Fig. 1From: The effect of nucleus basalis magnocellularis deep brain stimulation on memory function in a rat model of dementiaRepresentative photographs are showing the location of MS and the effect of cholinergic lesions on the MS. Figure (a) shows the location of MS in Atlas [24] and Figure (b) shows the location of MS in a brain slice stained with cresyl violet. The normal group had numerous ChAT-immunopositive neurons (c). The lesion (d), implantation (e), and stimulation (f) groups show a loss of cholinergic neurons. Scale bar represents 500 μmBack to article page
