The rapid increase in the number of older adults around the world is accelerating research in applications to support age-related conditions, such as brain–computer interface (BCI) applications for post-stroke neurorehabilitation. The signal processing algorithms for electroencephalogram (EEG) and other physiological signals that are currently used in BCI have been developed on data from much younger populations. It is unclear how age-related changes may affect the EEG signal and therefore the u...

We proposed a multi-class tactile brain–computer interface that utilizes stimulus-induced oscillatory dynamics. It was hypothesized that somatosensory attention can modulate tactile-induced oscillation changes, which can decode different sensation attention tasks. Subjects performed four tactile attention tasks, prompted by cues presented in random order and while both wrists were simultaneously stimulated: 1) selective sensation on left hand (SS-L); 2) selective sensation on right hand (SS-R); ...

Introduction Pain can affect people regardless of age, gender or ethnicity. Chronic central neuropathic pain (CCNP) is a debilitating condition that affects populations such as stroke survivors, amputees, spinal cord injury patients and patients with multiple sclerosis, with prevalence rates between 30% and 80%. This condition can be caused by a lesion or disease affecting the somatosensory system. CCNP is notoriously drug resistant, and few effective CCNP treatment or management strategies exis...

Brain-computer interface (BCI) provides an alternative way for lock in patients to interact with the environment solely based on neural activity. The drawback with independent BCIs is their lack in the number of commands – usually only two are available. This provides great challenges to the BCI’s usefulness and applicability in real-life scenarios. A potential avenue to increasing the number of independent BCI commands is through modulating brain activity with music, in regions as the orbitofro...

In this work, the variation of the waveform of the movement related cortical potential (MRCP) was investigated in a real-time neurofeedback study, in which the spontaneous slow cortical potential (SCP) within the same frequency band as MRCP ([0.05 3] Hz) was provided as feedback to the subjects. Experiments have shown that the background SCP activity has a strong influence on the waveform of the self-paced MRCP. Negative potential SCP has been shown to increase the negative peak of the MRCP wave...

In this study, cortical oscillatory dynamics with respect to tactile selective sensation tasks were investigated. Subjects were required to perform three tactile attention tasks, prompted by cues presented in random order and while both wrists were simultaneously stimulated: 1) selective sensation of the left hand (SS-L), 2) selective sensation of the right hand (SS-R), 3) bilateral selective sensation (SS-B). Even-related (de)synchronization (ERD/ERS) analysis revealed a clear contralateral act...

This work proposes a Common Spatial Pattern with Polarity Check (CSPPC) to facilitate Movement Related Cortical Potential (MRCP) detection. The algorithm was compared with the Locality Preserving Projection (LPP) algorithm in the context of detecting foot dorsiflexion within a group of thirteen subjects. It has been shown that CSPPC achieved a significantly reduced delay latency compared to LPP (−25.9±190.7 ms vs. 204.6±123.7 ms), which had a similar detection accuracy (true positive rate: 73.6±...
