Key Findings
- Selank (300 µg/kg) improved learning, memory, and attention in adult rats with early‑life catecholamine system damage.
- The damage was induced by 6‑hydroxydopamine, a toxin that selectively destroys dopamine‑related neurons.
- The study was performed in Wistar rats, not humans, and used a specific developmental injury model.
Practical Outcomes
- For biohackers, the results are not directly actionable because they come from an animal model with a very specific brain injury that most people do not have. While the data hint that selank might support cognition under certain neurological stress, there is no human dosage, safety, or protocol to apply. More research in humans would be needed before considering selank for cognitive enhancement.
Summary
In a rat study, scientists gave a peptide called selank to adult animals that had their brain's dopamine system damaged early in life. The treated rats showed better learning, memory, and attention compared to untreated ones, suggesting selank can partially reverse the cognitive problems caused by that early damage.
Abstract
Effects of selank on learning, memory, and attention to sensory stimuli of different modality were studied in adult Wistar rats treated with 6-hydroxydopamine (neurotoxin selectively damaging catecholaminergic neurons and their terminals) during the first 3 days of life. Selank (300 microg/kg) restored cognitive processes disordered by chronic artificial inhibition of the cerebral catecholaminergic system.
