This is just one small component of brain repair.
Oddly, it seems that I am seeing more of this on HN lately.
NGF (Nerve Growth Factor) is added to dishes nearly every time such experiments are done to get neurons to grow. I'm sure they plated them on laminin or whatever substrate works best for those neurons as well. I haven't read the paper, but from the layman's description this sounds like hype.
