Abstract
AbstractThis chapter offers a snapshot of the current state of the burgeoning literature on the neural mechanisms of top-down attentional control. It starts by reviewing three neuroanatomical models of visuospatial attention. This review of these models is intended to provide an anatomical framework for understanding the empirical research presented in later sections. It then describes some of the current literature investigating the neural mechanisms of top-down control. These studies of the top-down control of visuospatial attention can be divided into two categories: those studies aimed at determining where control systems are located in cortex, and those that are aimed at determining how control is manifest in cortex. In addition, it reports some of the authors' work that is aimed at understanding the generality of spatial attentional control mechanisms. It concludes by proposing new lines of research that, when combined, will move towards a more complete understanding of top-down attentional control.
