Have you read the PDF given?

The whole nail part is basically a single sentence in the paper.

For example, decorticate rats are unable to escape narrow alleyways because they can not turn around due to their tonsils touching the walls and them being unable to ignore that feeling.

Another example is that they take a few seconds vs (!) 5 minutes to groom themselves on average.

Yes! I got interested in this when my colleague worked with a person who had an entire hemisphere resected as a teenage.

FWIW, the nail thing is a bit of a neuroscience meme. I heard--and stole--this quip from multiple people in several different situations. There's also a really striking figure in that chapter (p. 7 or 8).

No argument that the rats' behaviors are affected. I suppose whether you find the slowness of their grooming expected (because of brain damage) or impressive (because it happens at all) is a matter of taste. Glass^W Skull half-empty or half-full, if you will.

They are not slow, they just stop grooming themselves well enough.
