Pros and cons of fnirs arduino

Pros and cons of fnirs arduino

When it comes to the world of neuroimaging, functional near-infrared spectroscopy (fNIRS) has gained popularity due to its non-invasive nature and portability. And when combined with the power of Arduino, a microcontroller platform, researchers have found an innovative way to enhance their experiments. But like any technology, there are pros and cons to using fNIRS Arduino.

One significant advantage is the flexibility it offers in terms of experiment design. With fNIRS Arduino, researchers can easily customize their setups according to their specific needs. The open-source nature of both fNIRS and Arduino allows for endless possibilities in terms of hardware configurations and data analysis techniques.

Another benefit is cost-effectiveness. Compared to other neuroimaging techniques such as functional magnetic resonance imaging (fMRI), fNIRS Arduino provides a more affordable option without compromising on quality. This makes it accessible to researchers working on tight budgets or those conducting studies in resource-limited settings.

Additionally, fNIRS Arduino enables real-time monitoring capabilities. Researchers can obtain immediate feedback during experiments, allowing them to make adjustments on-the-go if necessary. This real-time feedback can be valuable in various fields such as cognitive neuroscience or rehabilitation therapies where precise timing is crucial.

However, there are also some limitations associated with using fNIRS Arduino. One challenge is its relatively lower spatial resolution compared to other neuroimaging methods like fMRI or electroencephalography (EEG). While fNIRS captures hemodynamic changes occurring within the brain’s cortex region accurately, it may not provide detailed information about deep brain structures.

Another limitation relates to signal contamination from external sources such as ambient light or motion artifacts caused by participant movement during experiments. Researchers need advanced signal processing algorithms or additional measures like optode fixation devices to mitigate these issues effectively.

Moreover, despite being portable and flexible compared to traditional neuroimaging tools, fNIRS Arduino still requires some level of technical expertise to set up and
