Brain & nervous system: peptides in published research

Sources checked 2026-10-07 · 12 compounds · 24 cited studies

Scope: Brain, spinal cord, pineal gland and peripheral nerves. Each entry names the model and the tissue that a published study looked at, with the citation. It describes what was studied, not what was found, and a listing here is not a claim that a compound does anything in that organ.
