This study introduces a computer system for collecting and analyzing Visual Evoked Potentials (VEPs). The system aids in diagnosing various diseases using VEP data analysis.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Computer Science

Background:

  • Visual Evoked Potentials (VEPs) are crucial for assessing visual pathway function.
  • Accurate data collection and analysis are essential for reliable VEP interpretation.
  • Existing methods may lack the integration and analytical capabilities for comprehensive VEP diagnostics.

Purpose of the Study:

  • To develop and describe an interactive, PC-based computer-controlled system for VEP data acquisition and analysis.
  • To enable precise generation of visual stimuli and digitization of VEP waveforms.
  • To provide advanced analysis tools for VEPs, facilitating their use in disease diagnosis.

Main Methods:

  • Utilized a PC-based system with an Enhanced Graphics Adaptor (EGA) for visual stimulus generation on a high-resolution monitor.
