Figure 8

Quantitative analysis of cholinergic nerve fiber density in various layers of the aAOB and pAOB. (A) A low-magnification image of the AOB taken from a sagittal section. VAChT-ir positive nerve fibers are present in the GL, MCL and GCL. (B) Image of the enlarged middle AOB region that has been processed using Hessian-based feature extraction for automatic fiber count (for detailed method, see Krosnowski et al., 2012 and Sathyanesan et al., 2012). (C) Plot of VAChT-ir fiber density (Mean ± SEM, n = 3 mice). A higher density of VAChT-ir positive fibers is found in MCL and GCL than in the GL, with the fiber density in the pMCL trending toward being the highest. Scale: (A) 200 μm (B) 50 μm.
