The whole hearts of neonatal lambs were subjected to histochemical detection of vagal
nerve fibres and ganglia. The methods included demonstration of acetylcholinesterase
(AChE) activity as a marker of cholinergic nerves and immunohistochemistry of tyrosine
hydroxylase (TH) an enzyme associated with bioaminergic fibres. The results showed
an abundance of epicardial ganglia distributed widely along ovine ventricular nerves
for some distance below the coronary groove. None of the ACHE positive ganglia were
positive for TH.
