title: The cholinergic input to the superficial layers of the superior colliculus: an ultrastructural immunocytochemical study in the ferret.
abstract: The cholinergic innervation of the superficial layers of the ferret's superior colliculus was investigated with a combination of electron microscopy and choline acetyltransferase immunohistochemistry. Cholinergic boutons in the superficial layers of the superior colliculus possess spherical vesicles and make predominantly asymmetrical synapses onto the profiles of small dendrites, as do the terminals of cortical and retinal axons. In most areas of the brain studied so far, cholinergic terminals tend to form synapses of the symmetrical variety.
