Abstract
The distribution of met-enkephalin in the
limbic system of the cat brain and its modification after
low frequency electroacupuncture (EA) stimulation have
been studied experimentally using the indirect
immunocytochemistry technique. A marked increase of
post-stimulation met-enkephalin immunoreactivity was
observed in the tractus habenulo-penduncularis, tractus
mamilo-thalamicus, and media1 forebrain bundle, and a
decrease at the leve1 of the nucleus interpeduncularis,
medialis dorsalis, stria terminals, septalis lateralis,
septalis medialis, accumbens septi, supraopticus, and
amygdaloideus centralis. The experimental results link
the changes in immunoreactivity (and therefore the
structures in which they take place) with the action of
low frequency EA, and permit the conclusion that the
met-enkephalinergic portion of the limbic system studied
is directly related morpho-functionally with analgesia
and the anatomic pathways of pain.
