In this BSL EOG lesson, students record horizontal and vertical eye movement and observe eye fixation and tracking. Students perform a number of tasks that allow them to record the duration of saccades and fixation. The electrooculogram lesson also permits students to record spatial position of eye movements.
Compare eye movement when fixated on a stationary object and tracking objects.
Measure duration of saccades and fixation during reading.
Instructor’s option: Record spatial position of eye movements during visual examination of materials.
Tasks Performed by the Student
BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.
Record horizontal and vertical EOG.
Face their partner.
The partner will hold a pen in front of the subject and the subject will focus on the pen.
The partner will move the pen horizontally and the subject will track the movement.
The partner will move the pen vertically and the subject will track the movement.
The subject will read a passage of text.
The subject will face the monitor and position their eyes to the center of the screen. By moving their eyes they will control the dot on the screen.
Very easy to setup and record the data.
Tools for zooming in to see the saccades.
Great introduction to EOG.
The software automates the calibration procedure for the student. There are no knobs and dials to confuse them.
On-screen commands prompt the students throughout the lesson.
BIOPAC’s Simple Sensors warn students if they plug the wrong device or transducer into the system.
The lesson will also work with different stimuli.
BSL Instructor’s Guide provides lab tips and lesson options.
BSL Answer Guide included.

New series of unshielded 45 cm electrode leads with thin cable; suitable for facial EMG and other areas where lighter, shorter lead cables are required. Use for female Touchproof connectors to pinch clip connectors—connect electrodes to either a C-series amplifier or an MEC. The pinch connectors are light weight and the lead cable tinsel wire […]
The new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
