A Map of 32 Brain Peptides — Their Locations, Receptors, and Functions
Comprehensive review of 32 neuropeptides including opioid peptides, covering their brain distribution, synthesis, receptor binding, and proposed functions from a neurosurgical perspective.
Quick Facts
What This Study Found
32 brain peptides are categorized and reviewed across location, synthesis, receptor binding, and function, organized into opioid, pituitary hormone, and miscellaneous peptide groups.
Key Numbers
How They Did This
Narrative review summarizing published literature on 32 neuropeptides as of 1991.
Why This Research Matters
This review provided a useful reference map of brain peptides at a time when the field was rapidly expanding. It connects peptide discovery to clinical neurosurgery.
The Bigger Picture
This review captured the state of neuropeptide knowledge at a pivotal time, providing a reference framework that remains useful for understanding the brain's chemical complexity.
What This Study Doesn't Tell Us
Narrative review from 1991. Many details have been updated since. Broad scope limits depth on any single peptide system.
Questions This Raises
- ?How have the proposed functions of these peptides been updated since 1991?
- ?Which of these 32 peptides have led to clinical applications?
Trust & Context

What do these levels mean? →Frequently Asked Questions
Why are there so many brain peptides?
The brain uses peptides for fine-tuned communication over longer timescales than fast neurotransmitters. Different peptides serve different functions — from pain and mood to appetite and hormone control — allowing nuanced regulation of brain activity.
Are any of these 32 peptides used as drugs?
Several have led to clinical applications, including opioid analgesics (based on endorphin/enkephalin research), oxytocin for labor induction, and somatostatin analogs for hormone disorders.
