New study shows that the differences between male and female brains start in the womb

In a recent study, a team led by Moriah Thomason from New York University Langone scanned the brains of 118 fetuses in the second half of pregnancy. The researchers saw differences in how different brain regions connect together – but not everyone is convinced.

Thomason said: “Males are more susceptible to environmental influences than female babies”.

“We have previously seen that the prenatal brain of the female appears to be more robust, more linked to future behavior.”

“It’s almost as if the female brain has a tighter brain-to-outcome pairing.”

“If that’s true that could partially account for the fact the male is more vulnerable, and programmable.”

Thomason told The Times that culture does play a part in the differences between men and women, saying, “There are studies that show that sexual acculturation happens from day one, but I don’t see a good argument for the fact it is happening in the womb”.

However, other scientists said that the research was agenda-driven.

Gina Rippon, professor of cognitive imaging at Aston University said, “The differences begin before birth, the researchers say, they have potentially really interesting and innovative data which deserves better treatment than this”.

“In pursuit of a poorly defended hunt-the-difference agenda, they subjected their data to indefensibly weak statistical comparisons and drew unfounded conclusions.”
