KATZENHIRN VIDEO


Damit jetzt niemand denkt wir hätten nur böses mit Hunden im Sinn, anscheinend ist es schon jemand 1999 gelungen Videobilder aus dem Hirn einer Katze zu grabben. Und so (s.o.) sollen sie ausgesehen haben. Erinnert mich schon wieder an Accelerando, das übrigens immer besser wird. :)

Using cats selected for their sharp vision, in 1999 Garret Stanley and his team recorded signals from a total of 177 cells in the lateral geniculate nucleus – a part of the brain’s thalamus [the thalamus integrates all of the brains sensory input and forms the base of the seven-layered thalamocortical loop with the six layered neocortex] – as they played 16 second digitized (64 by 64 pixels) movies of indoor and outdoor scenes. Using simple mathematical filters, the Stanley and his buddies decoded the signals to generate movies of what the cats actually saw. Though the reconstructed movies lacked color and resolution and could not be recorded in real-time [the experimenters could only record from 10 neurons at a time and thus had to make several different recording runs, showing the same video] they turned out to be amazingly faithful to the original.Mindpixel Blog: Brainpixels – Extracting Video from Cat Brains
