LC (Locus ceruleus) projects to MY (Medulla)

Human alpha-synuclein expressed only in medullary neurons was later found in axonal fibres within the pontine coeruleus–subcoeruleus complex, some of which were also tyrosine hydroxylase positive, taken as evidence of protein transfer along the direct projection these cells send to the medulla.

Made by an AI model reading the paper (claude-opus-5, extract@0.3.0); a second AI model (claude-opus-5) agrees.
