More than a feeling: sensation from cortical stimulation

Nat Neurosci. 2008 Jan;11(1):10-1. doi: 10.1038/nn0108-10.


Changes in neuronal firing underlie sensation, but how many neurons are needed to perceive these activity shifts? Two new studies in Nature suggest that the experimental modulation of only a few neurons can influence perception.
