Recent progress with spinal cord injured (SCI) patients indicates that with training they can recover some locomotor ability. Here we addressed the question of whether locomotor responses developed with training depend on re-activation of the normal motor patterns or whether they depend on learning new motor patterns. To this end we recorded detailed(More)
In the present study, we used electrophysiological, biochemical, and confocal microscopy techniques, to investigate the functional role of transient receptor potential vanilloid type 1 (TRPV1) and cannabinoid type 1 receptors (CB1-R) in the substantia nigra pars compacta (SNpc) and their stimulation by the endocannabinoid N-arachidonoyl-dopamine (NADA).(More)
OBJECTIVE Motor imagery (MI) is assumed to enhance poststroke motor recovery, yet its benefits are debatable. Brain-computer interfaces (BCIs) can provide instantaneous and quantitative measure of cerebral functions modulated by MI. The efficacy of BCI-monitored MI practice as add-on intervention to usual rehabilitation care was evaluated in a randomized(More)
The cerebellar role in non-motor functions is supported by the clinical finding that lesions confined to cerebellum produce the cerebellar cognitive affective syndrome. Nevertheless, there is no consensus regarding the overall cerebellar contribution to cognition. Among other reasons, this deficiency might be attributed to the small sample sizes and narrow(More)
Several recent studies support the view that the cerebellum's contribution to sensory processing is not limited to movement regulation. In a previous paper (Restuccia D, Valeriani M, Barba C, Le Pera D, Capecci M, Filippini V, Molinari M. Functional changes of the primary somatosensory cortex in patients with unilateral cerebellar lesions. Brain 2001; 124:(More)
In recent years, network analyses have been used to evaluate brain reorganization following stroke. However, many studies have often focused on single topological scales, leading to an incomplete model of how focal brain lesions affect multiple network properties simultaneously and how changes on smaller scales influence those on larger scales. In an(More)
Sensorimotor synchronization (SMS) is the rhythmic synchronization between a timed sensory stimulus and a motor response. This rather simple function requires complex cerebral processing whose basic mechanisms are far from clear. The importance of SMS is related to its hypothesized relevance in motor recovery following brain lesions. This is witnessed by(More)
The cerebellar contribution to motor entrainment through rhythmic auditory stimuli was analyzed by comparing rhythmic motor responses in subjects with cerebellar pathologies and in healthy controls. Eleven patients with cerebellar lesions and eight healthy subjects tapped in synchrony with an auditory rhythmic stimulus using a hand-held pencil-shaped(More)
Increasing evidence suggests that the basic foundations of the self lie in the brain systems that represent the body. Specific sensorimotor stimulation has been shown to alter the bodily self. However, little is known about how disconnection of the brain from the body affects the phenomenological sense of the body and the self. Spinal cord injury (SCI)(More)
Neuroprosthetic technology and robotic exoskeletons are being developed to facilitate stepping, reduce muscle efforts, and promote motor recovery. Nevertheless, the guidance forces of an exoskeleton may influence the sensory inputs, sensorimotor interactions and resulting muscle activity patterns during stepping. The aim of this study was to report the(More)
