TL;DR: Dorsal anterior cingulate cortex/medial superior frontal cortex and bilateral anterior insula/frontal operculum showed reliable start-cue and sustained activations across all or nearly all tasks and carried the most reliable error-related signals in a subset of tasks, suggesting that the regions form a "core" task-set system.
Journal ArticleDOI
The neural bases of momentary lapses in attention.
TL;DR: It is determined that attentional lapses begin with reduced prestimulus activity in anterior cingulate and right prefrontal regions involved in controlling attention, and increased stimulus-evoked activity in the right inferior frontal gyrus and the right temporal-parietal junction predicted better performance on the next trial.
Journal ArticleDOI
Functional neuroanatomical differences between adults and school-age children in the processing of single words.
Bradley L. Schlaggar,Timothy T. Brown,Heather M. Lugar,Kristina M. Visscher,Francis M. Miezin,Steven E. Petersen +5 more
TL;DR: Direct comparisons of brain activation in the left frontal and extrastriate cortex were made in adults and children performing single-word processing tasks with visual presentation, suggesting that maturation of the pattern of regional activations for these tasks is incomplete at age 10.
Journal ArticleDOI
Mixed blocked/event-related designs separate transient and sustained activity in fMRI.
Kristina M. Visscher,Francis M. Miezin,James E. Kelly,Randy L. Buckner,David I. Donaldson,Mark P. McAvoy,Vidya M. Bhalodia,Steven E. Petersen +7 more
TL;DR: Evidence is provided that mixed designs are an effective tool for separating transient, trial-related activity from sustained activity in fMRI experiments and can allow researchers a means to examine brain activity associated with sustained processes.
Journal ArticleDOI
Ventral tegmental area/midbrain functional connectivity and response to antipsychotic medication in schizophrenia.

TL;DR: The findings suggest that VTA/midbrain resting-state connectivity may be a useful biomarker for the prediction of treatment response.
