Ordinary skin cells morphed into functional brain cells

Scientists at CWRU School of Medicine discover new technique that holds promise for the treatment of multiple sclerosis and cerebral palsy.

 

Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.

 

This discovery appears today in the journal Nature Biotechnology ("Transcription factor–mediated reprogramming of fibroblasts to expandable, myelinogenic oligodendrocyte progenitor cells").This breakthrough now enables "on demand" production of myelinating cells, which provide a vital sheath of insulation that protects neurons and enables the delivery of brain impulses to the rest of the body.

 

In patients with multiple sclerosis (MS), cerebral palsy (CP), and rare genetic disorders called leukodystrophies, myelinating cells are destroyed and cannot be replaced.

Neural implants are set to be revolutionised by a new type of graphene transistor with a liquid gate, say bio-engineers
Gust MEES's insight:

Graphene is ideal because carbon “chicken wire” is only a single atom thick and therefore highly flexible. It is also held together by carbon bonds, which are among the most stable known to chemists. That means it should be relatively stable inside the human body.

Scientists model brain structure to help computers recognize objects

Scientists model brain structure to help computers recognize objects | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
(PhysOrg.com) -- An essential question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply 'looking' at an image. Introspectively, we know that the human brain solves this problem very well.

Brown University creates first wireless, implanted brain-computer interface

Brown University creates first wireless, implanted brain-computer interface | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

Brown’s wireless BCI, fashioned out of hermetically sealed titanium, looks a lot like a pacemaker. Inside there’s a li-ion battery, an inductive (wireless) charging loop, a chip that digitizes the signals from your brain, and an antenna for transmitting those neural spikes to a nearby computer.

 

The BCI is connected to a small chip with 100 electrodes protruding from it, which, in this study, was embedded in the somatosensory cortex or motor cortex.

 

These 100 electrodes produce a lot of data, which the BCI transmits at 24Mbps over the 3.2 and 3.8GHz bands to a receiver that is one meter away. The BCI’s battery takes two hours to charge via wireless inductive charging, and then has enough juice to last for six hours of use.

The aging brain is more malleable than previously believed

The aging brain is more malleable than previously believed | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
Neuroscientists are finding that, as we get older, our aging brains are proving surprisingly malleable, and in ways not previously anticipated. But there are limitations.
