A canonical neural mechanism for behavioral variability
Nature Communications, Published online: 22 May 2017; doi:10.1038/ncomms15415
Irregular neuronal activity is thought to underlie motor variability. Here the authors use a combination of modelling, neuronal recordings in singing birds and analysis of babbling vocalizations, including of human infants, to show that topographically organized inputs to a widely recurrent motor network self-organize to generate variable motor output.
