disability progression of multiple sclerosis, according to a new study published this week in the open-access journal PLOS Digital Health by Edward De Brouwer of KU Leuven, Belgium, and colleagues.
