6. Body ownership alterations emerge from proprioceptive impairment and frontoparietal network damage

COEX 

The sense of body ownership refers to the feeling that our body belong to us and it plays a crucial role in our perception of our body's position and movement. Alterations in the sense of ownership for the contralesional upper limb are relatively common in the acute phase after cerebral stroke, with patients experiencing difficulties in self-attributing the affected limb, visually perceived, or persistently denying ownership of it (i.e., somatoparaphrenia). Our understanding of the pathophysiological mechanisms underlying these alterations is still poor, limiting the development of effective neurorehabilitative approaches.
Body ownership shares its neural substrate with multisensory integration processes and motor control. According to most accepted accounts, sensorimotor and multisensory integration deficits are key factors determining body ownership alterations in stroke patients; however experimental evidence supporting this view is scarce.
