Exploring motion VEPs for gaze-independent communication.
Motion visually evoked potentials (mVEPs) have recently been explored as input features for brain-computer interfaces, in particular for the implementation of visual spellers. Due to low contrast and luminance requirements, motion-based intensification is less discomforting to the user than conventional approaches. So far, mVEP spellers were operated in the overt attention mode, wherein eye mov...
متن کاملThe development of hemispheric asymmetry in human motion VEPs
In six healthy adults we examined the sources underlying P1 and N2 of the motion VEP. For this purpose was acquired, in addition to the VEP, MRI images and patterns of regional cerebral blood flow with SPECT for three of the subjects. With the same motion stimulus we also examined the spatial distribution of N2 in children. In both adults and children left and right half-field responses were co...
متن کامل4245 Visual field examination via motion-onset VEPs
Pureose: In a lot of patients an objectivization of visual field defects is needed. The commonly used VEPs (pattern-reversal, pattern-onset/offset) are not helpful because of their considerable amplitude reduction outside the macula. In contrast the motion-onset VEPs that can be obtained beyond the central 40 " of the vtsual field without significant amplitude reduction (Kuba, M. and Kubova, 2....
متن کاملMotion VEPs, stereopsis, and bifoveal fusion in children with strabismus.
PURPOSE The link between nasal-temporal motion asymmetries and anomalous binocular sensory function in infantile esotropia (ET) has led to the idea that visual evoked potential responses to horizontal motion (mVE) is an alternative measure of sensory binocularity to stereopsis. A second hypothesis is that the mVEP response is a marker for bifoveal fusion. The purpose of this study was to direct...
متن کاملMotion-onset VEPs: Characteristics, methods, and diagnostic use
This review article summarises the research on the motion-onset visual evoked potentials (VEPs) and important motion stimulus parameters which have been clarified. For activation of the visual motion processing system and evocation of the motion-onset specific N2 peak (with latency of 160-200ms) from the extra-striate temporo-occipital and/or parietal cortex, the following stimulus parameters c...
