"The very satisfying answer is that the gene did exactly everything that you could have hoped for."
The results can be broken down into four sections. By inserting the gene:
The size of the monkeys' neocortex increased
Folding of the brain, similar to how a human brain is folded was induced
The relevant pro-generative cell type, which produces neurons, was increased
Specifically, it increased upper-layer neurons, which are the neurons that increase during evolution
"This shows, basically, that the gene — and its expression in humans — is sufficient to expand and to fold the primate, or the monkey, brain," co-author of the study, Michael Heide said.

After about 100 days after the fetus had been growing, the international team unanimously agreed to remove the fetus through a C-section. Bringing a "new human-gene-influenced monkey into this world would step over the ethical line," said Huttner. "
