Perceived intensity of somatosensory cortical electrical stimulation.

abstract：:Experimental behavioral data show that written action descriptions are remembered better when encoded by enacting them compared with merely verbal encoding. To explore this facilitating effect of encoding by performing actions ('enactment effect'), a functional magnetic resonance imaging (fMRI) study was conducted wit...
