Intra-individual performance variability may be an important index of the efficiency with
which executive control processes are implemented, Lesion studies suggest that damage to …

We used fMRI to study the brain processes involved in the executive control of behavior. The
Sustained Attention to Response Task (SART), which allows unpredictable and predictable …

We combined the data of five event-related fMRI studies of response inhibition. The re-
analysis (n= 71) revealed response inhibition to be accomplished by a largely right …

Response inhibition and interference monitoring and suppression are two important aspects
of cognitive control. Previous functional imaging studies have suggested a common network …

Is there a single executive process or are there multiple executive processes that work
together towards the same goal in some task? In these experiments, we use counter …

Recent research yielded the intriguing conclusion that, in healthy adults, higher levels of
variability in neuronal processes are beneficial for cognitive functioning. Beneficial effects of …

Goal-directed behavior requires the continuous monitoring and dynamic adjustment of
ongoing actions. Here, we report a direct coupling between the event-related …

Thepresent study employed event-related fMRI and EEG to investigate the biological basis
of the cognitive control of behavior. Using a GO/NOGO task optimized to produce response …

Psychological and neurobiological theories of cognitive control must account for flexible,
seemless transitions among cognitive operations. When subjects switch between tasks, they …

The ability to suppress one's impulses and actions constitutes a fundamental mechanism of
cognitive control, thought to be subserved by the right inferior frontal cortex (rIFC). The …
