Plain English Summary

Cortexin is a complex of low-molecular-weight, water-soluble polypeptide fractions derived from the cerebral cortex of cattle. It is primarily used in Russia and parts of Eastern Europe for its purported neuroprotective and nootropic properties, often investigated for the treatment of stroke, cognitive impairment, and neurological developmental disorders.
