tele‐Methylimidazoleacetic acid (t‐MIAA), a major brain histamine metabolite, was measured in nine rat brain regions by a gas chromatography‐mass spectrometric method that also measures the precursor amine,tele‐methylhistamine (t‐MH). The t‐MIAA concentration of cerebellum, medulla‐pons, midbrain, caudate nucleus, hypothalamus, frontal cortex, hippocampus, and thalamus varied 15‐fold, hypothalamus showing the highest level (2.21 nmol/g) and cerebellum the lowest (0.15 nmol/ g). The concentrations of t‐MIAA and t‐MH were significantly correlated in all regions except midbrain, which had relatively more t‐MIAA. Probenecid did not alter whole‐brain t‐MIAA levels. Treatment with pargyline, an inhibitor of monoamine oxidase, lowered the t‐MIAA levels in all regions.
