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...

MADISON "“ Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more -- and several hours of sleep will refresh it. Now new research from the University of Wisconsin School of Medicine and Public Health clarifies this phenomenon, supporting the idea that sleep plays a critical role in the brain's ability to change in response to its environment. This ability, called plasticity, is at the heart of learning. Reporting in the Jan....

By Anthony J. Brown, MD NEW YORK (Reuters Health) - When someone suffers a stroke, 1.9 million nerve cells in the brain die each minute, and the oxygen-starved brain ages about 3.6 years each hour -- further emphasizing the need for rapid treatment -- researchers say. "'Time is brain' is a popular saying: clinical outcomes have been shown to deteriorate the longer treatment is delayed," study author Dr. Jeffrey L. Saver, from the University of California in Los Angeles, told Reuters Health....

AUSTIN, Texas--Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory. The research, published online Oct. 23 and in the November issue of the journal Nature Neuroscience, shows that ion channels distributed in the dendritic membrane change during a simulated learning task and that this...

Botox, used by Hollywood stars to smooth out facial wrinkles, is playing an important role in UQ research to understand how nerve cells communicate with each other. The research is exploring basic nerve cell function, minute changes which underlie memory and learning, and possible causes of nerve diseases. Dr Frederic Meunier, a lecturer in UQ's School of Biomedical Sciences, is studying basic physiological processes at the molecular level. Dr Meunier is one of seven UQ finalists in the...

New Haven, Conn. - Inhibitory systems are essential for controlling the pattern of activity in the cortex, which has important implications for the mechanisms of cortical operation, according to a Yale School of Medicine study in Neuron. The findings demonstrate the inhibitory network is central to controlling not only the amplitude, extent and duration of activation of recurrent excitatory cortical networks, but also the precise timing of action potentials, and, thus, network...

NEW BRUNSWICK/PISCATAWAY, N.J. -- Rutgers' Bonnie Firestein likens nerve cells to trees -- some are short and bushy with many branches while others are tall with a few branches coming out of one or two main trunks. Different branching patterns correlate with specific disorders and Firestein's quest is to discover how these dissimilar patterns come about and why. A new paper by Firestein and her colleagues at Rutgers, The State University of New Jersey, examines the role of the protein snapin...

La Jolla, CA - Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In this week's journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other. The new study indicates that...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
