  • Transient inactivation of the superior colliculus in primates during a motion-change-detection task is shown to lead to large deficits in visual attention while the enhanced response of neurons in the visual cortex to attended stimuli remains unchanged; this shows that processes independent of those occurring in the visual cortex have key roles in visual attention.

  • Superior colliculus (SC) and frontal eye fields (FEF) contain visuo-motor maps but their contributions to selective attention are not fully understood. Here, the authors perform reversible inactivations of the SC or FEF and report that loss of SC activity has a more devastating effect on attention.

  • Our perception of the visual world is stable despite saccade-caused retinal input shifts. A new behavioral study shows that this stability may be achieved by predictively remapping attention before eye movements begin.

  • Herman et al. exploit the reliable effects of perturbing superior colliculus (SC) neuronal activity on perceptual choice behavior to demonstrate a plausible mechanism by which SC may contribute to perceptual judgments during covert attention tasks.

  • Selecting relevant information to make perceptual judgements is usually thought to be a cortical function. By reversibly deactivating the superior colliculus in monkeys, this study demonstrates that activity in a subcortical structure can also inform perceptual judgements, even in the absence of orienting movements (a function previously attributed to the superior colliculus).

  • A new study shows that activity in the superior colliculus encodes the distance to the goal of the orienting movement, not the particular saccade or saccades used to get there.
