Improvements in Memory after Medial Septum Stimulation Are Associated with Changes in Hippocampal Cholinergic Activity and Neurogenesis
Figure 3
Representative pictures showing the effects of the cholinergic lesion on the basal forebrain. The normal group had numerous ChAT immunopositive neurons in the MS (a). The lesion (b), implantation (c), and stimulation (d) groups displayed a loss of cholinergic neurons in the MS. Scale bar represents 500 μm. ChAT: choline acetyltransferase; MS: medial septum.
