## Chapter 9/Figure 9.jpg Back | Home | Next | Distribution of different cell types in the neighborhood of identified NPY (A, C, E) and cholinergic (B, D, F) neurons. (A) and (B) Schematic drawings illustrating the location of the electrophysiologically and chemically identified neurons. (C) and (D) Coronal view of the identified neurons embedded into the same general region of the basal forebrain derived from a different database that contains four different cell populations. Filled circles: parvalbumin; up triangles: calretinin; down triangles: calbindin; squares: cholinergic neurons. The approximate number of cell bodies from each cell populations that can be found in the 3D volume of the single cell axonal arbor is indicated below. (E), (F) Enlarged view of the boxes from (C) and (D). Thicker, black indicates dendritic processes and thinner lines indicate axonal ramifications. Note the small varicosities along the axonal collaterals correspond to putative synaptic boutons.
