On the use of convolutional neural networks and augmented CSP features for multi-class motor imagery of EEG signals classification.

Learning the deep structures and unknown correlations is important for the detection of motor imagery of EEG signals (MI-EEG). This study investigates the use of convolutional neural networks (CNNs) for the classification of multi-class MI-EEG signals. Augmented common spatial pattern (ACSP) features are generated based on pair-wise projection matrices, which covers various frequency ranges. We pr...

Robust supervised segmentation of neuropathology whole-slide microscopy images.

Alzheimer's disease is characterized by brain pathological aggregates such as Aβ plaques and neurofibrillary tangles which trigger neuroinflammation and participate to neuronal loss. Quantification of these pathological markers on histological sections is widely performed to study the disease and to evaluate new therapies. However, segmentation of neuropathology images presents difficulties inhere...

Gastrocnemius myoelectric control of a robotic hip exoskeleton.

In this paper we present a novel EMG-based assistive control strategy for lower-limb exoskeletons. An active pelvis orthosis (APO) generates torque pr...

Compliant gait assistance triggered by user intention.

An automatic gait initialization strategy based on user intention sensing in the context of rehabilitation with a lower-limb wearable robot is propose...

Assessing neuro-motor recovery in a stroke survivor with high-resolution EEG, robotics and Virtual Reality.

One post-stroke patient underwent neuro-motor rehabilitation of one upper limb with a novel system combining a passive robotic device, Virtual Reality...

Comparison between the therapeutic effects of robotic-assisted locomotor training and an anti-spastic medication on spasticity.

We studied the effects of robotic-assisted locomotor (LOKOMAT) training or an anti-spastic medication (tizanidine) on neuromuscular abnormality associ...

Neural network based forward prediction of bladder pressure using pudendal nerve electrical activity.

Individuals with spinal cord injury or neurological disorders have problems in urinary bladder storage and in voiding function. In these people, the d...

There exists a 6-8 hour window of opportunity for the treatment of perinatal Hypoxic-Ischemic Encephalopathy (HIE) following the original insult after...

Seizure detection using regression tree based feature selection and polynomial SVM classification.

This paper presents a novel patient-specific algorithm for detection of seizures in epileptic patients with low hardware complexity and low power cons...

Convergent Cross Mapping: Basic concept, influence of estimation parameters and practical application.

In neuroscience, data are typically generated from neural network activity. Complex interactions between measured time series are involved, and nothin...

Shifting the balance of human standing: Inter-limb coordination for the control of a robotic balance simulation.

Learning to maintain standing balance in the presence of a paretic limb is an important recovery process for many stroke survivors. In this study, we ...

Transoral robotic surgery for base of tongue neoplasms.

Surgery to the base of tongue (BOT) in the presence of neoplasm is a challenging topic for head and neck surgeons. This area is difficult to access an...
