Both sets of data may suggest that the atten- tional processing of distinct stimuli is disrupted following cholinergic depletion from latter cortical regions. It is workable, however, that the depletion of ACh from caudal or rostral cortical regions by oneself may be insufficient to damage display of some tasks, whereas combined depletions may have more than additive effects (70). Other investigators have auxiliary argued that the choliner- gic innervation of rostral.

Discriminative excitotoxic lesions or phar- macologic manipulation of the core basalis has also been reported to harm doing in a five-choice serial reac- tion piece of work that requires animals to scent and counter to short visual stimuli (73). Interestingly, the observation that appetitive pavlovian learning in regard to a individual remind is enhanced after core basalis lesions (74) suggests that attentional processing of discontinuous cues may not be affected sooner than depletion of ACh from the rostral neocortex except when divided concentration is required.
