Summary of the rats' performance on an olfactory version of the 5-CSRTT across different testing conditions, following the cholinergic NBM lesion. Note the significant group differences in the percentage of correct responses and percentage of omissions per session under the conditions of increased attentional demand.

*Reflects group difference at p < 0.05.
