Analogy between shifting the focus of gaze and a jump back in time. a. Top: When the gaze is focused on the young scientist at the center, decreasing acuity with distance from the fovea makes objects in the periphery difficult to distinguish. One windmill can barely be discerned. Middle: If the gaze is shifted to the windmill, nearby objects (e.g., the windmill on the left) and their spatial relationships become distinguishable. Bottom: The gradient of acuity across the physical image changes as the gaze shifts. b. A neural recency effect. Ensembles of single units were recorded from human epilepsy patients during presentation of a list of pictures. The population vector at each moment was compared to population vectors from preceding moments. c. A neural jump back in time. When a picture from the list was presented the population vector was compared to the earlier population vectors as a function of the distance from the original presentation of the remembered picture (b and c after [49]).
