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.
De xeito fascinante,  nos últimos anos, foi posible facer imaxes funcionais do cerebro, facer resonancias magnéticas funcionais mentres as persoas alucinaban. E, de feito, atopáronse as diferentes partes do cerebro visual que  se activaban mentres estaban sufrindo alucinacións.
