The actifier: a device for neurophysiological studies of orofacial control in human infants.
A new device for the stimulation of intraoral tissues in human neonates is described. This instrument, known as an actifier, features a wide frequency range for mechanical stimulation, integrated multichannel electomyographic electrode pairs, and the capacity for transducing law compression during non-nutritive sucking behavior. The stimulus/recording interface consists of a modified pacifier. The actifier has been used to investigate the responsiveness of the sucking central pattern generator in human infants to mechanical perturbation.
