Sustaining attention to simple tasks: a meta-analytic review of the neural mechanisms of vigilant attention. (2013, background): “Similar effects were observed when comparing phasic alerting (i.e., performance in forewarned simple RT tasks) with intrinsic alerting (i.e., performance in continuous unwarned simple RT tasks), with the former imposing higher discrimination demands than the latter (Sturm & Willmes, 2001).”
The activation of attentional networks (2005, background): “…lesions of the frontal and parietal lobe, particularly of the right hemisphere, have strong effects on sustained attention and reduce the ability of patients to maintain the alert state in the absence of a warning signal (Posner and Petersen, 1990; Robertson et al., 1995; Sturm and Willmes, 2001).”
Insights into the neural basis of response inhibition from cognitive and clinical neuroscience. (2009, neutral): “…al., 2001), and working memory processes (D'Esposito et al., 1998), and in tasks that manipulate arousal (Kinomura et al., 1996; Sturm et al., 1999; Sturm and Willmes, 2001), or require participants to shift (Corbetta and Shulman, 2002; Yantis et al., 2002), or sustain attention (Coull et al.,…”
Functions of the Frontal Lobes: Relation to Executive Functions (2011, background): “E-mail: dstuss@rotman-baycrest.on.ca 759 necessary, studies must be based on patients with very carefully defined and limited focal frontal lobe lesions (see Stuss et al., 2005 for definitions).”
Typologies of attentional networks (2006, background): “Whereas alerting typically suggests goal-directed preparedness, arousal identifies general non-specific excitabilit”
Battery powered thought: Enhancement of attention, learning, and memory in healthy adults using transcranial direct current stimulation (2014, neutral): “Additionally, the fronto-parietal attention network that mediates alertness has been linked to both tonic/endogenous control of attention (vigilance) and phasic/exogenous attention (alerting attention; Sturm and Willmes, 2001). tDCS effects on vigilance have been examined only recently.”
Modulation of the semantic system by word imageability (2005, result): “Previous imaging studies have found greater activation in the thalamus and mesencephalic region in response to attentional alerting and orienting demands (for a review, see Sturm and Willmes, 2001).”
Development of attentional networks: An fMRI study with children and adults (2005, methodology): “Appropriate a priori hypotheses derived from previous work allowed limitation of the search volume in the dorsolateral prefrontal cortex, brainstem, thalamus, and extrastriate cortex for the alerting system (Coull et al., 2001; Sturm and Willmes, 2001; Thiel et al., 2004); the frontal eyefields, rig”
The Role of a Right Fronto-Parietal Network in Cognitive Control: Common Activations for Cues-to-Att (2006, background): “Midbrain-thalamic or brainstem networks have previously been associated with arousal in a number of studies in different modalities (Kinomura, Larsson et al. 1996; Sturm, de Simone et al. 1999; Sturm and Willmes 2001).”
40-second green roof views sustain attention: The role of micro-breaks in attention restoration (2015, background): “Efforts to maintain control of attention towards work tasks are processed cortically through the dorsal attention network (Paus et al., 1997; Sturm & Willmes, 2001), while external distractions are processed sub-cortically through the ventral attention network (Corbetta & Shulman, 2002; Maclean et…”
A Meta-Analysis of the Impact of Short-Term Sleep Deprivation on Cognitive Variables (2010, background): “…that vigilance and sustained attention are fundamentally important to many higher aspects of cognition and that these higher processes will necessarily decline if a subject is not able to sustain a sufficient level of vigilance while performing a task (Sturm et al., 1999; Sturm & Willmes, 2001).”
Optimal sustained attention is linked to the spectral content of background EEG activity: greater ongoing tonic alpha (∼10 Hz) power supports successful phasic goal activation (2007, background): “Although there is evidence that regions of the basal ganglia and the thalamus contribute to goaldirected behaviour as part of a broader more distributed fronto-striatal network (Sturm & Willmes, 2001; Kelly et al., 2004), it is unlikely that the LP1 is solely accounted for by subcortical activity.”
Cerebral correlates of alerting, orienting and reorienting of visuospatial attention: an event-related fMRI study (2004, methodology): “While some authors point to a right-sided fronto-parieto-thalamic network (Sturm and Willmes, 2001; Sturm et al., 1999), others suggest left lateralised parietal and frontal regions (Coull et al.”
The Attention System of the Human Brain: 20 Years After (2012, background): “An extensive imaging study (Sturm & Willmes 2001) showed that a largely common right hemisphere and thalamic set of areas are involved in both phasic and tonic alerting.”
