Nature Communications - The neural processes involved in memory formation for realistic experiences remain poorly understood. Here, the authors found that ripple-like activity in the human...

Learned suppression of distractor locations in visual search emerges through reactive mechanisms that involve initial spatial selection prior to suppression.

The perception of a stimulus can be accelerated by another that precedes it. Research to date has focused on quantifying this acceleration, and localizing it in the chain of perceptual and cognitive processes that are involved. This is challenging, because these processes may interact unexpectedly, and because traditional (univariate) analyses of brain activity and behaviour may conflate processes with the representations they act on. By using multivariate pattern analysis of EEG data from a missing element task, designed to measure the visual temporal integration of two successive stimulus displays, we were able to track the representation associated with the integrated percept. We manipulated the delay between our displays, and observed commensurate acceleration of the resultant integrated representation. Furthermore, regardless of the delay, we found that although processing was already accelerated during the earliest processing stages at around 100ms after stimulus onset, intermediate stages, at around 200ms, were even more accelerated. In contrast, later processing stages, at around 400ms, again showed less acceleration. The results thus suggest that perceptual acceleration during temporal integration is nonlinear, and that some time that is gained at one moment in the process can be lost again at another. ### Competing Interest Statement The authors have declared no competing interest.

I propose that temporal integration is ubiquitous in visual perception, because it serves an adaptive role. To support this idea, I draw together evid…

Spatial memory is a fundamental cognitive function that enables humans and other species to encode and recall the locations of items in their environments. Humans employ diverse strategies to support ...

Memories can be decoded from brain responses and eye movements. A combined electroencephalogram–eyetracking study now shows that learning is marked by dynamic shifts in brain patterns and eye movements that go from remembering the past to anticipating the future.

This study reveals how the brain dynamically shifts from learning to memory-guided behavior. Büchel et al. use electroencephalography (EEG) and eye tracking in a spatiotemporal learning task to show a...
