There's nothing unbelievable in this findings regardless of authenticity of these images. I know about at least one such case here in Russia, from my own fathers career, and he told me there were others. It's something people know about for quite a long time, at least in our country.

It is the particulars here that are unbelievable to me. Normal after hemespherectomy - sure, depending on the lobe, you will have fully intact language, hemiblindness but probably can regain motor function on the effected side after some time (depending on age). No cerebellum, nbd, cerebellum does not plan, initiate, or stop motor movement - it only corrects errors and has some putative cognitive roles.

What we have here is far more extreme: massive cortical tissue loss and compression, bilaterally. His striatum looks completely gone. There are many well studied and documented patients with far less tissue loss who suffer major cognitive and learning deficits. That makes this case here remarkable to me.

It's probably not a tissue loss, rather it's just undeveloped, as it was in the case I mentioned above. But nevertheless this probably should push nervous system to its limits to compensate such deficiency, so it's quite remarkable indeed.
