Mapping Where Opioid Peptides Are Located in the Brain's Emotional Pain-Processing Cortex
Detailed mapping of enkephalin, dynorphin, and endorphin distribution in the rostral agranular insular cortex — a brain region processing pain's emotional component — revealed distinct opioid peptide laminar organization.
Quick Facts
What This Study Found
Immunohistochemical mapping revealed distinct laminar distributions of met-enkephalin, dynorphin, and beta-endorphin in the rostral agranular insular cortex — the brain's emotional pain processing region — providing the opioid peptide architecture for pain affect modulation.
