title: Norepinephrine as principal catecholamine in a specific neurone of an invertebrate (Boophilus microplus: Acarina).
abstract: Norepinephrine has been identified as the principal catecholamine in individual neurons of the synganglion of an arthropod, the cattle tick Boophilus microplus. This suggests that norepinephrine may have a hitherto unsuspected major physiological role in at least one group of invertebrates.
