Selenium Protects a Specific Type of Interneurons in the Brain

Scientific ‘by-catch‘ solves decades-old mystery

03-Jan-2018

200 years after the discovery of the trace element selenium, researchers at Helmholtz Zentrum München have shown for the first time why this chemical element is indispensable for mammalian life. As integral part of the enzyme GPX4, selenium protects a subset of neurons from cell death during ...

Smart people have better connected brains

24-Nov-2017

Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people’s brains also wired differently to those of less intelligent persons? A new study published by researchers from Goethe University Frankfurt (Germany) supports this ...

Circular RNA linked to brain function

16-Aug-2017

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders. While hundreds ...

Modeling the brain with 'Lego bricks'

19-Jun-2017

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 ...

Understanding the architecture of our 'second brain'

22-May-2017

Scientists have made an important step in understanding the organisation of nerve cells embedded within the gut that control its function -- a discovery that could give insight into the origin of common gastrointestinal diseases, including irritable bowel syndrome and chronic constipation. The ...

The veins in your brain don't all act the same

11-May-2017

Certain blood vessels in the brainstem constrict when blood vessels elsewhere in the body would dilate. And that contrary behavior is what keeps us breathing, according to a new paper by UConn researchers. If the body were a marching band, the brainstem would be the drum major. It keeps our heart ...

No sugar coating, but sweet nonetheless

First long-term stabile brain implant developed based on an anti-inflammatory coating

07-Apr-2017

Complex neurotechnological devices are required to directly select and influence brain waves inside the skull’s interior. Although it has become relatively easy to implement the devices, researchers are still faced with challenges when trying to keep them running properly in living organisms over ...

New, ultra-flexible probes form reliable, scar-free integration with the brain

17-Feb-2017

Engineering researchers at The University of Texas at Austin have designed ultra-flexible, nanoelectronic thread (NET) brain probes that can achieve more reliable long-term neural recording than existing probes and don't elicit scar formation when implanted. A team led by Chong Xie, an assistant ...

Switching specific G-protein-coupled signalling pathways on and off

12-Apr-2016

Blue on, yellow off: using different-coloured light, researchers are able to switch signalling pathways in the brain on and off. Researchers in Bochum have utilised light-sensitive proteins from nerve cells of the eye – so-called melanopsins – to switch on specific signalling pathways in brain ...

The brain starts to give up its secrets

Scientists unveil a key mechanism that could improve brain function

19-Feb-2016

A research team, led by the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal, has broken new ground in our understanding of the complex functioning of the brain. The research, which is published in the current issue of the journal Science, demonstrates that brain ...
