Modelling the brain with 'Lego bricks'

Modelling the brain with 'Lego bricks'
Researchers from the University of Luxembourg, in cooperation with the University of Strasbourg, have developed a computational method that could be used to guide surgeons during brain surgery. Surgeons often operate in the dark. They have a limited view of the surface of the organ, and can typically not see what lies hidden inside. Quality images can routinely be taken prior to the surgery, but as soon as the operation begins, the position of the surgeon’s target and risky areas he must avoid, continuously change.

Connectomics could map millions or billions of neurons

Connectomics could map millions or billions of neurons
Scientists working in connectomics, a research field occupied with the reconstruction of neuronal networks in the brain, are aiming at completely mapping of the millions or billions of neurons found in mammalian brains. In spite of impressive advances in electron microscopy, the key bottleneck for connectomics is the amount of human labor required for the data analysis.

How the brain inhibits individual muscle control

How the brain inhibits individual muscle control
The key to balance is, in part, the ability to overpower your mind. Your brain possesses what some researchers call “common drive.” It wants to activate and relax all muscles in synchrony, including the opposing ones. It’s probably why you find yourself swaying while trying to balance on one leg. When you start to teeter, your mind drives all the muscles to stiffen at the same time. The problem: This drive contains muscle oscillations, which cause you to sway again and continue the process.

Electrical brain stimulation improves people's creativity

Electrical brain stimulation improves people's creativity
Scientists have found a way to improve creativity through brain stimulation, according to researchers at Queen Mary University of London and Goldsmiths University of London. They achieved this by temporarily suppressing a key part of the frontal brain called the DLPFC, which is involved in most of our thinking and reasoning. The results, published in the journal Scientific Reports, show that participants who received the intervention showed an enhanced ability to 'think outside the box'.

Cracking the brain's memory codes

Cracking the brain's memory codes
In a pair of studies, scientists at the National Institutes of Health explored how the human brain stores and retrieves memories. One study suggests that the brain etches each memory into unique firing patterns of individual neurons. Meanwhile, the second study suggests that the brain replays memories faster than they are stored. The studies were led by Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH's National Institute of Neurological Disorders and Stroke (NINDS).

Stroke rehab device deduces intention directly from brain

Stroke rehab device deduces intention directly from brain
Stroke patients who learned to use their minds to open and close a device fitted over their paralysed hands gained some control over their hands, according to a new study from Washington University School of Medicine in St. Louis. By mentally controlling the device with the help of a brain-computer interface, participants trained the uninjured parts of their brains to take over functions previously performed by injured areas of the brain, the researchers said.

microRNAs could protect the brain from developing epilepsy

microRNAs could protect the brain from developing epilepsy
On December 16, 1997, hundreds of Japanese children were brought to hospital suffering from epilepsy-like seizures. They all had one thing in common: they had been watching an episode of the Pokemon TV show when their symptoms began. Doctors determined that their symptoms were triggered by five seconds of intensely bright flashing lights on the popular TV program. But why did the lights affect a few hundred children while thousands of other viewers were unharmed?

Blood-brain barrier model improves treatment of brain conditions

Blood-brain barrier model improves treatment of brain conditions
Delivering drugs to the brain is no easy task. The blood-brain barrier -a protective sheath of tissue that shields the brain from harmful chemicals and invaders - cannot be penetrated by most therapeutics that are injected into a person's blood stream. But for treating diseases of the central nervous system and cancers such as glioblastoma, it's essential to get drugs across this barrier and deliver them to where they are needed most.

Sentinel Cerebral Protection System receives FDA Clearance

Sentinel Cerebral Protection System receives FDA Clearance
Claret Medical has announced that it has received regulatory clearance from the U.S. Food and Drug Administration (FDA) for the Sentinel Cerebral Protection System (CPS), via de novo classification, enabling U.S. commercialisation of the device. The Sentinel is the first and only device available in the U.S. that offers protection against the risk of stroke by capturing and removing debris dislodged during transcatheter aortic valve replacement (TAVR) before it reaches the brain.

Combining MRI and optical microscopy improves brain research

Combining MRI and optical microscopy improves brain research
  Functional magnetic resonance imaging reveals changes in blood-oxygen levels in different parts of the brain, but the data show nothing about what is actually happening in and between brain cells, information needed to better understand brain circuitry and function.
