Having said that, there's some very recent research to suggest that memories / neuronal weights are actually encoded directly in neuronal DNA.

(this does not mean that this DNA is directly heritable, since it does not necessarily end up in the gametes, but it is still interesting that, yes, in fact, it involves DNA change)

So, you're referring to encoding via DNA? Why not just say that explicitly rather than refer to some occluded understanding of the word "gene"?

This also seems to be a semantic distinction largely irrelevant to understanding the article as presented.
