🧠 Female VS Male Male brains are slightly heavier at nearly 1,400 grams, while female brains average about 1,300 grams. Women have more white matter and men have more gray matter. The white matter is responsible for the connections between the hemispheres and all parts of the brain. Without white matter, the brain would not be able to work coherently. Another function of the white matter is data transfer. Gray matter is responsible for perception of the world, memory, speech, and feelings. It is hard to say who is luckier, but both men and women have their advantages.
