fNIRS System for Brain Imaging Research

Shimadzu’s LABNIRS functional near-infrared spectroscopy (fNIRS) system offers multi-channel, high-sensitivity optical measurements of Blood Oxygen Level Dependent, BOLD, signals that originate in the cerebral cortex. 

LABNIRS offers flexibility for brain measurements through increased temporal and spatial resolution. Holders are specially designed to accept up to 40 sets of fibers, providing 142 channels, and images can be acquired at a rate of 6 ms. In addition, the LABNIRS system employs advanced semiconductor laser technology and photomultipliers to enhance signal acquisition and sensitivity. 

Flexible fiber placements allow users to arrange the sensors for effective measurement of any brain region of interest. To ensure the most stable measurements, users can also select from a range of flexible adjustable surface holders (FLASH), including whole head, newborn, and high density, to provide seamless mapping of the entire brain.

The LABNIRS system is built with scalability in mind. The system offers comprehensive options to serve the ever-growing needs of brain imaging research. These options include:

•    Video recording system
•    Simultaneous EEG measurements
•    Stimulus presentation system
•    Fiber extensions
•    MRI fusion software
•    3D position measurement system
•    Real-time data transfer system.

Physiological monitoring devices such as blood pressure, heart rate and eye tracking can be integrated into the data measurement to provide real-time comparisons to brain activity. An intuitive system interface provides easy operation in both measurement and analysis modes.

LABNIRS can be used for a wide variety of applications, include:

•    Neurorehabilitation
•    Brain Activity during Motor Control
•    Simultaneous Measurement with EEG
•    Education and Psychology Research
•    NIRS Signal Analysis Method
•    Investigating Inner Speech
•    Language Processing Functions
•    Mental Disorder Research
