The attentional blink refers to the transient impairment in perceiving the 2nd of 2 targets presented in close temporal proximity. In this article, the authors propose a neurobiological mechanism for this effect. The authors extend a recently developed computational model of the potentiating influence of the locus coeruleus-norepinephrine system on(More)
Neurophysiological work in monkeys has shown that changes in tonic and stimulus-induced activity in the noradrenergic brainstem nucleus locus coeruleus (LC) are tightly correlated with fluctuations in behavioral performance in a visual discrimination task. Simulation work suggests transitions between observed modes of LC activity may be mediated by changes(More)
