• Previous views on the cognitive functions of the basal forebrain cholinergic system often suggested that this neuromodulator system influences fundamental attentional processes but not learning. The results from an elegant series of studies by J. M. Maddux, E. C. Kerfoot, S. Chatterjee, and P. Holland (2007) reveal the intricate relationships between the levels of attentional processing of stimuli and the rate of learning about such stimuli. Moreover, their results indicate a double dissociation between the role of prefrontal and posterior parietal cholinergic inputs, respectively, in attentional performance and the learning rate of stimuli that command different levels of attentional processing. Separate yet interacting components of the cortical cholinergic input system modulate the attentional processing of cues that guide well-practiced performance or that serve as conditioned stimuli during learning.
