" neurophysiologist Olaf Blanke, who came across the phenomenon unexpectedly. He had triggered it with electrical stimulation to the temporal parietal cortex of a patient’s brain while trying to locate the focus of a seizure.8 He has also studied a bevy of patients who complain of an FoP. He found that lesions in the frontoparietal area are specifically associated with the phenomenon and are on the opposite side of the body from the presence.9 This location suggested to him that disturbances in sensorimotor processing and multisensory integration may be responsible. While we are conscious of our location in space, we are unaware of the multitude of processes (vision, sound, touch, proprioception, motor movement, etc.) that, when normally integrated, properly locate us there. If there is a disorder in the processing, errors can occur and our brains can misinterpret our location. Blanke and his colleagues have found that one such error manifests itself as an FoP. Recently, they cleverly induced the FoP in healthy subjects by disordering their sensory processing with the help of a robotic arm.10 "
