Reminds me of cyberbrain sclerosis from Ghost In The Shell.

Which is precisely what this has solved!

Ah, well that is exciting then (I did watch the video and know they said the pig had the unit for two months, but I wasn't sure if they had actually solved it or not, although two months is certainly a great sign).
