The ascending cholinergic projections of the pedunculopontine and dorsolateral tegmental nuclei, referred to collectively as the pontomesencephalotegmental (PMT) cholinergic complex, were investigated by use of fluorescent tracer histology in combination with choline-O-acetyltransferase (ChAT) immunohistochemistry and acetylcholinesterase (AChE)(More)
The morphologies, intercellular organization, and cortical projection patterns of putative cholinergic neurons in the basal forebrain of the rat were examined by use of fluorescent tracer histology in combination with the pharmacohistochemical regimen for acetylcholinesterase (AChE). Intensity staining AChE-containing cells projecting to frontal(More)
The cholinergic innervation of the compact and reticular parts of the substantia nigra in the rat was investigated by use of highly sensitive retrograde and anterograde tract-tracing methods in combination with choline acetyltransferase immunohistochemistry. The fluorescent tracers True Blue, propidium iodide, or fluorogold were infused preferentially into(More)
The cholinergic projections to the limbic telecephalon in the rat were investigated by use of fluorescent tracer histology in combination with choline-O-acetyltransferase (ChAT) immunohistochemistry and acetylcholinesterase (AChE) histochemistry (pharmacohistochemical regimen). Propidium iodide or Evans Blue was infused into the olfactory bulb, hippocampus,(More)
The postnatal development of cholinergic projection and local-circuit neurons in the rat forebrain was examined by use of choline acetyltransferase (ChAT) immunohistochemistry and acetylcholinesterase (AChE) histochemistry. Although regional nuances were apparent, a general trend emerged in which cholinergic projection neurons in the basal nuclear complex(More)
Sequential immunohistochemical demonstration of nerve growth factor receptor and cholinergic acetyltransferase on the same tissue section in the rat revealed that approximately 92% of all cholinergic neurons in the basal forebrain possessed that receptor. Only 0.9% of the neurons demonstrating nerve growth factor receptor in the basal nuclear complex lacked(More)
The origins and acetylcholinesterase (AChE, EC 3.1.1.7) content of neurons projecting to the AChE-rich basolateral amygdala were studied by infusing Evans Blue (EB), a retrogradely transported fluorescent label, into that neural region and, following microscopic evaluation of labelled somata, staining the same tissue sections for AChE according to the(More)
Descending projections from cholinergic neurons in the pedunculopontine and laterodorsal tegmental nuclei, collectively referred to as the pontomesencephalotegmental (PMT) cholinergic complex, were studied by use of the fluorescent retrograde tracers fluorogold, true blue, or Evans Blue in combination with choline acetyltransferase (ChAT)(More)
Digoxigenin-labeled riboprobes and in situ hybridization of choline-O-acetyltransferase mRNA, both alone and in combination with immunohistochemical procedures for the synthetic enzyme of acetylcholine, were used to map the topography of putative cholinergic neurons in the rat central nervous system. Only the anti-sense riboprobe yielded specific labeling,(More)
