Number (mean ± SEM) of ChAT- and parvalbumin-IR cells in basal forebrain subregions

	Control	Saporin	Reduction, %	p
ChAT
NBM	355.89 ± 9.45	161.60 ± 6.19	54.6	<0.001*
MS/VDB	394.33 ± 8.59	379.10 ± 9.01	3.9	0.134
HDB	128.56 ± 6.09	127.60 ± 5.80	0.7	0.884

Summary of the findings following the ChAT and parvalbumin immunostaining shows that there was a significant loss of cells in the NBM of ACh-NBM-lesioned rats compared to sham-lesioned rats. There were no group differences in the number of ChAT-immunoreactive cells in the MS/VDB and in the HDB, and no differences in the number of parvalbumin-immunoreactive cells in the NBM.

*Indicates significant difference at p < 0.05.
