People who’ve had an out-of-body experience (OBE) report that their conscious awareness shifted outside their physical body – often upwards, so they felt like they were floating above their own head.
It’s thought that OBEs occur when the brain fails to properly integrate data from the different senses, including vision, touch, proprioception (the sense of where the limbs and other body parts are located in space) and from the vestibular system (organs in the inner ear that monitor head orientation, balance and motion).
Previous research has mostly focused on the role of vision and touch – for example by triggering the illusion of viewing one’s own body – but the vestibular system has largely been neglected. If it does play an important role we should expect that problems with the vestibular system – which often present as feelings of dizziness – lead to OBEs, but do they?
Historical case studies suggested that they might. And now, published in Cortex, the first systematic study of patients referred to a neurological specialist because of dizziness has found that they can.
