Sex differences

Recent articles

Large-scale neuroimaging datasets often lack information specific to women’s health, constraining AI’s analysis potential

Addressing this gap will require collecting widespread data on pregnancy, menopause and other life events women experience—and could bring us closer to the “holy grail” of linking brain and behavior.

Gene-activity map of developing brain reveals new clues about autism’s sex bias

Boys and girls may be vulnerable to different genetic changes, which could help explain why the condition is more common in boys despite linked variants appearing more often in girls.

Why we need basic science to better understand the neurobiology of psychedelics

Despite the many psychedelics clinical trials underway, there is still much we don’t know about how these drugs work. Preclinical studies represent our best viable avenue to answer these lingering questions.
