Repetitive bilateral arm training and motor cortex activation in chronic stroke: a randomized controlled trial. (2004, background): “Serial functional imaging studies show that contralesional recruitment is demonstrable early after stroke and then declines as spontaneous recovery progresses.(8,26,29-31) The functional relevance of contralesional recruitment is unclear.”
Neural correlates of outcome after stroke: a cross-sectional fMRI study (2003, background): “Subsequently, two studies in which patients were scanned early after stroke and then again some months later demonstrated an overall reduction of much of this task-related activation (Marshall et al., 2000; Calautti et al., 2001).”
Correlation between motor improvements and altered fMRI activity after rehabilitative therapy. (2002, background): “There is growing evidence from human brain imaging studies that movement of an affected limb with partial recovery after a stroke is associated with altered activity in motor cortical regions (Chollet et al., 1991; Weiller et al., 1992; Cao et al., 1994, 1998; Caramia et al., 1996; Cicinelli et al.,”
Repairing the human brain after stroke: I. Mechanisms of spontaneous recovery (2008, background): “The second panel summarizes the time course of functional magnetic resonance imaging (fMRI) sensorimotor cortex activation, which is similar in animals(68,69) and humans.(70,73,83) Behaviorally (top), most spontaneous recovery occurs in the early weeks after stroke.”
Functional potential in chronic stroke patients depends on corticospinal tract integrity. (2006, background): “Those patients who make meaningful gains in motor function with physical therapy exhibit a return towards contralateral cortical control of the affected upper limb, with an increase in ipsilesional cortical activity (Marshall et al., 2000; Carey et al., 2002; Johansen-Berg et al., 2002a; Nelles, 200”
Neural correlates of motor recovery after stroke: a longitudinal fMRI study (2003, background): “…brain activation across sessions for task A and task B. Previous attempts at characterizing longitudinal changes have often done so in terms of shifts in task-related activation between contralesional and ipsilesional sensorimotor and premotor cortices (Marshall et al., 2000; Feydy et al., 2002).”
Modulating cortical connectivity in stroke patients by rTMS assessed with fMRI and dynamic causal modeling (2010, neutral): “Patients with better functional outcome, however, exhibit a progressive lateralization of neural activation towards the ipsilesional hemisphere (Carey et al., 2002; Marshall et al., 2000; Nelles, 2004; Ward et al., 2003).”
Evidence-based guidelines on the therapeutic use of transcranial direct current stimulation (tDCS). (2017, background): “As mentioned above, the classical concept of interhemispheric competitive rivalry supports the objective of decreasing the excitability of the contralesional motor cortex and its ability to further reduce the neural activities in the lesioned hemisphere (Marshall et al., 2000; Ward et al., 2003; Mur”
Dynamic intra- and interhemispheric interactions during unilateral and bilateral hand movements assessed with fMRI and DCM (2008, background): “In stroke patients, neuroimaging studies showed increased activity of M1 of the unaffected hemisphere during movements of the paretic hand (Carey et al., 2002; Marshall et al., 2000; Ward and Cohen, 2004).”
