Study Overview:

The study investigated the effectiveness of Mendi, a near-infrared spectroscopy (fNIRS) device, in measuring brain activity, specifically in the prefrontal cortex, which is crucial for working memory.

Key Points:

Innovation in Brain Imaging: The Mendi device represents a significant advancement in neuroimaging. Unlike traditional, complex fNIRS systems confined to labs, Mendi is portable and user-friendly, facilitating broader research applications.
Methodology: Participants performed an n-back task, a common test for working memory, under varying levels of difficulty. The Mendi device measured changes in oxyhemoglobin concentrations in the prefrontal cortex, indicating brain activity levels.
Findings: The study successfully demonstrated that the Mendi device could differentiate between low and high cognitive loads. Increased brain activity was observed during more challenging tasks (three-back) compared to easier ones (one-back).
Implications: This validation of Mendi as a reliable tool for assessing working memory load opens up possibilities for conducting neuroscientific research in more diverse and natural settings, and with a wider range of participants.

Conclusion:

The Mendi mobile fNIRS system is validated as an effective tool for measuring working memory load. By moving away from the confines and complexities of traditional lab-based neuroimaging techniques, Mendi paves the way for more inclusive and diverse brain studies in real-world settings. Its ease of use and portability allow researchers to examine brain activity in a variety of environments and among different population groups, including those who might be unable to participate in traditional lab-based studies.

About Mendi

⭐️What sets Mendi apart:

In a world increasingly fascinated with brain health, the emergence of brain training devices has sparked a new wave of interest in cognitive enhancement. Amidst this rising tide, Mendi emerges as a standout innovation, not just for its novel approach but also for its groundbreaking use of functional near-infrared spectroscopy (fNIRS) technology, a significant leap from the commonly used EEG sensors in other devices.

For years, brain training devices have promised to boost cognitive functions, using EEG (electroencephalography) sensors to measure brainwaves. While beneficial, these devices often offered limited insights, focusing mainly on brainwave patterns. However, the landscape is changing thanks to Mendi.

fNIRS technology offers a more comprehensive view of brain activity compared to EEG. By measuring changes in blood oxygenation, it provides direct insights into how different areas of the brain respond to cognitive tasks. Mendi harnesses this technology in a portable, non-invasive form, making it a game-changer in personal brain health.

💰Affordability:

Unlike its predecessors, Mendi employs fNIRS technology, a more advanced approach that measures brain activity by monitoring blood flow and oxygenation in the brain. This technique, typically reserved for high-end laboratory research costing upwards of $10,000, is now made accessible and affordable with Mendi's sleek, user-friendly design priced at a mere $299.
