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 […]

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 […]

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 […]

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 […]

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 […]

A new application note from BIOPAC outlines the implementation details of determining emotional state on the basis of three physiological measures: Electrodermal Activity EDA), EMG – Zygomaticus, and EMG – Corrugator.

Biopac Student Lab sofware included with BSL Teaching Systems and BSL System Upgrades has been updated to BSL 4.0.2. New since the BSL 4.0.1 release… BSL Lessons for Blood Pressure and Heart Sounds include an output option for monitoring stethoscope sounds through headphones (including BIOPAC OUT1, OUT1A, or 40HP) via the MP Analog Output or headphone jack—a convenient, […]

For the second consecutive year, the top-viewed BIOPAC video was “EEG Frequency Analysis” using AcqKnowledge® software. AcqKnowledge is a powerful, intuituve data acquisition and analysis tool with automation and scoring routines that streamline complex analyses and provide reproducible results for an array of applications. Choose from 120+ tutorial screencasts at BIOPAC.COM or click below to watch the […]

AcqKnowledge software for  MP160, MP150, and MP36R research systems includes a fully-automated electrodermal activity (EDA) data scoring routine. The feature includes options for deriving phasic EDA from tonic EDA, locating skin conductance responses (SCR), and event-related EDA analysis. Watch the tutorial video now: Read the primer on EDA protocols and analyses to go from data acquisition […]

BIOPAC psychophysiological data solutions were used by the Duke University DiVE immersive environment lab in a study on human fear conditioning: Huff, N.C., Zielinski, D.J., Fecteau, M.E., Brady, R., LaBar, K.S. Human Fear Conditioning Conducted in Full Immersion 3-Dimensional Virtual Reality. J. Vis. Exp. (42), e1993, doi:10.3791/1993 (2010). Click to watch the JoVE video publication: […]
