High-field FMRI reveals brain activation patterns underlying saccade execution in the human superior colliculus.
(PloS one, 2010)BACKGROUND: The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye- and head-movements. The knowledge about the function of this structure is mainly based on single-unit ... -
Pinning down response inhibition in the brain--conjunction analyses of the Stop-signal task.
(Neuroimage, 2010-10-01)Successful behavior requires a finely-tuned interplay of initiating and inhibiting motor programs to react effectively to constantly changing environmental demands. One particularly useful paradigm for investigating inhibitory ... -
Rapid modulation of sensory processing induced by stimulus conflict.
(J Cogn Neurosci, 2011-09)Humans are constantly confronted with environmental stimuli that conflict with task goals and can interfere with successful behavior. Prevailing theories propose the existence of cognitive control mechanisms that can suppress ... -
Reward associations reduce behavioral interference by changing the temporal dynamics of conflict processing.
(PLoS One, 2013)Associating stimuli with the prospect of reward typically facilitates responses to those stimuli due to an enhancement of attentional and cognitive-control processes. Such reward-induced facilitation might be especially ... -
Strategic allocation of attention reduces temporally predictable stimulus conflict.
(J Cogn Neurosci, 2012-09)Humans are able to continuously monitor environmental situations and adjust their behavioral strategies to optimize performance. Here we investigate the behavioral and brain adjustments that occur when conflicting stimulus ... -
The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ... -
The influence of different Stop-signal response time estimation procedures on behavior-behavior and brain-behavior correlations.
(Behav Brain Res, 2012-04-01)The fundamental cognitive-control function of inhibitory control over motor behavior has been extensively investigated using the Stop-signal task. The critical behavioral parameter describing stopping efficacy is the Stop-signal ... -
The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task.
(PLoS One, 2011)Inhibitory motor control is a core function of cognitive control. Evidence from diverse experimental approaches has linked this function to a mostly right-lateralized network of cortical and subcortical areas, wherein a ...
