Latest Neural ensemble Stories
How our brains encode thoughts, such as perceptions and memories, at the cellular level is one of the biggest puzzles in neuroscience today.
The brain's neurons are coupled together into vast and complex networks called circuits.
No matter what novel objects we come to behold, our brains effortlessly take us from an initial "What's that?" to "Oh, that old thing" after a few casual encounters.
In a first ever demonstration of a two-way interaction between a primate brain and a virtual body, two monkeys trained at the Duke University Center for Neuroengineering learned to employ brain activity alone to move an avatar hand and identify the texture of virtual objects.
Groups of neurons that precisely keep time have been discovered in the primate brain by a team of researchers that includes Dezhe Jin, assistant professor of physics at Penn State University and two neuroscientists from the RIKEN Brain Science Institute in Japan and the Massachusetts Institute of Technology (MIT).
Populations of neurons code time with extreme precision in the primate brain.
One of the major scientific questions about the brain is how it can translate the simple intent to perform an action â€” say, reach for a glass â€” into the dynamic, coordinated symphony of muscle movements required for that action. The neural instructions for such actions originate in the brainâ€™s primary motor cortex, and the puzzle has been whether the neurons in this region encode the details of individual muscle activities or the high-level commands that govern kinetics...
When the eye tracks a birdâ€™s flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists. Now, University of California, San Francisco (UCSF) researchers have broken ground in understanding how the brain generates this tracking motion, a finding that offers a window, they say, into how neurons orchestrate all of the bodyâ€™s movements.
