Effects of action observation training on brain network efficency during motor tasks

Event-Related Desynchronization Analysis During Action Observation and Motor Imagery of Transitive Movements

Rehabilitation and motor skill learning approaches based on Action Observation (AO) and Motor Imagery (MI) rely on the assumption that the sensorimotor system is stimulated by AO and MI tasks similarly to the actual execution of a movement. An advantage of AO over MI is that it is less dependent on subject’s imagination ability, and a direct comparison of their effect on cortical activations during complex upper limb movements has been rarely examined. Therefore, in this study we compare sens...

Association Between Variations in Kinematic Indexes of Manual Dexterity and Mu Rhythm Desynchronization Changes After Action Observation and Motor Imagery

The Mirror Neuron System functioning have enabled the development of Action Observation and Motor Imagery (AOMI) as effective approaches to enhance manual dexterity. Improvements in manual dexterity can be quantified using kinematic indexes during the execution of clinical and functional tests, and neurodynamical correlates of such changes may also be investigated through EEG recording. The current study aimed at investigating (1) kinematic and EEG mu rhythm desynchronization changes after an...

Differences in cortical reorganization during visuo-motor tasks executed with the dominant and non-dominant hands

In the present study, we analysed EEG signals acquired during the execution of a visuomotor task with the right and the left hands in a group of young right-handed volunteers. The main aim was to assess differences in brain network organizations supporting movements with the dominant and non-dominant arms with respect to the resting period. Specifically, variations in the power content and network topology were explored in the subjective mu band with respect to a baseline condition. Our resul...
