Some parasympathetic neurons in the guinea-pig heart express aspects of the catecholaminergic phenotype in vivo.

Cell and tissue research - 1 Aug 1990

Abstract excerpt

In a histochemical study of intrinsic cardiac ganglia of the guinea-pig in whole-mount preparations, it was found that some 70-80% of the neurons express aspects of the catecholaminergic phenotype. These neurons have an uptake mechanism for L-DOPA, and contain the enzymes for converting L-DOPA (but not D-DOPA) to dopamine and noradrenaline, i.e. aromatic L-aminoacid decarboxylase and dopamine beta-hydroxylase....
