Echium Oil vs. Fish Oil Food and Nutrition researchers have recently taken a look at the health benefits of stearidonic acid (SDA), an omega-3 fatty acid. It had been suggested that SDA has comparable effects on human health to those achieved by intake of fish oil. Rats were tested for blood pressure and electrocardiogram changes […]
BIOPAC Systems, Inc. crossed yet another milestone with its solar power—the company has saved more than 615,000 pounds of CO2 emissions by generating 410,000 kilowatt hours (KWH) since installing solar roof tiles in January 2007. Solar power covers 35-50% of the company’s power needs, depending on the season. In addition to solar roof tiles, the company […]
Entropy Change in Human Physiological System Researchers at the NASA Human Engineering laboratory recently took a thermodynamic approach to human physiology to make inferences about internal entropic changes in response to cognitive stress. This novel approach utilized Maxwell relations, which are equations derived through mathematical manipulation of thermodynamic variables, to use physiological measures to calculate a […]
Here’s a fun application we haven’t heard of yet—using BIOPAC to test relationship compatibility! BIOPAC equipment was recently featured on ABC’s The Bachelor. In the episode, a “matchmaking test” was performed between the bachelor and several of his potential female companions to observe physiological changes that occurred while in close, one-on-one contact. BioNomadix wireless transmitters can be […]
Political scientist Gregg Murray, Ph.D. recently published a post on Psychology Today regarding electrophysiological cues in highly political individuals. In it, he discusses the inherent biases of those identifying with a certain political party, and underlying physical evidence quantified using electrodermal activity. Murray cites a study performed by Petersen, Giessing and Nielsen in which partisan subjects were hooked up […]
Alan Macy recently gave a TEDx talk in Hong Kong on how the concept of beauty influenced the early origins of electrophysiology. Alan’s talk begins with early conceptions on how to quantify beauty and weaves its meaning with emotional feeling, taste, the galvanic cell, electrophysiology, the telephone, re-tribalization and the global theatre. You can view the […]
The best ways to set up participants to record good data for life science research and teaching labs. – Which electrode? – Which lead? – Do I need Ground (GND)? – Best placement? – Best recording system?
We’re turning on the web cam and showing you LIVE how to best prep participants for a variety of life science signals and measurements.
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
BIOPAC’s just released Introductory ECG Guide addresses fundamental to advanced concerns to optimize electrocardiography data recording and analysis. Topics include: ECG Complex; Electrical and Mechanical Sequence of a Heartbeat; Systole and Diastole; Configurations for Lead I, Lead II, Lead III, 6-lead ECG, 12-lead ECG, precordial leads; Ventricular Late Potentials (VLPs); ECG Measurement Tools; Automated Analysis Routines […]
