“…Despite the large number of behavioral studies that have utilized static and dynamic perturbations to the articulators (e.g., Abbs and Gracco, 1984; Baum et al, 1996; Baum et al, 1997; Baum, 1999; Folkins and Abbs, 1975; Folkins and Zimmerman, 1982; Gay et al, 1981; Gomi et al, 2002; Gracco and Abbs, 1985; Jacks, 2008; Kelso et al, 1984; Lane et al, 2005; Lindblom et al, 1979; McFarland and Baum, 1995; Nasir and Ostry, 2006, 2008, 2009; Tremblay et al, 2003), few researchers have attempted to use non-invasive imaging techniques to investigate the neural substrates underlying the somatosensory feedback control of fluent speech production. Part of the challenge is that a device must be created that not only perturbs subjects’ articulator movements, but is also MR compatible.…”
