[A multifunctional microcomputer pattern-stimulator]

Area of Science:

• Biomedical Engineering
• Neuroscience
• Ophthalmology

Background:

• Developing advanced visual stimulators is crucial for understanding retinal function and visual processing.
• Existing systems may lack the flexibility for multi-pattern generation or precise control over stimulation parameters.

Purpose of the Study:

• To describe the hardware and software design of an automated multi-functional pattern-stimulator.
• To enable high-resolution retinal image stimulation with versatile control options.

Main Methods:

• Design of a pattern-stimulator based on the KR1810BM86A microprocessor.
• Implementation of remote control via RS-232C channel and autonomous operation.
• Development of multi-task real-time operating system software for pattern generation.

Main Results:

• The stimulator can form multi-pattern stimulation images with high angular resolution (one retinal element).
• It supports various stimulation types across a wide range of intensities and colors.
• The system allows for both remote and autonomous control modes.

Conclusions:

• The developed automated pattern-stimulator provides a flexible and precise tool for visual neuroscience research.
• Its capabilities facilitate detailed investigation of the eye retina's response to complex visual stimuli.
