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,” […]
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 […]
AcqKnowledge 4.4 Available Now AcqKnowledge is an interactive, intuitive program that lets you instantly view, measure, transform, replay, and analyze life science data. Perform complex data acquisition, stimulation, triggering and analyses using simple pull-down menus and dialogs. AcqKnowledge software has been cited in thousands of peer reviewed publications and is used by thousands of labs […]
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 […]
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 […]
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 […]
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, […]
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: […]
