Description

While the study shows rapamycin enhances both neurogenesis and cognitive capacities, the causal relationship and intermediate steps between enhanced autophagy and behavioral improvements are not mechanistically explained. This gap limits understanding of how cellular-level autophagy changes produce functional brain improvements.
