Motor imagery in neurological rehabilitation
… have been observed to attain greater impact. Motor imagery is a promising intervention for use in rehabilitation as it can be used to safely increase treatment dose at low cost. However, motor imagery is a complex intervention and there is limited evidence on the optimal content and delivery …

Motor Imagery Based Brain Computer Interfaces
… with external devices using their brain signals. Motor imagery classification is one such area in BCI systems where the goal is to detect and classify the motor related intentions of humans using their brain signals. The desired accuracy of BCI systems cannot be achieved without the preprocessing …

Motor imagery classification using sparse representation of EEG signals
… and potentially back to the body. Classifying motor imagery brain signals where the signals are obtained based on imagined movement of the limbs is a major, yet very challenging, step in developing Brain Computer Interfaces (BCIs). Of primary importance is to use less data and computationally …

Neural Mechanisms of Motor Imagery and Training-Induced Plasticity: Hypnotizability Relevance to Microgravity Adaptation
… alteration regarding sensory information, sensorimotor integration, and interoceptive and vestibular feedback disruption. Such alterations impair postural control, spatial orientation, and fine motor skills. Motor imagery (MI), defined as the mental simulation of movement without overt execution, …

The effectiveness of graded motor imagery for reducing phantom limb pain and disability in amputees
… in people who have undergone amputations. Graded motor imagery (GMI) is a cortical mechanisms-based intervention which aims to reduce PLP using a graded sequence of strategies including left/right judgements, imagined movements and mirror therapy. The aim of this thesis was to investigate whether …

The effects of mental training on brain computer interface performance with distractions
… use these techniques. Both groups were given a motor imagery based BCI protocol, a P300 speller BCI, a verbal learning task, and an N-back test. No significant difference in performance was found between meditation and control groups. Our research does suggest however, significant differences …

Investigating the Functional and Structural Neural Correlates Associated With Dance Expertise
… maps of dancers and controls engaged in motor imagery of dance movements were compared. Controls were found to show greater activity in numerous regions relative to dancers, including in the superior frontal gyrus, hippocampus, and cerebellum. Anatomically, dancers exhibited greater …

Brain-Computer Interface Fatigue in Children: Mechanisms and Impact
… aged 7-16 years participated in three sessions: motor imagery-BCI, P300-BCI, and film viewing (control). Self- reported fatigue and resting-state EEG alpha band power significantly increased across all sessions (p < 0.001; p = 0.047 respectively). These two measures of fatigue were uncorrelated …

Sound-production Related Cognitive Tasks for Onset Detection in Self-Paced Brain-Computer Interfaces
… a new message arrived by executing the Sound Imagery (SI) onset detection task in real-life scenarios (e.g. watching video, reading text). The SI task was chosen as an onset task because of its advantages over other tasks: 1) Intuitiveness. 2) Beneficial for people with motor disabilities. 3) …
