~~~

Is human brain sexually dismorphic?

Answer 1

No
S/G (sex/gender) differences in the human brain are extremely subtle adn variable, they are relative to other source of individual variation. The difference usually portrayed as relating to s/g are more accurately attibutable to brain size.
In other words, the term “dimorphism” reinforces a binary understanding of s/g brain difference, when in fact, few such differences actually exist and the ones that do are very small, with great variability from population to population.

Question 2

What were the results of the review?

Abstract

Answer 2

Task-based fMRI has especially failed to find reproducible activation differences between men and women in verbal, spatial or emotion processing due to high rates of false discovery. Overall, male/ female brain differences appear trivial and population-specific. The human brain is not “sexually dimorphic.”
