Scientists have designed virtual human brain cells

FOX News

For centuries, scientists who have dedicated their lives to studying the human brain have attempted to unlock its mysteries. The role the brain plays in human personality -- as well as the myriad of disorders and conditions that come along with it -- is often difficult to study because studying the organ while it's still functioning in a human body is complicated. Now, researchers at The Allen Institute for Brain Science have introduced a new tool that could make such study a whole lot easier: functioning virtual brain cells. The fully 3D computer models of living human brain tissue are based on actual brain samples that were left over after surgery, and present what could be the most powerful testbed for studying the human brain ever created. The samples used to construct the virtual models was healthy tissue that was removed during brain operations, and represents parts of the brain that are typically associated with thoughts and consciousness, as well as memory.

Putting bigger brains down to our social nature is half-baked

New Scientist

In the past two million years, humans have experienced a massive increase in brain size, one not seen in any other species. This rapid evolution gave us brains roughly triple the volume of those of our pre-human ancestors. But the intelligence we enjoy as a result would seem to be advantageous for all sorts of species, not just us. So why was ours the only line to go down this route? The social brain hypothesis was a popular answer.

People with big brains have a different brain structure too

It turns out that in larger human brains, regions involved in bringing together information are hyperexpanded – but we don't know what affect this might have on intelligence yet. Armin Raznahan at the US National Institute of Mental Health in Maryland and his colleagues discovered this by comparing brain images from around 3,000 people. They compared the area of 80,000 points across the cortex – the large part of our brains that is involved in higher functions like thinking. Analysing these, they found that some particular areas expanded more than others in people who had an overall larger brain size. These regions seem to be involved in integrating information from across the brain, he says.

IBM Wants to Implant Fake Brains in Real Brains to Prevent Seizures


In Melbourne, Australia, Stefan Harrer is running an artificial software brain atop an artificial hardware brain in an effort to analyze a brain that isn't artificial at all. Ultimately, he and his colleagues envision merging these three brains together so that the artificial can augment the real.

2017 Could Be The Year When Brains Connect Without Our Mouths Speaking A Word

Another year begins, and another science fiction concept is becoming science fact. If that sounds incredible, consider that it's already happened in studies with rats and monkeys, and in a limited way with humans as well. None of the studies have quite accomplished mind reading, but they have bridged the chasm between brains in a way that didn't seem possible until now. The most notable non-invasive study involving humans, so far, showed that people sitting in different rooms can play a simple computer game together by using equipment that enables each person to "communicate" information via brain waves. It was a basic test of the theory, but it worked, and it demonstrates what's possible as the technology advances.
