This PRO Lesson describes basic reflex and reaction time (visual stimulus) exercises and details hardware and software setup of the BSL Lessons System to record reaction time to auditory stimulus. All data collection and analysis is done via the BIOPAC MP3x data acquisition unit and the Biopac Student Lab Lessons software.
Measure reflex response of the femoral, medial popliteal, musculocutaneous and radial nerves.
Measure reaction time to visual stimulus.
Observe the effects of learning and physiological processes on reaction times of auditory stimulus.
Compare reaction times with two presentation schedules: fixed intervals and pseudo-random intervals of auditory stimulus.
Design an experiment to determine factors that affect reaction time and indicate specifically where in the nervous system sequence a factor had its effect.
Tasks Performed by the Student
perform muscle reflex exercises,
visual stimulus exercises, and
auditory stimulus exercises.
Add event markers throughout the recording.
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.

Why do we so easily believe Fake News? 68% of Americans find their news through social media, and the prevalence of incomplete or deceptive news stories dubbed “fake news” has wormed its way into the fabric of modern-day media. In an effort to study how social media based news is perceived, this study measured physiological […]
Comparing Diaphragm Tissue Between Healthy and Ill Patients The human diaphragm is one of the primary muscles used in respiration, contracting and expanding to control breathing. To measure how much diaphragms move for critically ill patients (in an Intensive Care Unit) compared to diaphragms in a healthy subject, patients at “Papageorgiou” General Hospital in Thessaloniki, […]
