BIOPAC® offers a series of amplifiers, electrodes, electrode leads, transducers, and stimulus options for safe data acquisition of physiological signals in the MRI environment.
Record physiological signals such as: Electrocardiogram (ECG), Electromyogram (EMG), Electroculogram (EOG), Electrogastrogram (EGG), Temperature, Respiration, Electrodermal Activity (EDA, EDR, SCL, SCR or GSR), Pulse, Hand Grip Strength (Dynamometry), CO2 and O2 Gas Analysis, Pulse Oximeter (SpO2), Finger Twitch, and a variety of pressure based signals.
Microvascular blood perfusion can be measured with the Laser Doppler Flow System. Electrical stimulation is also available for constant current and constant voltage electrical stimulation. Physiological signals in the MRI can be used for psychophysiological studies, neuromarketing, subject monitoring, and more.

An fNIR System provides researchers with real-time monitoring of tissue oxygenation in the brain as subjects take tests, perform tasks, view advertisements, experience ergonomic layouts, or receive stimulation. It allows researchers to quantitatively assess brain functions—such as attention, memory, planning, and problem solving—while individuals perform cognitive tasks. Monitor cognitive state of the subject in natural environments.
Continuous Wave fNIR imaging offers researchers a portable functional near-infrared (fNIR) imaging research tool capable of monitoring brain’s hemodynamics and thereby the cognitive state of the subject in natural environments. fNIR technology employs specific wavelengths in an optical frequency window which can easily pass through a few centimeters for most tissue, and allow monitoring blood oxygenation changes but monitoring back-scattered light intensity. The relative changes of light intensity across time are due to changes in oxy- and deoxy-hemoglobin and provides information about neural activity.
► fNIR is the only stand-alone and field-deployable technology able to determine localized brain activity.
► Clean data: fNIR devices provide raw light intensity and oxygenation data as well as modern noise reduction methods and analysis options for researchers.
► Easy to apply: data collection can start within 5 minutes.
► Robust system: sensors have been tested thru 10,000 flex cycles.
► Safe: Every fNIR system is shipped with a high capacity isolation transformer.
► Flexible: integrate with other physiological and neurobehavioral measures that assess human brain activity, including eye tracking, pupil reflex, respiration and electrodermal activity; easily syncs port with third party stimuli presentation systems.
fNIR is a powerful near-infrared spectroscopy imaging tool for in-lab cognitive tests and neuromarketing. This technique measures NIR light absorbance in blood of hemoglobin with and without oxygen and provides information about ongoing brain activity similar to functional MRI studies. It eliminates many of the drawbacks of fMRI and provides a safe, affordable, noninvasive solution for cognitive function assessment. The technology empowers researchers by providing greater flexibility for study design, including working within complex lab environments and operating in non-traditional lab locations for field studies (neuromarketing). The fNIR device provides relative change in hemoglobin levels, calculated using a modified Beer-Lambert law.
