Here are some of the many myths that the meta-analysis has debunked in its review:
Certain brain regions like the corpus callosum – the brain part that connects the left and right hemispheres – that have always been thought as larger in females, which account for their “logic cum intuition thinking,” turned out to be just about the same size in males.
The amygdala, which serves as the main “impulse center” of the brain, largely identified as bigger in males, and has thus led to the popular perception that males are more “direct” to connect emotion and immediate action, turned out to be also the same size in females.
The hippocampus (for long-term memory), thought to be larger in women than in men (which is the basis of jokes for women remembering so much more in terms of their partners’ mistakes), did not turn out to be so.
Females came out in a few studies that they rely more on the right hemisphere for language while men rely more on the left side of their brains, but it turns out these studies did not significantly prove these differences.
Men were largely thought to predominantly use the left side of their brains (leading many to perceive women as less logical in the way they think) but the studies that concluded this did not come out with data significant enough to make them valid.
