(A) 3D wireframe diagram showing the distribution of cholinergic neurons
in the basal forebrain. Cholinergic cells (dots) were mapped from 12 sections,
approximately 300 microns apart. The contours of the corpus callosum and
the section outlines are marked. (B) Composite map illustrating the dendritic
architecture of the basal forebrain cholinergic system. The location of
panel (B) corresponds to the enclosed box in (A). Dendrites of approximately
1,300 cholinergic neurons were traced from 7 coronal sections. Diagonal
white lines delineate the approximate location of the corresponding major
forebrain areas. HDB= horizontal limb of the diagonal band; ic= internal
capsule; MS/VDB= medial septum/vertical limb of the diagonal band; SI= substantia
innominata. Scale bar: 1 mm (applies only to B). |
