Chronic stroke and aging: the impact of acoustic stimulus intensity on fractionated reaction timeStephen A Coombes
Department of Psychiatry, Department of Kinesiology and Nutrition, University of Illinois at Chicago, 1919 West Taylor, 650 AHSB M C 994, Chicago, IL 60612, United States
Neurosci Lett 452:151-5. 2009..Findings are integrated with previous evidence concerning post stroke corticospinal tract integrity and are interpreted via mechanisms which address stroke and age-related changes in motoneurons and activity in motor units...
Attentional control theory: anxiety, emotion, and motor planningStephen A Coombes
Department of Psychiatry, and Department of Kinesiology and Nutrition, University of Illinois at Chicago, 650 AHSB M C 994, Chicago, IL 60612, USA
J Anxiety Disord 23:1072-9. 2009..We conclude that increased stimulus-driven attentional control interferes with movements that require greater attentional resources...
Emotion and motor preparation: A transcranial magnetic stimulation study of corticospinal motor tract excitabilityStephen A Coombes
University of Illinois, Chicago, 60612, USA
Cogn Affect Behav Neurosci 9:380-8. 2009..Moreover, they validate the action readiness component of emotional experience by demonstrating that emotional states influence the execution of future movements but, alone, do not lead to overt movement...
Selective regions of the visuomotor system are related to gain-induced changes in force errorStephen A Coombes
Department of Kinesiology and Nutrition, University of Illinois at Chicago, 1919 West Taylor, 650 AHSB, M C 994, Chicago, IL 60612, USA
J Neurophysiol 103:2114-23. 2010..Instead, specific regions of the visuomotor system selectively change in activity related to large changes in force error and large changes in the spatial amplitude of visual feedback...
Spatiotemporal tuning of brain activity and force performanceStephen A Coombes
Department of Kinesiology and Nutrition, University of Illinois at Chicago, Chicago, IL 60612, USA
Neuroimage 54:2226-36. 2011..This study demonstrates that the frequency of visual feedback drives where in the brain visual gain mediated reductions in force error are regulated...
Emotional reactivity and force control: the influence of behavioral inhibitionStephen A Coombes
Department of Kinesiology and Nutrition, University of Illinois at Chicago, 1919 West Taylor, 650 AHSB, Chicago, IL 60612, USA
Hum Mov Sci 30:1052-61. 2011..Together these findings extend the premise of action readiness to demonstrate that dispositional differences in behavioral inhibition interact with emotional state to alter force production...
Spatiotemporal dynamics of brain activity during the transition from visually guided to memory-guided force controlCynthia Poon
Department of Kinesiology and Nutrition, University of Illinois at Chicago, Chicago, IL, USA
J Neurophysiol 108:1335-48. 2012..The findings show that subjects rely on sensorimotor memory processes involving left ventral premotor cortex and ventral prefrontal cortex after the immediate transition from visually guided to memory-guided force control...
Predicting grip force amplitude involves circuits in the anterior basal gangliaPooja Wasson
Department of Kinesiology and Nutrition, University of Illinois at Chicago, Chicago, IL, USA
Neuroimage 49:3230-8. 2010..Further, the results provide additional support for the planning and parameterization model of the basal ganglia by demonstrating that specific anterior nuclei of the basal ganglia are involved in planning grip force...
Segregated and overlapping neural circuits exist for the production of static and dynamic precision grip forceKristina A Neely
Department of Kinesiology and Nutrition, University of Illinois at Chicago, Chicago, IL 60612, USA
Hum Brain Mapp 34:698-712. 2013..These findings provide the first neuroimaging evidence supporting a lateralized pattern of brain activity for the production of static and dynamic precision grip force...
