The findings may help to better characterize normative development and altered patterns of brain activity that may serve as biomarkers for neurological conditions.

Researchers have found that while functional connectivity is highly individualized, there are aspects of the so-called connectotype that are both familial and heritable. “The connectotype demonstrated substantial heritability driven by high-order systems including the fronto-parietal, dorsal-attention, ventral-attention, cingulo-opercular, and default systems,” the researchers wrote. The findings may help to better characterize normative development and altered patterns of brain activity that may serve as biomarkers for neurological conditions including ADHD
