An illustration depicting the anatomical and cellular differences in male and female mice brains. The preoptic area of the brain is essential for sexual behaviors in male mice. An inset of the preoptic area is presented with male anatomical characteristics shown on the left side, and female characteristics on the right. The sexually dimorphic nucleus (SND) and principal nucleus of the bed nucleus of the stria terminalis (pBNST), highlighted in dark green and red respectively, are larger in male mice, while the anteroventral periventricular nucleus (AVPV), highlighted in yellow, is larger in
An illustration depicting the anatomical and cellular differences in male and female mice brains. The preoptic area of the brain is essential for sexual behaviors in male mice. An inset of the preoptic area is presented with male anatomical characteristics shown on the left side, and female characteristics on the right. The sexually dimorphic nucleus (SND) and principal nucleus of the bed nucleus of the stria terminalis (pBNST), highlighted in dark green and red respectively, are larger in male mice, while the anteroventral periventricular nucleus (AVPV), highlighted in yellow, is larger in females. A diagram is also included, comparing the differences in male (top row) and female (bottom row) brain cells. Male neurons (yellow) have twice as many dendritic spines as females. Immune cells known as microglia (blue) are in a more activated state in male brains, and contain shorter and thicker processes. Meanwhile, female astrocytes (green) have longer and more abundant extensions than their more compact male counterpart.
