Dodging Dots Helps To Explain Circuitry Of The Brain

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...

University of California - San Diego Researchers discover how neurons equalize between excitation and inhibition Researchers at the University of California, San Diego School of Medicine have discovered a fundamental mechanism by which the brain maintains its internal balance. The mechanism, described in the June 22 advanced online publication of the journal Nature, involves the brain's most basic inner wiring and the processes that control whether a neuron relays information to other...

NYU Langone Medical Center / New York University School of Medicine Findings should help narrow the search for genetic contributions of autism and suggest new routes for therapy "Aha" moments are rare in medical research, scientists say. As rare, they add, as finding mice with Mohawk-like hairstyles. But both events happened in a lab at NYU Langone Medical Center, months after an international team of neuroscientists bred hundreds of mice with a suspect genetic mutation tied to...

Leaps orders of magnitude beyond existing tools -- NIH study Scientists have bioengineered, in neurons cultured from rats, an enhancement to a cutting edge technology that provides instant control over brain circuit activity with a flash of light. The research funded by the National Institutes of Health adds the same level of control over turning neurons off that, until now, had been limited to turning them on. "What had been working through a weak pump can now work through a highly...

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...

redOrbit Staff & Wire Reports - Your Universe Online A drug given to pregnant mice with models of autism prevents autistic behavior in their offspring, according to a new study reported Friday in the journal Science. Although the drug could not be administered prenatally in humans since there is no way to screen for autism in human fetuses, clinical trials in which the drug was administered to young children who have already developed autistic symptoms are showing progress, the...

Inhibitory neuron type found to specifically suppress activation of other inhibitory neurons in cerebral cortex The cerebral cortex contains two major types of neurons: principal neurons that are excitatory and interneurons that are inhibitory, all interconnected within the same network. New research now reveals that one class of inhibitory neurons – called VIP interneurons -- specializes in inhibiting other inhibitory neurons in multiple regions of cortex, and does so under specific...

We've all heard the saying "you can't teach an old dog new tricks." Now neuroscientists are beginning to explain the science behind the adage. For years, neuroscientists have struggled to understand how the microcircuitry of the brain makes learning easier for the young, and more difficult for the old. New findings published in the journal Nature by Carnegie Mellon University, the University of California, Los Angeles and the University of California, Irvine show how one component of the...

They show how embryonic origin and timing influence cell specification and network integration The cerebral cortex of the human brain has been called "the crowning achievement of evolution." Ironically, it is so complex that even our greatest minds and most sophisticated science are only now beginning to understand how it organizes itself in early development, and how its many cell types function together as circuits. A major step toward this great goal in neuroscience has been taken by...

Researchers at Baylor College of Medicine and Texas Children's Hospital have identified commensal bacteria in the human intestine that produce a neurotransmitter that may play a role in preventing or treating inflammatory bowel diseases such as Crohn's disease. "We identified, to our knowledge, the first bifidobacterial strain, Bifidobacterium dentium, that is capable of secreting large amounts of gamma-aminobutyric acid (GABA). This molecule is a major inhibitory neurotransmitter in the...

New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder. Published online Thursday June 7, 2012 in the journal Neuron, researchers led by Benjamin D. Philpot, PhD, professor of cell and molecular physiology at UNC, describe how seizures in individuals with AS could be linked to an imbalance in the activity of specific...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
