When using electrodes: Prepare the electrode site by removing dead skin—unless recording EDA/GSR—using an ELPAD and cotton swabs with water. If recording EDA/GSR, see EDA (GSR) subject preparation for guidelines.…
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…
Des système, solutions pour de meilleures données, au service d’une Science de qualité Résultats reproductibles – pour un ou plusieurs sujets, une ou plusieurs expériences Les laboratoires de recherche d’aujourd’hui…
For bioimpedances measured across the thorax using the EBI100C, a small impedance change is observed with each inspiration and expiration. For respiration monitoring, electrodes are placed across the mid-thorax along…
Reusable and disposable EDA/GSR electrodes both use isotonic gel but the formulas are different so results will be almost identical but will show a small difference. The researcher should compare…
The Reaction Time lesson demonstrates the effect of learning and physiological processes on reaction times. Students hear two presentation schedules of clicks through a set of headphones. With electrodes in…

Considerations in Selecting Data Acquisition & Analysis Systems for Psychophysiological Research By Joseph Aditi, Ph.D. Print friendly version: Selecting Psychophysiological Data Systems Introduction In 2017, only 20.51% of the total applicants for…
Record and analyze single-fiber potentials with a concentric needle electrode (EL451). Set the EMG100C to a 100 Hz – 5 kHz recording bandwidth. For improved rejection of low frequency background…
Political scientist Gregg Murray, Ph.D. recently published a post on Psychology Today regarding electrophysiological cues in highly political individuals. In it, he discusses the inherent biases of those identifying with a certain political…
Recommended for use when applying a stimulus to animal subjects and tissue preparations ELSTM1 Unshielded Stimulation Bar Electrode for Research Systems with BNC connector ELSTM2 Needle electrode has a BNC…
Biopac Science Lab with the stimulus response kit comes with one lesson focused on stimulus response: Lesson 11 — Reaction Time Fixed and Pseudo-random Intervals Lesson 11 demonstrates the effect…
BIOPAC Systems, Inc. has released a new application note that lays out some generally recommended methods for recording data from subjects in the MRI or fMRI. Click here to request…
These Ag-AgCl disposable, stress test, snap electrodes have the same signal transmission as reusable electrodes, with added convenience and hygiene. Each peel-and-stick electrode is a foam base pre-gelled with hypoallergenic…
Models designed to infer stroke volumes based on changes in thoracic impedance rely on many simplifying assumptions. These assumptions are not universally valid. Consequently the relationship between measured impedances and…
Science Night at Adams Elementary (Santa Barbara, CA) encourages students to discover, play, explore and learn about the importance of science and engineering in daily life. BIOPAC set up a BioNomadix Wireless Smart…
BIOPAC offers a variety of surface EMG (sEMG) recording and analysis options. sEMG data can be recorded with reusable or disposable surface EMG electrodes sent to a wired, wireless, or…
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…
Transcranial Direct Current Stimulation (tDCS), High Definition Transcranial Direct Current Stimulation (HD-tDCS), and Transcranial Alternating Current Stimulation (tACS) are forms of electrical stimulation to effect neuro-modulation in the brain. These…
Tissue conductance measurements can be performed with the MCE100C using either AC or DC excitation currents. Use surface, needle or micro-electrodes to interface to the tissue. Use four electrodes to…
Transcranial magnetic stimulation (TMS) is a noninvasive method of studying brain functions and interconnections—it causes hyperpolarization or depolarization of neurons in specific or general parts of the brain. For TMS…
On the MP100/MP150: For unipolar recording you need as many amplifiers as you have sites to record from. For example, for 16 electrodes (not including 1 reference and 1 ground),…
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…
Capture muscle force data in real time. Features include improved reproducability between subjects, reduced setup time, no skin prep, and no electrodes.
To perform Visual Evoked Response (VER) and Flash Visual Evoked Potential (FVEP) studies, use the TSD122 Stroboscope and the averaging mode in AcqKnowledge. The stroboscope will trigger the MP System…
Our goal is generally to provide but not proscribe choices. As with electrode positioning, decisions about electrode type are best addressed via the literature and discussions with colleagues. That said,…
The best answers for this sort of question are found in the literature and via discussions with colleagues. Decisions about such things are matters of science, not technical support. In…
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…
