- Working Memory Capacity
- Baseline digit span 6–7 items; performance decay under cognitive load
- Digit span 7–9 items; sustained performance across extended task duration
- Improvement reflects BDNF-mediated synaptic strengthening in prefrontal cortex. Effect size comparable to moderate aerobic exercise
- Attentional Stamina
- Focus decline after 45–60 minutes on sustained attention tasks; subjective mental fatigue
- Focus maintained 90–120 minutes; reduced subjective fatigue ratings by 25–30%
- Melanocortin receptor modulation reduces HPA axis activation during cognitive demand. Performance under stress improves more than rested performance
- Stress Resilience
- Elevated cortisol response to acute stressors; subjective anxiety ratings 6–7/10 during high-demand periods
- Blunted cortisol response; subjective anxiety 3–4/10 under identical stressor conditions
- Anxiolytic effect without sedation distinguishes semax amidate from GABAergic anxiolytics. No impairment of reaction time or alertness
- Verbal Fluency
- Baseline verbal fluency 12–15 words per minute on category fluency tasks
- 16–20 words per minute; faster lexical retrieval and reduced tip-of-the-tongue episodes
- Dopaminergic modulation enhances executive function and language processing. Effect appears within 2–3 hours of administration
