In the Systemic Blood Pressure lesson, students use the auscultatory technique to record arterial blood pressure.
Students record blood pressure using a cuff, pump and pressure gauge, Korotkoff sounds using a microphone, and ECG using Lead II. The system will display cuff pressure, Korotkoff sounds and ECG for easy determination of systolic blood pressure. Students view the Korotkoff sounds and listen to them with a stethoscope or headphones.* They will perform a task designed to change their blood pressure.
* BSL 4.0.2 and above includes a headphone output option for monitoring stethoscope sounds through OUT1/OUT1A/40HP via the MP Analog Output or headphone jack.
To use an Auscultatory method for an indirect determination of systemic arterial and diastolic blood pressure and to correlate the appearance and disappearance of vascular sound with systolic and diastolic pressure respectively.
To measure, record and compare systemic arterial blood pressure in the right arm and the left arm of the same subject under identical conditions.
To measure, record and compare systemic arterial blood pressures in the same subjects under different experimental conditions of rest and exercise.
To compute, record and compare pulse pressure and mean arterial pressure under different experimental conditions of rest and exercise.
To correlate the Korotkoff sounds to the mechanic events of the cardiac cycle.
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.

Many studies use hand dynamometry to objectively quantify exerted effort during experiments most commonly related to the study of motivation.
We’ll focus on this topic and go over everything you need to know to record dynamometry data in the MRI or in the lab. Topics include
– Calibrating for maximum voluntary contraction (MVC)
– Real-time access to the dynamometer signal by third-party applications
– How researchers have used this equipment
– Creating a visual task that gives feedback on exerted effort as well as rewards to the participant

Discovering and understanding what motivates humans to produce better results has intrigued many researchers. Many researchers have explored the psychophysiological processes that drive our behavior. Here are some recent studies that have used BIOPAC systems to research motivation… Motivation and Pleasure Deficits Undermine the Benefits of Social Affiliation in Psychosis. Blanchard, J. J., Smith, J. […]
Eye tracking technology has come a long way and has enabled researchers to conduct mobile experiments and track participants in real world scenarios. These featured studies demonstrate some of the use cases for mobile eye tracking technology. Here are some recent studies that have used BIOPAC systems for eye tracking research… Drivers’ gaze patterns when resuming […]
