The Differences in Sex in Babies

I'm not actually sure of any big studies that look at baby's brains apart from the one that you mentioned. I think the difficulty with doing newer imaging on babies is that they move their heads very often while they're in the newer imaging machine. And so there are a lot of like things that researchers can do to find differences that don't exist.

The causal structure here would be genes cause a difference in brain structure, which then causes a difference in observed sex differences. Two would be hormones that are hard coded cause brains to develop differently over time between male and
