The activations of the anterior and
posterior cingulate gyrus and the dorsomedial prefrontal cortex further support the assumption that the perception of chemosensory anxiety signals might release feelings of empathy.
The most prominent effects between full - scale IQ and normalized path length were found in medial prefrontal gyrus (Brodmann area 9/10, r = − 0.75, p = 0.001, df = 18, yellow box), precuneus /
posterior cingulate gyrus (BA 7/31, r = − 0.55, p = 0.014, df = 18, orange box), and bilateral inferior parietal regions (BA 39/40, right inferior parietal: r = − 0.72, p = 0.001, df = 18 depicted in red box; left inferior parietal: r = − 0.68, p = 0.001, df = 18).
Strong associations between full - scale IQ and individual normalized path length were found in medial prefrontal gyrus, precuneus /
posterior cingulate gyrus, and bilateral inferior parietal regions (Fig. 3).

the posterior cingulate gyrus.
Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri,
posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.
