The technology I want to talk about today is something out of this world, but also a bit controversial There is a startup in Australia who are actually growing live human neurons and then integrating it into traditional computer chips
 mind-blowing stuff!

Growing brains can be a tricky process, but growing ones that can make muscles move? That’s an incredible feat. Here’s how scientists did it.

Cerebral organoids at the air-liquid interface generate nerve tracts with functional output.

“The capacity for this model to be used to investigate the way in which neurons connect up within the brain and with the spinal cord could have important implications for our understanding of a range of diseases. In particular defects in neuronal connectivity are thought to underlie various psychiatric illnesses, including schizophrenia, autism, and depression. ”

“Finally, through electrophysiological and co-culture studies, we demonstrate functionality of these tracts, which are even capable of eliciting coordinated muscle contractions in co-cultured mouse spinal cord–muscle explants. This approach is likely to be a useful new tool, not only because of its ease, but also due to its util-ity in studying axon guidance, tract formation, and connectivity in a human system”

“The stuff we really care about in the brain, like consciousness, are emergent phenomena—they arise from the collective workings of individual neurons, which create a whole that’s greater than the sum of its parts. The problem is that we don’t know at what level these phenomena emerge. A neuron is not conscious. A person is. What about all the steps in the middle? What about 2 million neurons? 20 million? 200 million?”

Researchers at Texas A&M University have developed the first molecular therapeutic for Angelman syndrome to advance into clinical development.

In a new article, published today in Science Translational Medicine, Dr. Scott Dindot, an associate professor and EDGES Fellow in the Texas A&M School of Veterinary Medicine and Biomedical Sciences’ (VMBS) Department of Veterinary Pathobiology, and his team share the process through which they developed this novel therapeutic candidate, also known as 4.4.PS.L, or GTX-102. Dindot is also the executive director of molecular genetics at Ultragenyx, which is leading the development of GTX-102.

Angelman syndrome (AS) is a devastating, rare neurogenetic disorder that affects approximately 1 in 15,000 per year; the disorder is triggered by a loss of function of the maternal UBE3A gene in the brain, causing , absent speech, movement or balance disorder, and seizures.

Changes in the brain caused by Alzheimer’s disease are associated with shortening of the telomeres—the protective caps on the ends of chromosomes that shorten as cells age—according to a new study led by Anya Topiwala of Oxford Population Health, part of the University of Oxford, UK, published March 22 in the open-access journal PLOS ONE.

Telomeres on chromosomes protect DNA from degrading, but every time a cell divides, the telomeres lose some of their length. Short telomeres are a sign of stress and cellular aging, and are also associated with a higher risk of neurological and psychiatric disorders. Currently, little is known about the links between and changes that occur in the brains of people with neurological conditions. Understanding those relationships could offer insights into the biological mechanisms that cause neurodegenerative disorders.

In the new study, researchers compared telomere length in to results from brain MRIs and from more than 31,000 participants in the UK Biobank, a large-scale biomedical database and research resource containing anonymized genetic, lifestyle and from half a million UK participants.

“This interface could revolutionize the way we interact with technology.”

Researchers from the University of Cambridge have created a new type of neural implant that could restore limb function in paralyzed limbs.

There have been former attempts at using neural implants to restore limb function, but these mostly failed. This is because scar tissue can envelop the electrodes over time, disrupting the connection between the device and the nerve.

The developed device works in sync between the brain and paralyzed limbs — it combines flexible electronics and human stem cells to “better integrate” with the nerve and drive limb function, according to a press release.
