Research Overview
Arginine Vasopressin
Animal and human studies indicate vasopressin can modulate hippocampal and limbic circuits involved in learning and memory. The effect size is context dependent, and results vary by dose, route, and baseline cognitive state.
BDNF
BDNF is repeatedly associated with learning, long-term potentiation, and recovery from neurologic injury in preclinical literature. Direct protein delivery is difficult, so most studies focus on pathways that raise endogenous BDNF or on localized experimental administration.
