This BSL PRO Lesson examines the principle of compartmental modeling, which is based on the fact that electrical circuits can describe and simulate neural, biochemical, and biomechanical systems. Gerald Westheimer published the first quantitative saccadic eye movement model in 1954. He examined a 20° saccade recording, and assumed a step controller, to propose this second-order model to characterize eye motion.
Explore Westheimer’s saccadic eye movement model, which represents the eye as a second-order system.
Record eye motion via EOG setup.
Compare recorded EOG to modeled results.
Tasks Performed by the Student
Record the subject with a 20° saccade.
Record the subject with a 40° saccade.
Create the original Westheimer model.
Adjust the model for a 20° saccade and again for a 40° saccade.
Measure actual results and compare to the adjusted model.
The software automates the calibration procedure for the student. There are no knobs and dials to confuse the student.
Graph template files ensure consistent setup for subsequent Subjects or repeated trials—plus, you can easily add your own lesson plan to the onscreen journal.
The lesson will also work as part of a group study.

Studying Cognitive Activity with fNIR! The age-old game of chess is known as a thinking man’s game, where foresight, critical thinking, and strategy are required to become a good chess player, and the terms “genius” or “brilliance” are bestowed upon the chess masters of the world. As such, chess is an excellent cognitive tool to […]
