Key Findings
- Semax reduces impulse activity of cortical neurons in cats
- The inhibitory effect of semax is linked to stimulation of M‑choline (muscarinic) receptors
- The study used microelectrode recordings in immobilized cats, not humans
Practical Outcomes
- For biohackers, the main takeaway is that semax appears to modulate brain activity through cholinergic pathways, but the study provides no dosage or protocol for humans. It’s a mechanistic clue rather than a ready‑to‑use recommendation, and further human research is needed before applying it to longevity or performance regimens.
Summary
In a cat study, the brain‑boosting peptide semax was found to calm down individual brain cells in the cortex, and this calming effect seems to involve the brain's M‑choline (muscarinic) receptors. The research was done on immobilized cats using tiny electrodes, so it doesn’t give direct guidance for people, but it hints at how semax might work in the brain.
Abstract
The effect of nootropes (semax, mexidol, and GVS-111) on the activity of individual neurons in various cerebral cortex regions was studied by microelectrode and microionophoresis techniques in cats immobilized by myorelaxants. It was established that the inhibiting effect of mexidol upon neurons in more than half of cases is prevented or significantly decreased by the GABA antagonists bicuculline and picrotoxin. The inhibiting effect of semax and GVS-111 upon neurons in more than half of cases is related to stimulation of the M-choline and NMDA receptors, respectively.
