Controlled Clinical Trial
Multimodal assessment of primary motor cortex integrity following sport concussion in asymptomatic athletes.
Recent studies have shown, in asymptomatic concussed athletes, metabolic disruption in the primary motor cortex (M1) and abnormal intracortical inhibition lasting for more than six months. The present study aims to assess if these neurochemical and neurophysiological alterations are persistent and linked to M1 cortical thickness. ⋯ The present study highlights the importance of multimodal assesments of the impacts of sport concussions.

In a previous study we proposed a robust method for automatic seizure detection in scalp EEG recordings. The goal of the current study was to validate an improved algorithm in a much larger group of patients in order to show its general applicability in clinical routine. ⋯ The algorithm is a valuable tool for fast and effective screening of long-term scalp EEG recordings.

Neuromagnetic beta and gamma oscillations in the somatosensory cortex after music training in healthy older adults and a chronic stroke patient.
Extensive rehabilitation training can lead to functional improvement even years after a stroke. Although neuronal plasticity is considered as a main origin of such ameliorations, specific subtending mechanisms need further investigation. Our aim was to obtain objective neuromagnetic measures sensitive to brain reorganizations induced by a music-supported training. ⋯ The proposed protocol can be used for monitoring changes in neuronal organization during training and will improve the understanding of the brain mechanisms underlying rehabilitation.

Temporal evolution of event-related desynchronization in acute stroke: a pilot study.
Assessment of event-related desynchronization (ERD) may assist in predicting recovery from stroke and rehabilitation, for instance in BCI applications. Here, we explore the temporal evolution of ERD during stroke recovery. ⋯ Improved understanding of ERD in acute stroke may assist in prognostication and rehabilitation.

Controlled Clinical Trial
Lack of visual evoked potentials amplitude decrement during prolonged reversal and motion stimulation in migraineurs.
We evaluated response decrement during a short time repetitive low and high contrast reversal and low contrast motion stimulation in controls and migraineurs. ⋯ Low contrast and motion-onset stimuli in short time decrement assessment did not increase the test sensitivity.
