Interhemispheric interactions between trunk muscle representations of the primary motor cortex The mechanisms involved in the bilateral coordination of axial muscles of the trunk during unilateral arm movement are poorly understood. We thus investigated the nature of interhemispheric (between the two hemispheres of the brain) interactions in axial
H-reflex modulation preceding changes in soleus EMG activity during balance perturbation When balance is compromised, postural strategies are induced to quickly recover from the perturbation and to regain balance. However, neuronal mechanisms underlying these strategies are not fully understood. In this article, we assessed the amplitude of the Hoffmann’s
Alteration of H-reflex modulation underlies impaired postural responses in individuals with incomplete spinal cord injury Individuals with incomplete spinal cord injury (iSCI) are at higher risk of falling, even after intensive functional rehabilitation (Brotherton et al., 2007; Amatachaya et al., 2011). This risk of falling is due to decreased
Assessment of vestibulocortical interactions during standing in healthy subjects The vestibular system is essential to produce adequate postural responses enabling voluntary movement. However, it is still unknown how exactly the vestibular system influences corticospinal output during postural tasks. Here, we examined the modulation exerted by the vestibular system on
