A Study on Brain-Computer Interface Using Transient Visual Evoked Potentials
brain-computer interface (BCI) visual evoked potentials (VEPs) steady-state VEPs (SSVEPs) transient VEPs
2009/6/1
It is necessary for brain-computer interfaces (BCIs) to be non-offensive devices for daily use to improve the quality of life of users, especially for the motor disabled. Some BCIs which are based on ...
Optical and electrical recording of neural activity evoked by graded contrast visual stimulus
Optical and electrical recording neural activity graded contrast visual stimulus
2010/2/25
In this study, we present the measuring system; the results consist in concurrent recordings of hemodynamic changes and evoked potential responses emerging from different contrast levels of a patterne...
TRANSIENT SUDDEN BILATERAL VISUAL LOSS AFTER ORTHOTOPIC HEART TRANSPLANTATION: A CASE REPORT
Sudden visual loss heart transplantation transient bilateral visual loss
2010/2/1
Post cardiac surgery ophthalmic complications are uncommon, and sudden visual loss is one of the most important ophthalmic problems in these patients. We report a 54-year-old woman that suffered trans...
Dynamic Sensor-Based Control of Robots with Visual Feedback
Dynamic Sensor Visual Feedback Robots
2009/12/24
Abstruct-Sensor-based robot control may be viewed as a hierarchical
structure with multiple observers. Actuator, feuture-bused, and recognition
observers provide the basis for multilevel feedback co...
