Fig. 12.     A: Distribution of neurotensin-containing fibers/terminals and cholinergic cells at the level of the posterior part of the crossing of the anterior commissure. B: Schematic drawing from the same section showing that the ventral part of the globus pallidus contains a number of cholinergic projection neurons which are embedded in a heavy neurotensin-containing network. Bar Scale: 500µm. Abbrev. ac = anterior commissure; CP = caudate putamen; f = fornix; ic = internal capsule; MP = medial preoptic nucleus; Tu = olfactory tubercle; 3V = third ventricle.
