Exploring early brain development in real-world settings: an interview with Dr. Paola Pinti
Dr. Paola Pinti is a Senior Research Laboratory Developer in the Birkbeck ToddlerLab. In this interview, she shares her experience in neuroscience, her work in the ToddlerLab, and the usage of a multimodal set-up to investigate behavior and brain of preschool children.
Integrating real-time fNIRS with biofeedback to promote fluency in people who stutter
Over at the Speech Lab here in University College London, we are in the midst of data collection with the wearable fNIRS system, Brite. We’ve been investigating the hemodynamic biomarkers of stuttering along with cortical responses of altered feedback during speech.
Exploring the infant brain with fNIRS
Testing young babies, between 0 and 2 years of age, is definitely fun, but it also comes with challenges. We asked several developmental researchers to point out the main difficulties they typically encounter and what features an infant-friendly NIRS should have. So, what are these challenges and what can researchers and technology do to overcome them?
How to: Start a measurement and do a short analysis
If you don’t have time to read our extensive manuals, but would still like some quick pointers on how to start a measurement with one of our state of the art fNIRS devices… you’re in the right place! In this blog we will get you set-up in no time and discuss some of the analysis options our proprietary software, OxySoft, offers.
Brite MKII: Wearable, Highly-Flexible, Optimized, Accurate NIRS!
Meet the latest Artinis wearable NIRS system, designed for brain imaging in a wide range of settings and populations. Optical imaging was never so easy!
Heart rate extraction from NIRS signal
A commonly asked question is “What are the advantages of NIRS over EEG?”. NIRS signals are, in general, less susceptible to artifacts like motion artifacts or electrical noises. There are, however, also physiological components such as heartbeat, breathing, and Mayer-waves present in the signal. Although not an artifact, these components are usually filtered out since they are not useful in determining the pure hemodynamic response signal of the brain. Nevertheless, there is interesting information in the heartbeat. In this blog, we talk about taking advantage of the heartbeat in the NIRS signals and extracting the heart rate signal from them.
How to clean your Artinis NIRS systems and accessories?
COVID-19 has had a major impact on all of us. For a while, Universities were closed and research was put on hold. Now slowly but surely, we are going back to the labs and starting our experiments again. NIRS experiments include contact with patients and research participants, we therefore find it important to inform you about how to clean the Artinis NIRS devices.
The importance of being precise: using PsychoPy for stimulus presentation and OxySoft for triggering
You’ve got your NIRS device ready and have already thought of the protocol for your next experiment. You have a clear picture of it in your head: you can see the subjects with the NIRS cap on facing a PC monitor showing each of the instructions and stimuli at the exact timing you were aiming for. Timestamps for each event are automatically saved and once the session is over, you are ready to go for the analysis. Sounds nice, right? How simple is it, though? Well, turns out it’s quite simple, actually. You just need the right tools, and the combination of PsychoPy and Oxysoft is a perfect match!
Laser and LED, what is the difference in NIRS?
As an application Specialist at Artinis Medical Systems I get asked a lot what the differences are between lasers and LEDs. So, therefore a small blog to answer this question once and for all. Both laser and LED have their specific pros and cons. It depends very much on your research requirements what technique is best for you. I have broken down the differences in measuring depth, portability, pricing, wavelengths and safety in this blog.
How to set up your Brite video
Watch how easy setting up your Brite is!
The Brite is the only wearable fNIRS device worldwide that can measure the oxy-, deoxy- and total hemoglobin in every part of the head, e.g. prefrontal cortex, motor cortex, or visual cortex.
