NIRX is a world-leader in providing integrated solutions for fNIRS neuro-imaging.  In 1988 we introduced the concept of tomographic imaging (i.e., multi-distance measurements) in dense scattered media base on diffusely scattered light. This approach has since been widely adapted and has served to launch the modern day field of fNIRS tomography.

Through our offices in Berlin, Los Angeles, New York and São Paolo, our engineers and grant-funded investigators are providing a growing number of research teams world-wide with comprehensive technology solutions for the most demanding investigative applications.



Webinar: fNIRS and Brain Computer Interface for Communication

We are extremely happy to announce NIRx first webinar to be held on the 8th of June, 4pm CEST/ 10am EDT. The webinar will be focused on how fNIRS technology can be used for BCI applications. We are extremely pleased to announce Dr. Ujwal Chaudhary and Dr. Bettina Sorger as our guest speakers. 

Discussion will focus on the basic principles of fNIRS and BCI, technical setup and guidelines for running a successful fNIRS study and a comparison of fNIRS with other functional neuroimaging methods. Experts will highlight their groundbreaking research in the field of fNIRS based BCI for communication with healthy subjects and patients in completely locked-in state. Specifically, Dr. Ujway Chaudhary (University of Tuebingen) will share results of his research with healthy participants and patients with locked-in syndrome due to Amyotrophic Lateral Sclerosis (ALS). Dr. Bettina Sorger (Maastricht University) will present data from a recent study demonstrating the feasibility of a multiple-choice fNIRS-based communication BCI using differently timed motory imagery as informative encoding strategy. 


Exploring Optical Neuroimaging

NIRx was founded by functional near-infrared spectroscopy (fNIRS) researchers.  We continue to focus 100% of our efforts to advancing and promoting this innovative and promising research tool.

NIRx believe in the importance of constantly contributing new information to the fNIRS community.  We are always adding to our downloadable material and hope you will learn something!
