Neuroscientists at University of California have identified 'anxiety cells' in the brain’s hippocampus. The finding, so far demonstrated with mice, could lead to better treatments for anxiety disorders in humans because the cells probably exist in humans, too, researchers say.
Neuroscientists at the University of California, Berkeley have claimed to track a thought racing across the brain. The finding confirms how the prefrontal cortex coordinates complex interactions between different regions in the brain - to help us act in response to what we perceive.
Scientists have used magnetic nanoparticles to directly control physical movements of mice. Using a technique called Magneto-Thermal Stimulation, researchers activate sections of the brain that cause mice to run, rotate or lose control of the extremities.
Scientists have created perfect replicas of human faces that were shown to monkeys just from recording the animal’s brain signals. This has solved one of the most intractable problems in neuroscience – "how the brain recognizes faces."
Chronic sleep deprivation can cause the brain to start eating itself, according to study at the Marche Polytechnic University in Italy. Astrocytes are cells in our brain that destroy and digest worn-out cells and debris, but researchers studying the brain of mice have found that these cells go into overdrive when the animals are chronically sleep-deprived, destroying more of the brain's neural connections.
Locked-in syndrome patients can now have simple conversations using a non-invasive brain-computer interface system. It was generally believed that completely locked-in patients were unable to communicate with the outside world, but this groundbreaking technology allows researchers to decode the paralyzed patients thought , thus making the communication possible.
Researchers at the University of North Carolina at Chapel Hill have developed a method which uses light to control protein activity inside live cells with the flick of a switch. According to the researchers, the technique, developed in the early 2000s, uses light to activate and deactivate proteins that could turn brain cells on and off.
Scientists at the University of Cambridge have found a way to remove specific fears from the brain. Unlike the traditional method in which the patients have to undergo some form of aversion therapy, this new method uses a combination of artificial intelligence and brain scanning technology to unconsciously remove a fear memory from the brain.
Neuroscientist Matt Wall talks about neuroimaging in a recent TEDxVienna talks - What If We Could Really Read The Brain?
