Brain dynamics and cognition share genetic roots. Criticality may guide future brain health research. A recent study published on June 24 in PNAS presents strong evidence that brain criticality—the delicate balance between neural excitation and inhibition—is heavily influenced by genetic factors and closely linked to cognitive abilities. The research, led by Prof. Ning Liu of […]



Summary

A new study in PNAS reveals a strong genetic basis for brain criticality, the balance between neural excitation and inhibition, and its link to cognition. Led by Prof. Ning Liu, the research demonstrates that individual genetic variations significantly impact brain criticality levels. This suggests that genetic predispositions influence both brain dynamics and cognitive performance. The findings highlight the potential of using criticality as a biomarker for future research into brain health, offering insights into understanding and potentially addressing cognitive disorders through a genetic lens.
