The sulfide staining technique, known also as neo-Timm staining, predominantly stains associational fibres arising from cortical interneurons located primarily in the neuropil of layers I-III of the rat cerebral cortex. The density of these fibres, considered to have a possible role in cognitive and mnemonic processes, has been demonstrated to be related to the density of zinc-containing presynaptic buttons in the cerebral cortex. The unilateral injection of ibotenic acid into the nucleus basalis magnocellularis (NBM) resulted in no changes in the density of sulfide staining in the first 3 weeks after neurotoxin injection and in a significant loss of sulfide staining in the neuropil of cortical layers I-III 4 weeks after NBM lesion in the fronto-parietal cortex ipsilaterally to the lesion. These data suggest that unilateral lesioning of the NMB may cause changes of chemo-specific zinc-containing intracortical pathways. Moreover, they indicate that, in a manner similar to that described in the brain of Alzheimer's disease patients, NBM-lesioned rats show a decrease of zinc tissue stores in the fronto-parietal cortex.
