Effects of unilateral motor cortex lesion on ipsilesional hand's reach and grasp performance in monkeys: relationship with recovery in the contralesional hand.
Manual dexterity, a prerogative of primates, is under the control of the corticospinal (CS) tract. Because 90-95% of CS axons decussate, it is assumed that this control is exerted essentially on the contralateral hand. Consistently, unilateral lesion of the hand representation in the motor cortex is followed by a complete loss of dexterity of the contralesional hand. During the months following...
متن کاملThe Effect of Lesion Size on the Organization of the Ipsilesional and Contralesional Motor Cortex
Recovery of hand function following lesions in the primary motor cortex (M1) is associated with a reorganization of premotor areas in the ipsilesional hemisphere, and this reorganization depends on the size of the lesion. It is not clear how lesion size affects motor representations in the contralesional hemisphere and how the effects in the 2 hemispheres compare. Our goal was to study how lesi...
متن کاملThe effect of lesion size on cortical reorganization in the ipsi and contralesional hemispheres
motrice la plus influencée dans le cortex contralésionnel. ABSTRACT While our understanding of ipsilesional plasticity and its role in recovery of hand function following ischemic stroke has increased dramatically, the reorganization of the contralesional motor cortex and its effect on recovery remain unclear. Currently published studies offer contradictory views on the role of contralesional m...
متن کاملEffects of High-Frequency Repetitive Transcranial Magnetic Stimulation on Motor Functions in Patients with Subcortical Stroke
Background: Motor function impairment occurs in approximately two-thirds of patients with subcortical stroke. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique for modulating cortical excitability. Objectives: The present study was designed for assessing the efficacy of high-frequency rTMS (5 Hz) on ipsilesional primary motor cortex in patients with subcortical stro...
متن کاملUnilateral ischemic sensorimotor cortical damage induces contralesional synaptogenesis and enhances skilled reaching with the ipsilateral forelimb in adult male rats.
Unilateral damage to the forelimb representation area of the sensorimotor cortex (SMC) results in a compensatory reliance on the unimpaired (ipsilateral to the lesion) forelimb as well as reorganization of neuronal structure and connectivity in the contralateral motor cortex. Recently, male rats with unilateral electrolytic SMC lesions were found to have enhanced skilled reaching performance wi...
