title: The state of cholinergic structures in forebrain of bulbectomized mice.
abstract: The effects of bulbectomy on the state of basal forebrain cholinergic structures and spatial memory in Morris water maze were studied. Immunostaining with polyclonal antibodies to choline acetyltransferase AB144P revealed decreased density of immunoreactive cells in the horizontal limb of the diagonal band of Broca (55% of control), basal magnocellular preoptic nucleus (58.9%), and the caudate nucleus-putamen complex (68.2%). No significant changes in the vertical limb of the diagonal band of Broca and globus pallidus were observed. These findings and published data allow us to assume that pathology of the olfactory bulb can underlie memory impairment during Alzheimer's disease associated with dysfunction of acetylcholine-synthesizing structures in the forebrain.
