For more than 50 years, psychologists and neuroscientists have recognized the importance
of a working memory to coordinate processing when multiple goals are active and to guide …

Working memory is characterized by neural activity that persists during the retention interval
of delay tasks. Despite the ubiquity of this delay activity across tasks, species and …

When performing tasks, humans are thought to adopt task sets that configure moment-to-
moment data processing. Recently developed mixed blocked/event-related designs allow …

An important challenge in the design and analysis of event‐related or single‐trial functional
magnetic resonance imaging (fMRI) experiments is to optimize statistical efficiency, ie, the …

At any instant, our visual system allows us to perceive a rich and detailed visual world. Yet
our internal, explicit representation of this visual world is extremely sparse: we can only hold …

Human ability to attend to visual stimuli based on their spatial locations requires the parietal
cortex. One hypothesis maintains that parietal cortex controls the voluntary orienting of …

Echoplanar functional magnetic resonance imaging (fMRI) was used in normal human
subjects to investigate the role of the amygdala in conditioned fear acquisition and …

Cognitive neuroscience research on working memory has been largely motivated by a
standard model that arose from the melding of psychological theory with neuroscience data …

Cerebral hemodynamic responses to brief periods of neural activity are delayed and
dispersed in time. The specific shape of these responses is of some importance to the …

The inherently multivariate nature of functional brain imaging data affords the unique
opportunity to explore how anatomically disparate brain areas interact during cognitive …
