Gedankenlesen für Fortgeschrittene

Schaut euch das Video dazu an. Unglaublich was bereits möglich ist. Der Proband lag dafür in einem fMRI und sah sich die links gezeigten Filmausschnitte an. Rechts sieht man die aus den Hirnströmen berechneten Bilder, die auf Basis von 18 Millionen Sekunden Youtube-Clips produziert werden. Erstaunlich!


Interessantes Detail aus dem FAQ zu diesem Paper:

At some later date when the technology is developed further, will it be possible to decode dreams, memory, and visual imagery?

Neuroscientists generally assume that all mental processes have a concrete neurobiological basis. Under this assumption, as long as we have good measurements of brain activity and good computational models of the brain, it should be possible in principle to decode the visual content of mental processes like dreams, memory, and imagery. The computational encoding models in our study provide a functional account of brain activity evoked by natural movies. It is currently unknown whether processes like dreaming and imagination are realized in the brain in a way that is functionally similar to perception. If they are, then it should be possible to use the techniques developed in this paper to decode brain activity during dreaming or imagination.
