Complexity vs. unity in unilateral spatial neglect
2017, Revue NeurologiqueCitation Excerpt :Motor neglect should be distinguished from motor disorders that affect movements of the ipsilesional arm directed towards the neglected space, such as slowness of motor initiation or “directional hypokinesia” [41–43], delayed motor execution or “directional bradykinesia” [44], and decreased movement amplitude or “directional hypometria”, while also involving ocular saccades [45,46]. The anatomical lesion correlates of motor neglect are the prefrontal and parietal cortex [38,45,47,48], motor and premotor association areas [38,48,49], cingulum, putamen, internal capsule and thalamus [39,40,48–51], with sparing in all cases of the primary sensorimotor cortex [38]. Unlike sensory neglect, motor neglect cannot be explained by either contralesional bias of spatial attention orientation or impaired building and/or exploration deficits of mental spatial representations.
Semiology of neglect: An update
2017, Annals of Physical and Rehabilitation MedicineCitation Excerpt :The anatomical lesion correlates of MN are still being debated. MN was reported after lesions of the prefrontal and parietal cortex [50,56–59], subcortical lesions (putamen, internal capsule, thalamus) [51,52,59–62], lesions of the motor and premotor association areas [50,58,59,63] but sparing in all cases the primary sensorimotor cortex [50]. Finally, in 4 patients with MN, including 3 with associated VN, the only common brain structure damaged was the cingulum, which is a bundle of fibers involved in motor initiation and connected to all limbic structures involved in motivational aspects of action [55].
Changes in cognition and health-related quality of life with unilateral thalamotomy for Parkinsonian tremor
2009, Journal of Clinical NeuroscienceCitation Excerpt :Right-sided operations have generally been associated with fewer residual deficits,1,2,7 though visuo-perceptual,9 motor coordination and integration problems3,10 have been described. Visual hemi-inattention has been demonstrated in left-sided and right-sided operations, with the former more impaired.10 Difficulties with earlier studies included variability in assessment measures, and in the size and specificity of the surgical lesions produced.
