Neuroscientists Discover New ‘Mini-neural Computer’ In The Brain

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...

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...

Neuroscientists at MIT's Picower Institute of Learning and Memory have uncovered why relatively minor details of an episode are sometimes inexplicably linked to long-term memories. The work is slated to appear in the Jan. 13 issue of Neuron. "Our finding explains, at least partially, why seemingly irrelevant information like the color of the shirt of an important person is remembered as vividly as more significant information such as the person's impressive remark when you recall an episode...

Dendrites integrate thousands of inputs locally before sending signals to central axon A tiny neuron is a very complicated structure. Its complex network of dendrites, axons and synapses is constantly dealing with information, deciding whether or not to send a nerve impulse, to drive a certain action. It turns out that neurons, at one level, operate like another complicated structure -- the United States, particularly its system of electing a president, through the Electoral College. A new...

U.S. scientists say a new study of neurons supports one of several competing models that attempt to explain how neurons integrate synaptic inputs. Northwestern University researchers in Evanston, Ill., say a neuron is a very complex structure, with dendrites integrating thousands of inputs before it sends a signal to a central axon. Synapses constantly deal with information, deciding whether to send a nerve impulse to drive a certain action. The Northwestern scientists say their study...

Proteins go everywhere in the cell and do all sorts of work, but a fundamental question has eluded biologists: How do the proteins know where to go? "There's no little man sitting there, putting the protein in the right place," said Don Arnold, a molecular and computational biologist at USC College. "Proteins have to have in them encoded information that tells them where to go in the cell." In a study appearing online this week in Nature Neuroscience, Arnold and collaborators solve the...

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...


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.
