Acetylcholine and norepinephrine are widespread neuromodulators in the brain, having a rich variety of functions subserved by a diverse range of mechanisms. Many groups have studied their roles in cognitive tasks, particularly ones involving various forms of attention and plasticity.  A recent focus of work on these neuromodulators, and others such as dopamine and serotonin, has been on their specific contributions to learning and inference. One suggestion has been that they represent very particular forms of information necessary for inference and learning, and that insight into their individual and interacting functions can be gained by casting them into these terms.
This workshop aims to bring together a quorum of the key research groups working on ACh and NE, in order to discuss the separate and combined roles of these neuromodulators. Apart from assembling peopleworking on the same systems at very different levels of analyses (computational, behavioral, neurophysiological and neuropharmacological), major objectives of the workshop include illuminating the interactions between ACh and NE, attempting to elaborate consensus view of the forms of attention and other cognitive tasks in which they are involved, and establishing or delineating the foundations of a statistical approach to understanding their functions.
