Scientific evidence points to a shared neural representation between performing and observing an action. The action observation notoriously determines a modulation of the observer’s sensorimotor system, a phenomenon called Motor Resonance (MR). Fibromyalgia (FM) patients suffer from a condition characterized by generalized musculoskeletal pain in which even simple movement can exacerbate their symptoms. Maladaptive functioning of the primary motor cortex is a common finding in patients with chronic pain. Activation of the motor cortex is known to induce an analgesic effect in patients with chronic pain. In this exploratory study, we intend to verify if the mere observation of a movement could elicit activation of the motor cortical areas in patients with FM. Therefore, the purpose of this study was to examine the presence of MR in patients affected by fibromyalgia. We adopted a behavioral paradigm known for detecting the presence of MR and a neurophysiological experiment. Participants watched videos showing gripping movements towards a graspable or an ungraspable object, respectively, and were asked to press a button the instant the agent touched the object (Time-to-contact detection session). In a different experimental session, participants were only requested to observe and pay attention to the videos (Observation-only session). During each experimental session, the participants’ cerebral hemodynamic activity was recorded using the functional Near-Infrared Spectroscopy method. The behavioral task analysis revealed the presence of MR in both FM patients and healthy controls. Moreover, neurophysiological findings suggested that the observation of movement during the Observation-only session provoked activation and modulation of the cortical motor networks of FM patients. These results could represent evidence of the possible beneficial effects of movement observation in restarting motor activation, notoriously reduced, in FM patients.

“…Without such correction, we detected activation in a hypothesized area, right PMd/SFS. The activity of a region comprising PMd/SFS is related to linking successive action steps (Stadler et al, 2011;Schubotz et al, 2012;Hrkać et al, 2014;Pomp et al, 2021), and could contribute to updating the current event or action model with respect to each next segment (Kurby & Zacks, 2008;Tamber-Rosenau et al, 2011;Schubotz et al, 2012;Pomp et al, 2021).…”

“…We further expected to find elevated brain activity in the area of dorsal premotor cortex and adjacent prefrontal sites along the superior frontal sulcus (PMd/SFS) for structure expectancy violation. This region is characteristically active in stepwise ordinal linking of individual action steps, as required in quite different, but especially predictive, tasks [38,39,40,41,42](H3).…”

“…Structure modifications should elevate activity in premotor areas due to their central role in sequential order processing (Schubotz, 2004). Dorsal premotor and adjacent prefrontal sites along the superior frontal sulcus (PMd/SFS) were found for stepwise ordinal linking of individual action steps, as required in quite different, but especially predictive, tasks (Stadler et al, 2011;Schubotz et al, 2012;Tamber-Rosenau et al, 2011;Hrkać et al, 2014;Pomp et al, 2021). By contrast, content modifications were expected to engage areas related to object processing, including lateral occipitotemporal cortex (OTC) (Lingnau & Downing, 2015), anterior intraparietal sulcus (IPS) (Creem-Regehr, 2009;Schubotz et al, 2014), and fusiform gyrus (FG; Reber et al, 2005).…”

Episodic memories are not static but can be modified on the basis of new experiences, potentially allowing us to make valid predictions in the face of an ever-changing environment. Recent research has identified mnemonic prediction errors as a possible trigger for such modifications. In the present study, we investigated the influence of different types of mnemonic prediction errors on brain activity and subsequent memory performance using a novel paradigm for episodic modification. Participants encoded different episodes which consisted of short toy stories. During a subsequent functional magnetic resonance imaging (fMRI) session, episodic retrieval was cued by presenting videos showing the original episodes, or modified versions thereof. In modified videos either the order of two subsequent action steps was changed (violating structure expectancy) or an object was exchanged for another (violating content expectancy). While brain responses to structure expectancy violations were only subtle, content expectancy violations recruited brain areas relevant for processing of new object information. In a post-fMRI memory test, the participants’ tendency to accept modified episodes as originally encoded increased significantly when they had experienced expectancy violations during the fMRI session. Our study provides valuable initial insights into the neural processing of different types of mnemonic prediction errors and their influence on subsequent memory.
