Abstract
Illusory own-body perceptions are 'body in space' misinterpretations of the brain and belong to the class of out-of-body experiences wherein the angular gyrus seems importantly implicated. In the present study additional cerebellum involvement in illusory own-body perceptions was investigated in a healthy young female right-handed volunteer. Transcranial magnetic stimulation (TMS) was applied over the cerebellum. Placebo cerebellum TMS and occipital TMS served as control conditions. Illusory own-body perceptions accompanied by electric brain activity over the somatosensory cortex were only observed after cerebellum TMS. The data provide the first evidence that the cerebellum might be involved in a neuronal network underlying illusory own-body perceptions.
