The Argus II retinal prosthesis has a dissociation between the line of sight of the camera and that of the eye. The image-capturing camera is mounted on the glasses and therefore, eye movements do not influence the visual information sent to the implanted electrodes.
This pilot study aimed at assessing the feasibility and the effectiveness of an electro Electro-tactile Vestibular Substitution System (EVSS) in patients with unilateral vestibular loss under normal and altered somatosensory conditions from the foot and ankle. Four unilateral vestibular-defective patients voluntarily participated in the experiment. They were asked to stand upright as still as possible...
Brain-Machine Interfaces (BMIs) are being researched controlling external devices such as robots and computers by measuring the cranial nerve activity of the operator. The brain activities evoked by visual stimuli have been studied intensively. However, few studies have considered a BMI that uses the brain activities evoked by auditory stimuli. This study investigated whether a person's direction...
This paper presents advanced signal processing algorithms to quantify brain connectivity with high temporal resolution using the electroencephalogram (EEG). The experimental paradigm exploits the visual cortex response to flickering images at a given frequency. The envelope of the EEG at the flickering frequency collected by 128 electrodes over the head quantifies the communication amongst the brain...
Normal healthy subjects and AMD patients were recorded using 64 EEG channels with a computer based acquisition systems using a pattern-pulse mfVEP. A correctly sized head cap (10/20 layout), was placed over the subjects’ head. The Fpz electrode holder was placed directly on the 10% nasion-inion mark. The data are simultaneously sampled at 256 Hz per channel, and collected using the ActiveTwo BioSemi...
