A microRNA controlling left/right neuronal asymmetry in Caenorhabditis elegans.

abstract：:Sensory systems can adapt to the conditions imposed on them. In the visual system, adapting to a pattern increases the threshold of the ability to see that pattern, and reduces the perceived contrast of the pattern above threshold. Most neurons of the striate cortex reduce their responsiveness after being stimulated f...
