This study used functional Magnetic Resonance Imaging to investigate the brain areas involved in illusory sensations of touch. It was found that these experiences were mediated by decision-making areas in the medial parietal and medial prefrontal cortex, rather than in primary sensory areas; providing provide evidence for a top-down influence on somatic misperception.
