The issue focused on these factors in addition to standard biological differences (see earlier blog post). We discuss our findings and evidence for these differences in this blog post. In particular, we review how sex differences in genetic factors affect brain structure and function in humans and animals. We present evidence for sex differences in brain structure and function and discuss how these differences may explain sex differences in cognitive abilities. We discuss how sex differences in brain structure and function may explain sex differences in cognitive abilities in animals. We provide evidence for sex differences
