Electron microscopic analysis of the mesencephalic ventromedial tegmentum in the cat.

We have studied the normal ultrastructure of the ventral mesencephalic tegmentum (VMT) in the cat, particularly the morphology and distribution of presynaptic terminals and the types of synaptic junctions. The following subnuclei of the region were examined: n. linearis rostralis (LR), n. paranigralis (PN), and n. interfascicularis (IF). The qualitative and… CONTINUE READING
