Objective: To analyze the behavioral and anatomical effects of discrete injections, in different groups of animals, of the same 192 IgG-saporin toxin into the basal forebrain nuclei and/or into the cerebellar vermis and hemispheres.
Summary: Authors administered, 192 IgG-saporin, selectively targeting cholinergic neurons in the basal forebrain and a subpopulation of cerebellar Purkinje cells, to adult rats bilaterally into the basal forebrain nuclei, the cerebellar cortices or both areas combined. The results suggest important functional interactions between the ascending regulatory inputs from the cerebellum and those arising in the basal forebrain nuclei that would act together to modulate the complex sensory–motor and cognitive processes required to control whole body movement in space.
Usage: (i) bilateral intraventricular injection of 192 IgG-saporin (ICV, n = 12); (ii) bilateral injections of 192 IgG-saporin into the basal forebrain nuclei (BF, n = 12); (iii) injections of 192 IgG-saporin into the cerebellar hemispheres and vermis (CBL, n = 12); and (iv) injections of 192 IgG-saporin into both the basal forebrain nuclei and cerebellar hemispheres and vermis (BF/CBL, n = 12).
