Intracellular Action Potential lesson released for Biopac Student Lab

Intracellular Action Potential can now be studied with a new Biopac Student Lab PRO Lesson that provides a detailed physiology introduction (developed in conjunction with Department of Biology, University of Northern Iowa, Cedar Falls) and a graph template file to simplify setup and recording. Students make an intracellular electrical recording in cardiac tissue, observe the […]

Mobita 32-Channel Wireless Acquisition with AcqKnowledge 4.4

32 channels of wireless data with 3D accelerometer and trigger channel BIOPAC now offers the Mobita® wearable physiological signal amplifier system that can record up to 32 channels of high-fidelity wireless data. The system can either telemeter data back to a computer running AcqKnowledge for real-time display and analysis of the signals, or record it locally for […]

MRI Gating Introduction features BIOPAC Solutions

At BIOPAC, we’re dedicated to enabling greater discovery. There are only a few things that make us more proud than seeing our research tools being used to help teach others. Researchers and educators alike will be interested in the informative mri-q.com website, where our products are being used as examples to inform readers about MRI […]

Recording Cardiac Output Measurements in an MRI

Acting to support researchers affiliated with UC Santa Barbara’s Department of Psychological & Brain Sciences, BIOPAC developed a specialized Noninvasive Cardiac Output amplifier module designed for operation in an MRI. The team successfully captured and analyzed impedance cardiography (ICG) from a subject during fMRI. Titled “Simultaneous acquisition of functional magnetic resonance images and impedance cardiography,” […]

Recording Great Physiological Data in 7T Ultra-High Field fMRI

Live data including raw EDA (top line), raw EMG (third line), and filtered EMG (last line) in AcqKnowledge  BIOPAC Systems products were recently used for neurophysiological mapping on a human subject inside a 7T scanner for a study at Auburn University. The study was also coauthored by two of our own BIOPAC members, Ken Graap […]

Seizure Detection Software and Hardware Available – watch a demo video now

Automated Seizure Detection with AcqKnowledge AcqKnowledge software now provides a routine for locating seizures in long-term small animal EEG recordings…automatically identify and score seizures using the spike frequency method. The system processes user-defined rules and time periods to define and classify seizure activity within a particular epoch. Seizure interval and intensity results are output to […]

tDCS and HD-tDCS Neuronal Stimulation App Note released

Transcranial Direct Current Stimulation (tDCS) is an electrical stimulation method, which employs a direct current of value typically between 1 and 2 milliamps (ma). This method is typically oriented to neuronal stimulation in the brain. Depending on the type of electrodes used for stimulation, and their associated placement on the scalp and body, Transcranial Direct […]

Testing Correlation between Players Strength and Head Impact Severity

Football season is in full swing as millions of people gather to watch and celebrate one of America’s favorite pastimes. Along with the familiar storylines that surround the sport’s season (wins and losses, rivalries, etc.) one news item continues to be a major talking point: the increased concern over player safety. Players of all ages […]

VEP Lesson Updated

BIOPAC's Visual Evoked Potential lesson guides students to record a baseline and two experimental Visual Evoked Potentials segments.   Each experimental segment presents a visual stimulus to a human subject and runs at least one minute so that over 100 strobe flashes (at 2 Hz rate) are output and the BSL System records at least […]

Wireless Neuro-Actuator Prosthetic uses BioNomadix EMG

A wireless neuro-actuator prosthetic was created using BIOPAC's wireless hardware and additional custom hardware. The electromyogram of both opponens pollicis (thumb flex) and pronator quadratus (wrist rotate) was recorded from the Subject's palms and wrists, and the real-time, high-resolution surface EMG signal was processed to control the grip and rotation of remote handgrips. For each […]
