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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Recent physiological studies feature BIOPAC’s Wireless BioNomadix Data Recorders Using Metronomes and Rhythmic stimulation to help people with Parkinson’s disease walk For those living with Parkinson’s disease, even simple tasks can take too long to accomplish properly, such as crossing a room or picking up an object. In this study, participants with diagnosed cases of […]
February 14, 2019; Updated Nov. 12, 2019 BIOPAC Systems, Inc. Goleta, CA USA New “Smart Amplifiers” make it easier than ever for life science researchers to get great data Fast Setup & High Performance Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system […]
Effects of MDMA on attention to positive social cues for behavioral disorders The psychostimulant drug 3,4-methylenedioxymethamphetamine (MDMA) reportedly produces distinctive feelings of empathy, closeness with others and increased social behavior. Researchers are exploring the potential of this chemical for treatment of psychiatric disorders, such as autism spectrum disorder (ASD) and post-traumatic stress disorder (PTSD). This […]
A System to Measure Physiological Response During Social Interaction in VR Children with Autism Spectrum Disorder (ASD) have a difficult experience in responding to social cues and actions. This pilot study measured the effectiveness of Virtual Reality in creating a social environment for children, measured with a BIOPAC MP Series data acquisition system and Worldviz […]
