Scientists regenerate neurons in mice with spinal cord injury and optic nerve damage
by
•Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research …read more Source:: Science
Device brings silicon computing power to brain research and prosthetics
by
•A new device enables researchers to observe hundreds of neurons in the brain in real-time. The system is based on modified silicon chips from cameras, but rather than taking a …read more Source:: Science
Scientists monitor brains replaying memories in real time
by
•In a study of epilepsy patients, researchers monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns …read more Source:: Science
Specific neurons that map memories now identified in the human brain
by
•Neuroengineers have found the first evidence that individual neurons in the human brain target specific memories during recall. They studied recordings in neurosurgical patients who had electrodes implanted in their …read more Source:: Science
Scientists stimulate neurons to induce particular perceptions in mice’s minds
by
•Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn’t so much why some people occasionally experience them. It’s why all of us aren’t …read more Source:: Science
A short bout of exercise enhances brain function
by
•Neuroscientists, working with mice, have discovered that a short burst of exercise directly boosts the function of a gene that increases connections between neurons in the hippocampus, the region of …read more Source:: Science
Small cluster of neurons is off-on switch for mouse songs
by
•Researchers have isolated a cluster of neurons in a mouse’s brain that are crucial to making the squeaky, ultrasonic ‘songs’ a male mouse produces when courting a potential mate. …read more Source:: Science
How old are your organs? To scientists’ surprise, organs are a mix of young and old cells
by
•Scientists once thought that neurons, or possibly heart cells, were the oldest cells in the body. Now, researchers have discovered that the mouse brain, liver and pancreas contain populations of …read more Source:: Science
These trippy images were designed by AI to super-stimulate monkey neurons
by
•To find out which sights specific neurons in monkeys ‘like’ best, researchers designed an algorithm, called XDREAM, that generated images that made neurons fire more than any natural images the …read more Source:: Science
