Explaining Brain Circuitry By Dodging Dots
2014-07-09 03:49:18

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...

A tiny, translucent juvenile zebrafish, on the hunt for even littler prey, has offered up a big insight into how a specific circuit of nerve cells functions in the brain. The technique used to illuminate this circuitry, and the fish model itself, provide one of the first insights into the way individual sets of neurons control a specific behavior. The finding, reported in Science, (October 29, 2010), also illuminates the mastery of evolution, in the finely tuned mechanism the research...


Word of the Day
negawatt
  • A unit of saved energy.
Coined by Amory Lovins, chairman of the Rocky Mountain Institute as a contraction of negative watt on the model of similar compounds like megawatt.
