Modulation of Motor and Premotor Activity during Imitation of Target-directed Actions

Abstract: Behavioral studies reveal that imitation performance and the motor system are strongly influenced by the goal of the action to be performed. We used functional magnetic resonance imaging (fMRI) to assess the effect of explicit action goals on neural activity during imitation. Subjects imitated index finger movements in the absence and presence of visible goals (red dots that were reached for by the finger movement). Finger movements were either ipsilateral or contralateral. The pars opercularis of the inferior… Show more

“…These neurons represent actions in the same way when they are observed or self-produced, and are thus an ideal candidate for explaining the link between perception and action in imitation. Brain areas with mirror properties have also been discovered in the human parietal and premotor cortices (e.g., Grèzes et al 2003;Iacoboni et al 1999;Koski et al 2002;Leslie et al 2004). Consistent with the present findings of body part specific mirroring effects, these brain structures are somatotopically organized and represent foot and hand actions in anatomically distinct areas (Buccino et al 2001).…”

“…Imaging studies have confirmed that a similar system is also present in humans (e.g. Grèzes et al 2003;Buccino et al 2001;Iacoboni et al 1999;Koski et al 2002), and this system has been linked to the automatic imitation of actions by imaging and behavioral studies (e.g., Jackson et al 2006;Leslie et al 2004;Wohlschläger and Bekkering 2002).…”

“…Given the time-course of the blood oxygen level-dependent (BOLD) fMRI response, which takes several seconds to return to baseline (34), contiguous brain volumes cannot be considered independent observations (35,36). Thus, the sum of signal intensity at each voxel throughout each task was used as the dependent variable (12,13,22). Significance level was set at P ϭ 0.001 uncorrected at each voxel.…”

“…(iii) The inferior frontal cortex codes the goal of the action [both neurophysiological (5,20,21) and imaging data (22) support this role for inferior frontal mirror neurons]. (iv) Efferent copies of motor plans are sent from parietal and frontal mirror areas back to the superior temporal cortex (12), such that a matching mechanism between the visual description of the observed action and the predicted sensory consequences of the planned imitative action can occur.…”

“…At the observation stage, activation was observed in the middle frontal gyrus (BA6 and BA46), inferior frontal gyrus (BA9), precentral gyrus (BA4), inferior parietal lobule (BA40), cuneus, and bilateral middle occipital gyrus (BA18). For the imitation stage, there was a significant activation in brain areas known to be activated during hand motor imitation (Gatti et al., 2017; Koski et al., 2002; Leslie, Johnson‐Frey, & Grafton, 2004), such as the precentral gyrus (BA6 and BA44), postcentral gyrus (BA3), inferior parietal lobe (BA40), and medial frontal gyrus (BA6). Overall, action observation activated more vision‐related brain areas (occipital lobe), while action imitation activated more premotor areas (i.e., precentral gyrus and postcentral gyrus).…”
