There is a brain washing machine operating in the University of Oulu.
>The operation of FUS LiFu is based on low-intensity, focused ultrasound. The device allows for the temporary opening of the blood-brain barrier and the delivery of water-soluble drugs to the precise location in the brain. Combining FUS technology with the specialized expertise in Oulu, the ultra-fast functional magnetic resonance imaging (fMRI), opens up entirely new possibilities in brain disease research.
