Fascinatingly, in the last few years, it's been possible to do functional brain imagery, to do fMRI on people as they are hallucinating, and, in fact, to find that different parts of the visual brain are activated as they are hallucinating.
Fascinerende nok i de sidste par år har det været muligt at skabe funktionelle hjernebilleder, at lave fMRI på folk, mens de hallucinerer. Og faktisk at finde ud af, at forskellige dele af den visuelle hjerne aktiveres, mens de hallucinerer.
