- The study compared cortagen with cortexin, the polypeptide complex from which cortagen was derived. Cortexin showed anxiolytic-like effects when given acutely, with anxiogenic-like arousal emerging following repeated treatment.
- Cortagen, by contrast, provided motor stimulation without these emotional-affective fluctuations. This suggests that by isolating the specific tetrapeptide sequence, researchers achieved a more targeted effect with fewer confounding variables.
- Both agents stimulate neural growth in vitro, presumably in association with neurotrophic factors. However, their behavioral profiles differ, with cortagen showing a cleaner stimulatory effect.
