Can large fluid-filled spaces in the brain help identify those at risk of dementia?

People with enlarged fluid-filled spaces in the brain around small blood vessels may be more likely to develop cognitive problems and dementia over time than people without these enlarged spaces, according to a new study.

Malaria tricks the brain’s defense system

Malaria is one of the most common causes of death in children in Africa. When the parasite builds up in the blood vessels of the brain, it develops into one of the most dangerous forms of the disease, cerebral malaria. Though it wasn’t certain if the p…

Wirelessly rechargeable soft brain implant controls brain cells

Researchers have invented a smartphone-controlled soft brain implant that can be recharged wirelessly from outside the body. It enables long-term neural circuit manipulation without the need for periodic disruptive surgeries to replace the battery of t…

Newly discovered subset of brain cells fight inflammation with instructions from the gut

Astrocytes are the most abundant type of cells within the central nervous system (CNS), but they remain poorly characterized. Researchers have long assumed that astrocytes’ primary function is to provide nutrients and support for the brain’s more close…

Watching decision making in the brain

Neuroscientists and engineers have developed a system that can show the neural process of decision making in real time, including the mental process of flipping between options before expressing a final choice.

First observation of the early link between proteins linked to Alzheimer’s disease

Researchers demonstrate, for the first time in humans, how the first deposits of tau proteins in the brainstem are associated with neurophysiological processes specific to the early stages of Alzheimer’s disease development.

Stimulating brain pathways shows origins of human language and memory

Scientists have identified that the evolutionary development of human and primate brains may have been similar for communication and memory.

Fine tuning first-responder immune cells may reduce TBI damage

Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report. They also report for the first time …

PTSD link to pandemic fears

A new study of 1040 online participants from five western countries explores people’s response to the stresses of the escalating pandemic, finding more than 13 percent of the sample had post-traumatic stress disorder (PTSD) related symptoms consistent …

MRI helps unravel the mysteries of sleep

Scientists are investigating brain activity during sleep with the help of MRI scans. It turns out our brains are much more active than we thought.
