Maintaining visuospatial attention in spatiotopic coordinates requires updating of attentional representations following each eye movement.

To isolate purely visual memory, recognition was tested with sets of briefly-presented compound sinusoidal gratings, which minimized age-related differences in visual processing, and resisted verbal encoding. Recognition was measured after delays of 1, 2 or 4 seconds.

To investigate the role of attention in memory formation, we combined a variant of a spatial attention cuing task with a subsequent memory fMRI design. Scene stimuli were presented in the periphery to either the left or right of fixation, preceded by a central face cue whose gaze oriented attention to the probable location of the scene.

In contrast with this temporal association deficit, older adults are generally adept at using preexisting semantic associations, when present, to aid recall. We compared the use of temporal and semantic associations in young and older adults' word list recall following both free recall and serial recall instructions.

The current study examines the extent to which adaptation to time-compressed speech can be impeded by disrupting the continuity of the exposure sentences, and whether this differs between young and older adult listeners when they are equated for starting accuracy.

If the eyes move while a location in the visual field is facilitated, what happens to the internal representation of the attended location? With each eye movement, the retinotopic (eye-centered) coordinates of the attended location change while the spatiotopic (world-centered) coordinates remain stable.

To maintain stable spatiotopic (world-centered) representations, the relevant retinotopic (eye-centered) coordinates must be continually updated.

We conducted a spatial working memory task in which subjects remembered a cued location in spatiotopic or retinotopic coordinates while making guided eye movements during the memory delay.

Given limited capacity to process competing options, attentional mechanisms select, modulate, and sustain focus on information most relevant for behavior. A significant problem, however, is that attention is so ubiquitous that it is unwieldy to study. We propose a taxonomy based on the types of information that attention operates over-the targets of attention. At the broadest level, the taxonomy distinguishes between external attention and internal attention.

This can occur either directly from disorders that impair widespread bilateral regions of the cortex or indirectly through effects on subcortical arousal systems. It has therefore long been puzzling why focal temporal lobe seizures so often impair consciousness. Early work suggested that altered consciousness may occur with bilateral or dominant temporal lobe seizure involvement. However, other bilateral temporal lobe disorders do not impair consciousness.

Such prior work in humans suggests that the parahippocampal place area (PPA) represents scenes in a highly specific manner that can differentiate between different but overlapping views of a panoramic scene.

Although initial visual representations are necessarily retinotopic (eye centered), interaction with the real world requires spatiotopic (absolute) location information. We asked whether higher level human visual cortex���important for stable object recognition and action���contains information about retinotopic and/or spatiotopic object position.
