Turning on the switch for plasticity in the human brain

Scientists describe how glutamate signals are transmitted across synapses to turn on the switch for synapatic plasticity, the ability of synapses to strengthen or weaken over time in response to increases or decreases in their activity.

How the brain is programmed for computer programming?

Expert computer programmers show higher proficiency in certain behavioral and attention skills than their novice peers. To identify the responsible brain regions, scientists used fMRI to analyze the brain activities of 30 programmers of different skill…

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.

Scientists jump-start two people’s brains after coma

In 2016, a team reported that a 25-year-old man recovering from a coma had made remarkable progress following a treatment to jump-start his brain using ultrasound. Now, researchers report that two more patients with severe brain injuries have also made…

Brain activity during speaking varies between simple and complex grammatical forms

Some languages require less neural activity than others. But these are not necessarily the ones we would imagine. Researchers have shown that languages that are often considered ‘easy’ actually require an enormous amount of work from our brains.

Unlocking PTSD: New study reveals why trauma-focused psychotherapy treatment works

Trauma-focused psychotherapy is the best-known treatment for PTSD. But how does it work? A researcher may have found the answer by exploring how different parts of the brain talk to one another.

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.
