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...

Understanding How Neurons Get Wired

University of Arizona Two different versions of the same signaling protein tell a nerve cell which end is which, UA researchers have discovered. The findings could help improve therapies for spinal injuries and neurodegenerative diseases. University of Arizona scientists have discovered an unknown mechanism that establishes polarity in developing nerve cells. Understanding how nerve cells make connections is an important step in developing cures for nerve damage resulting from spinal...

New approaches lead to intricate neural connectivity map Some optical illusions look like they're in motion even though the picture is static. A new map of the fly brain also suggests motion—or at least how the fly sees movement. The new research, published in the August 8 issue of Nature, takes advantage of a high-throughput approach that speeds the charting of neuronal connections involved in motion detection. Neurons snake through the brain, each reaching out and...

Breakthrough Could Lead to Better Understanding of Learning and Memory Students preparing for final exams might want to wait before pulling an all-night cram session – at least as far as their neurons are concerned. Carnegie Mellon University neuroscientists have discovered a new intermediate phase in neuronal development during which repeated exposure to a stimulus shrinks synapses. The findings are published in the May 8 issue of the Journal of Neuroscience. It's well known that...

A team of neuroscientists have proposed a new and potentially revolutionary way of determining the neuronal connectivity (the "connectome") of the whole brain of the mouse, in an essay published October 23 in the open access journal PLOS Biology. The team, led by Professor Anthony Zador, Ph.D. of Cold Spring Harbor Laboratory, aims to provide a comprehensive account of neural connectivity. At present the only method for obtaining this information with high precision relies on examining...
