Dear (f)NIRS Enthusiasts, we’re now active on Bluesky🦋🟡 While we deeply value the vibrant #NIRS #fNIRS community on X, its algorithms often prioritize less authentic interactions & limit meaningful discussions. In light of this, follow us on Bluesky: https://t.co/l4AwfbcuN5

🟡🔵 Muscle oxygenation does not appear to explain exercise intolerance in fibromyalgia, pointing researchers toward alternative mechanisms. Another strong example of how integrated muscle-brain #fNIRS #mNIRS supports clearer clinical understanding. 🔗 https://t.co/MjTx2xFqhe

During both submaximal and peak exercise, muscle oxygenation in the arm and leg, as well as cerebral deoxygenation, showed no significant differences between groups. Key insight:

🌟 Top Pick of the Year in Combined Muscle & Brain Research Pt. 2! Lehto et al. delivered a valuable publication by simultaneously measuring muscle & brain oxygenation in patients with fibromyalgia and healthy controls using combined NIRS. #fNIRS #mNIRS

🟡 Dual measurements provided a clear view of systemic and local oxygenation dynamics 🔵 #fNIRS revealed coordinated changes in cerebral and muscular oxygenation during breath holds 🟡 Findings contribute to a deeper understanding of autonomic and physiological adaptation

used both the PortaMon and PortaLite to investigate cardiovascular and oxygenation responses during breath holding, capturing a detailed picture of how the brain and muscles respond together under stress.

As we continue highlighting excellent research on our way to 1,500 publications, this week’s top pick focuses on combined brain and muscle insights. Allinger et al.

🔵 All training approaches led to meaningful improvements, highlighting that even short-term programs—regardless of modality—can help promote #HealthyAging A clear demonstration of how #NIRS strengthens evidence in exercise and aging research. 🔗 https://t.co/SJAhB7PVbU

Using the #PortaMon to monitor muscle oxygenation throughout the intervention, the team assessed how each training modality supported muscle function. Their conclusion: ...

🌟 Top Pick of the Year in Muscle Research Pt. 2! Citherlet et al. published a strong #NIRS study in Nature Scientific Reports evaluating short-term eccentric cycling in hypoxia, cycling with blood flow restriction, and traditional cycling in older adults.

🔵 NIRS revealed clear sex-related differences in muscle oxygenation metrics 🟡 Insights like these contribute to more targeted and individualized approaches in sports science

This week’s top pick comes from Perlet et al., who used the PortaMon to investigate how training history and sex-related differences shape NIRS-derived muscle values. 🟡 PortaMon allowed precise, non-invasive monitoring across varied training backgrounds

As we approach 1,500 publications using Artinis devices, we want to highlight some standout work in muscle research.

🔵 Greater DLPFC inter-brain synchrony helped reduce this shift. A compelling demonstration of how wearable hyperscanning #fNIRS advances real-world social neuroscience. 🔗 https://t.co/zX0W1ucE1r #Hyperscanning #SocialNeuroscience #GroupDynamics #BrainResearch

The team examined whether discussion in homogeneous groups increases extremity — and whether synchrony in the dorsolateral prefrontal cortex (DLPFC) can buffer this effect. Key findings: 🟡 Homogeneous groups became more extreme after discussion.

Focusing on inter-brain synchrony during moral alignment, the research provides new insight into how shared discussions shape collective judgments.

🌟 Top Pick of the Year in Brain Research Pt. 2! Sobeh et al. presented a standout 2025 study using the Brite to investigate how #fNIRS captures the neural dynamics behind group decision-making.

🟡 MediBrite meets regulatory requirements for medical use to bring clinical NIRS into real medical workflows. It combines portability, medical-grade compliance, and ease of use —empowering clinicians to use #fNIRS confidently. 🔗

Its flexibility makes it especially valuable in psychiatry, neurology, and neurorehabilitation. But challenges remain, from standardization to integration into clinical workflows. That’s where #MediBrite steps in.
