    "goal": "Induce spiritual, religious, or altered states of consciousness by applying weak, rotating magnetic fields to the temporal lobes.",
    "problem_addressed": "Lack of scientific understanding of how spiritual experiences arise in the brain and the desire to experimentally induce them.",
    "concept_summary": "A helmet fitted with solenoids generates a very weak rotating magnetic field (10 nT-1 uT) that targets temporal-lobe regions associated with religious experience. The field patterns are designed to mimic brain-derived signals, producing a sensed presence or other altered-state sensations in a majority of subjects.",
