GOLETA, CA--(Marketwire - May 5, 2009) - BIOPAC Systems,
Inc. announces new functional near infrared (fNIR) optical imaging
systems to measure oxygen level changes in the prefrontal cortex of human
subjects.
The fNIR system provides researchers with real-time monitoring of tissue
oxygenation in the brain as subjects take tests, perform tasks, or receive
stimulation. It allows researchers to quantitatively assess brain functions
-- such as attention, memory, planning, and problem solving -- while
individuals perform cognitive tasks.
fNIR is a powerful near-infrared spectroscopy imaging tool for in-lab
cognitive tests. 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. fNIR results have been tested to agree with
fMRI results.
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. BIOPAC
Systems, Inc. has partnered with fNIR Devices to offer the technology as
part of BIOPAC's range of data
acquisition & analysis systems for the life sciences. Davood Tashayyod,
CEO, fNIR Devices, says, "We created a headband for continuous NIR
spectroscopy to obtain neurovascular coupling data while keeping subjects
comfortable and free to move around. Our fNIR results have been tested to
agree with fMRI results."
fNIR data combines with physiological signals acquired through BIOPAC's
data acquisition and analysis systems, such as ECG, respiration, cardiac
output, blood pressure, electrodermal activity and stimulus response
markers;
AcqKnowledge software provides automated analysis tools for event
related potentials and ensemble averaging. The system interfaces with most
stimulus presentation systems (such as E-Prime or SuperLab) and BIOPAC's
range of Virtual Reality systems.
BIOPAC CEO Frazer Findlay says, "Combining fNIR technology with BIOPAC's
physiological monitoring systems further expands BIOPAC's human-based
neurophysiological product line and puts BIOPAC in the forefront of
advanced noninvasive subject monitoring."
The fNIR100 is suitable for a wide range of applications: Human Performance
Assessment (Cognitive Function), Depth of Anesthesia Monitoring, Pain
Assessment, Brain Computer Interface, Neurorehabilitation, Virtual Reality,
Autism, Credibility Assessment.
