Research Overview
NGF
NGF is one of the most established growth factors in neurobiology and has been investigated for both central and peripheral neuronal repair. Its strongest cognitive relevance comes from supporting basal forebrain cholinergic neurons and downstream memory circuitry.
Noopept
Noopept has been reported to increase NGF/BDNF-related signaling and improve performance in tasks involving learning and recall. Evidence includes preclinical studies and small human studies, but the overall literature is still modest compared with mainstream cognitive drugs.
