Pulse Oximetry and COPD: A recent study performed by Salim S. Al-Ani compared Pulse Oximetry levels in healthy adults and in a sample of individuals with severe chronic obstructive pulmonary disease (COPD) in order to better understand the relation among PO, age, and gender in healthy adults. Salim used a BIOPAC MP150 with the OXY100E, RSP100C, […]

Brain Connectivity and Human Responses to Music: While it has been proven that people find music aesthetically appealing because of neural circuitry, it is unclear why individuals received different levels of enjoyment to different types of music. Researchers from Wesleyan University used a combination of survey data and behavioral and psychophysiological measures to try and understand […]

Brain-Body Interactions: While it is generally agreed that the brain influences the physiological condition of the body, it is unclear what areas of the brain affect the body differently. Christine C. Guo, et al showed that the behavioral variant of frontotemporal dementia (bvFTD) is associated with reduced baseline cardiac vagal tone and that it correlates […]

Personal Identification: Researchers from Yonsei University recently performed a study testing the viability of using ECG signals for individual identification, much like a password or key. Their study investigated experiments that recorded ECG after exercise and estimated the recognition potential of these signals. ECG was measured from subjects using the BIOPAC MP150 data acquisition system […]

Energy Drinks and Blood Pressure: Energy drinks are used to increase energy in the body through various physiologic means. Bashir Uddin, Mohiuddin Ahmad, and Mohd Abdur Rashid measured blood pressure changes as a result of energy drink consumption. Twelve adult male participants lay down after each consumed an energy drink. Their ECGs were then  recorded for […]

Facial EMG vs Automatic Facial Coding: Arvid Kappas, Dennis Küster, Pasquale Dente, Christina Basedow tested whether facial EMG automatic coding of facial movement provided a reliable assessment of facial activity. The researchers tested 23 participants learning the association of Japanese characters and sounds in interaction. Subjects’ EDA and EMG data was recorded using BIOPAC EDA100C […]

SET and Fibromyalgia: A research group created a process called “Systolic Extinction Training” (SET) which can reset the abnormal relationship between blood pressure (BP) and pain in fibromyalgia and chronic pain patients. To test the validity of their process, they used a BIOPAC MP150 system with ECG100C amplifier module while AcqKnowledge software stored and calculated […]

Psychophysiological Indicators for Substance Abuse in Preschoolers: Children’s development of emotional regulation is seen as an extremely crucial part in their development of social behavior. Researchers from the University of Oregon hypothesized that children whom have faced high levels of adversity, and would thus have low emotional regulation, would help identify physiological markers that could indicate […]

Virtual Reality Muscle Training in Stroke Patients: Muscle weakening of the lower extremities has a significant correlation with loss of balance and walking ability in stroke patients. Researchers at Sehan University studied the effect of a virtual reality-based eccentric training program on lower extremity muscle activation and balance for rehabilitation of stroke patients. BIOPAC’s EMG100C surface […]

 Acupuncture and Rheumatoid Arthritis: Researchers from University of Porto aimed to get results of the effect of acupuncture, as a treatment to Rheumatoid arthritis (RA) condition, and examine the benefits on the strength and nerve conduction improvements. To measure the nerve conduction and strength they used BIOPAC UIM100 module connected to a BIOPAC MP system with a […]
