How To Find Simplicity In The Brain

Carnegie Mellon University Scientists can now monitor and record the activity of hundreds of neurons concurrently in the brain, and ongoing technology developments promise to increase this number manyfold. However, simply recording the neural activity does not automatically lead to a clearer understanding of how the brain works. In a new review paper published in Nature Neuroscience, Carnegie Mellon University's Byron M. Yu and Columbia University's John P. Cunningham describe the...

Brown University A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, Brown University neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle. In so doing, the...

Brandeis University A new model to understand neural self-regulation When your car needs a new spark plug, you take it to a shop where it sits, out of commission, until the repair is finished. But what if your car could replace its own spark plug while speeding down the Mass Pike? Of course, cars can't do that, but our nervous system does the equivalent, rebuilding itself continually while maintaining full function. Neurons live for many years but their components, the proteins...

Much-needed tool for neuroscience emerges after years of work Nearly a decade ago, the era of optogenetics was ushered in with the development of channelrhodopsins, light-activated ion channels that can, with the flick of a switch, instantaneously turn on neurons in which they are genetically expressed. What has lagged behind, however, is the ability to use light to inactivate neurons with an equal level of reliability and efficiency. Now, Howard Hughes Medical Institute (HHMI) scientists...

For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has...

TACOMA, Wash., Feb. 13, 2014 /PRNewswire/ -- Noted neuroscientist Dr. Rodolfo Llinas and colleagues have published an article reporting that Revalesio's RNS60 improves synaptic transmission. Synapses connect nerve cells and allow communication through the release of neurotransmitters, which are essential for normal function of the nervous system and overall brain activity. In their work, Dr. Llinas and his coworkers used the squid giant synapse, a well-established model for...

Team sees change in set point in neuromuscular synapses Scientists from the School of Medicine at The University of Texas Health Science Center at San Antonio have found a clue as to why muscles weaken with age. In a study published today in The Journal of Neuroscience, they report the first evidence that “set points” in the nervous system are not inalterably determined during development but instead can be reset with age. They observed a change in set point that resulted in...

Science paper by IST Austria scientists reports first evidence for “microdomain” coupling at a mature central synapse and explores the implications for synaptic plasticity In research published in this week’s online edition of Science (DOI: 10.1126/science.1244811), postdoc Nicholas Vyleta and Professor Peter Jonas of the Institute of Science and Technology Austria (IST Austria) uncover the existence of loose coupling between calcium channels and release sensors of exocytosis at a...

Neuroscientists Discover New ‘Mini-neural Computer’ In The Brain
2013-10-31 07:35:43

University of North Carolina at Chapel Hill School of Medicine Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at UNC have shown that dendrites actively process information, multiplying the brain’s computing power. The finding could help researchers better understand neurological disorders. Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now...

Dendrites In Brain Act As Mini-Neural Computers

Brett Smith for redOrbit.com - Your Universe Online Initially thought of as a simple means of sending signals in the brain, new research, published on Sunday in the journal Nature, has revealed that the dendrite sections of neurons are capable of processing information. "Suddenly, it's as if the processing power of the brain is much greater than we had originally thought," said study author Spencer Smith, an assistant professor in the UNC School of Medicine. "Imagine you're reverse...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
