All-or-None Context Dependence Delineates Limits of FEF Visual Target Selection (Current Biology)

Visual neurons in the primate frontal eye field help guide eye movements. Now, Scerra et al. demonstrate that their contribution is limited: these cells distinguish targets from distracters prior to some, but not all, visually informed saccadic choices; they can select goals on the basis of saliency, but not on the basis of arbitrary visual features.
