April Flowers for redOrbit.com - Your Universe Online How our brains encode thoughts, such as perceptions and memories, at the cellular level is one of the biggest puzzles in neuroscience today. One theory suggests that ensembles of neurons represent each unique piece of information. No one knows, however, just what these ensembles look like, or how they form. A new study, published in a recent issue of Neuron, sheds light on how neural ensembles form thoughts and support the...

The brain's neurons are coupled together into vast and complex networks called circuits. Yet despite their complexity, these circuits are capable of displaying striking examples of collective behavior such as the phenomenon known as "neuronal avalanches," brief bursts of activity in a group of interconnected neurons that set off a cascade of increasing excitation. In a paper published in the American Institute of Physics' journal Chaos, an international team of researchers from China, Hong...

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 research that helps shed light on the malleability of this recognition process, Brown University neuroscientists have teased apart the potentially different roles that two distinct cell types may play. In a study published in the journal Neuron, the researchers document that this kind of learning is based in the inferior...

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. "Someday in the near future, quadriplegic patients will take advantage of this technology not only to move their arms and hands and to walk again, but also to sense the texture of objects placed in their hands, or...

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). "This research is the first time that precise time-keeping activities have been identified in recordings of neuron activity," Jin said. The time-keeping neurons are in two...

Populations of neurons code time with extreme precision in the primate brain What's new: MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. Why it matters: The timing of individual actions, whether we are speaking, driving a car, or playing...

One of the major scientific questions about the brain is how it can translate the simple intent to perform an action "” say, reach for a glass "” into the dynamic, coordinated symphony of muscle movements required for that action. The neural instructions for such actions originate in the brain'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 bird'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 body's movements.The study, reported in the...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
