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.

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.
