BIOPAC Citations | 2023 in Review

BIOPAC was cited in over 2,400 studies this year, coming to a total of over 50,000 all time! We love seeing how researchers use our tools in their work, and there were a lot of interesting studies this past year. Here is a recap of some of the publications we’ve seen this year…

How Long Is Long Enough? Controlling for Acute Caffeine Intake in Cardiovascular Research. Brain Sciences, 13(2), 224. Grant, S. S., Kim, K., & Friedman, B. H. (2023).

This study hypothesized that the effects of caffeine on heart reactivity, specifically in coffee, would wear off after six hours. Researchers had participants perform hand cold pressor and memory tasks before having coffee, thirty minutes after having coffee, and six hours (caffeine’s average half-life) after having coffee. They utilized a BIOPAC respiratory effort transducer belt, noninvasive blood pressure system, and electrobioimpedance amplifier to record their data.

Differential Momentary Reports of Stress and Affect Associated With Alcohol Consumption in Middle-Aged Versus Younger Adults. Substance Use & Misuse, 1-10. Peterson-Sockwell, H., Rejeski, W. J., Fanning, J., Porges, S. W., Heilman, K. J., Laurienti, P. J., & Gauvin, L. (2023).

Researchers studied stress as a motivator for consuming alcohol. They recorded the differences in stress and affect between younger adults and middle-aged adults with a wireless ECG setup through a BIOPAC BioNomadix System.

Effects of Chair-Based Fidgeting and Age on Prefrontal Brain Activity and Cognitive Performance. Journal of Speech-Language & Hearing Disorders (언어치료연구), 32(1), 91-98. Hwang, J., Kim, I. S., Madasu, C., & Lee, C. (2023).

In this study, researchers recorded prefrontal cortex activity in both young and older adults when sitting at a conventional workstation compared to sitting at a workstation equipped with an under-the-table leg-fidgeting bar. BIOPAC’s fNIRS system was used to record the prefrontal cortex activity while participants completed neurocognitive tests.

The Impact of Lifestyle Factors on Heart Rate Variability During the Transition from High School to College. In International Journal of Exercise Science: Conference Proceedings (Vol. 16, No. 2, p. 105). Lipsman, A., Higgins, S., Nepocatych, S., & Weaver, M. (2023).

This study aimed to determine whether there was a correlation between the transition to college and change in cardiovascular health. They examined how change of sedentary behavior (SB) related to moderate to vigorous physical activity (MVPA), dietary habits, and stress would affect HRV in college students. Researchers performed baseline assessments on high school seniors and followed up a year later, during the second semester of college to record the change. HRV was assessed based on ECG recordings, obtained with a BIOPAC ECG amplifier.

Using virtual reality to study fear and extinction in children and adolescents. Translational Methods for PTSD Research (pp. 37-49). New York, NY: Springer US. Marusak, H. A., Peters, C., & Rabinak, C. A. (2023).

Researchers conducted this study to establish a way to examine fear and extinction in children and adolescents. Fear and extinction are important measures for studying fear-based disorders, but age-appropriate tools are required for younger populations, when many fear-based disorders start. Researchers used virtual reality paired with BIOPAC systems and software in order to record their findings.
