Functional near-infrared spectroscopy (fNIRS) measures changes in oxygen levels in the brain by utilizing near-infrared light to detect hemodynamic responses. When neurons in the brain become active, they require more oxygen, leading to an increase in blood flow to that specific area. fNIRS detects this increase in oxygenated hemoglobin levels, providing a real-time measurement of brain activity.
One of the advantages of using fNIRS over other neuroimaging techniques like functional magnetic resonance imaging (fMRI) is its portability and ease of use. fNIRS devices are non-invasive, comfortable for the participant, and can be used in a variety of settings, including during natural movements. Additionally, fNIRS has a higher temporal resolution, allowing for the monitoring of rapid changes in brain activity.

Before we talk about what you'll experience from doing neurofeedback we need to step back and talk about what is happening in the brain that neurofeedback addresses. The brain is a machine of habit, and it creates automatic brainwave patterns and those patterns are meant to be solutions to our here-and-now problems. We have homework in front of us, need that focusing brainwaves pattern. When those patterns are not in alignment with our present needs we call them "symptoms" or "problems", such as feeling anxious or being scatter-brained. Even if these patterns are maladaptive, the brain tends to repeat them and requires a nudge to change. In order for new patterns to be created, old ones must first be disrupted. This is where neurofeedback comes in.

fNIRS can be effectively used to study brain activity in infants and young children. Its non-invasive nature and ability to be used in naturalistic settings make it ideal for studying developing brains. fNIRS has been used in research to investigate cognitive processes, language development, and social interactions in infants and young children.
The main limitation of fNIRS in terms of spatial resolution compared to other imaging techniques like fMRI is its inability to provide detailed information about deep brain structures. fNIRS primarily measures activity in the outer layers of the brain, limiting its ability to capture activity in deeper regions. This makes fNIRS more suitable for studying cortical brain activity rather than subcortical structures.
fNIRS differentiates between changes in oxygen levels due to neural activity versus changes due to other factors like blood flow by using multiple wavelengths of light to measure oxygenated and deoxygenated hemoglobin levels. By analyzing the ratio of these two types of hemoglobin, fNIRS can isolate changes in oxygen levels specifically related to neural activity, providing a more accurate representation of brain function.
Specific brain regions that are more easily studied using fNIRS compared to other imaging techniques include the prefrontal cortex, motor cortex, and visual cortex. These areas are located closer to the surface of the brain, making them more accessible to fNIRS measurements. Research has shown that fNIRS is particularly effective in studying cognitive processes, motor function, and visual perception in these regions.
The cost of fNIRS devices is generally lower compared to other neuroimaging technologies like electroencephalography (EEG) or fMRI. fNIRS systems are typically more affordable to purchase and maintain, making them a cost-effective option for researchers and clinicians. This lower cost, combined with the ease of use and portability of fNIRS devices, makes them a valuable tool for studying brain function in various populations and settings.
Neurofeedback therapy equipment has shown promise in treating communication disorders such as aphasia, dysarthria, and apraxia. By utilizing advanced technology to monitor brainwave activity and provide real-time feedback, individuals with communication difficulties can learn to regulate their brain function and improve speech and language skills. This innovative approach targets specific neural pathways associated with language processing, helping individuals with communication disorders to enhance their ability to express themselves effectively. Research suggests that neurofeedback therapy equipment can be a valuable tool in the comprehensive treatment plan for individuals struggling with communication impairments.
Neurofeedback systems utilize advanced technology to concurrently monitor various physiological signals such as brainwaves, heart rate, skin conductance, and muscle tension. These systems incorporate sensors and electrodes to capture real-time data on the body's responses to stimuli. By analyzing this information, neurofeedback systems can provide feedback to the user on their physiological state and guide them towards achieving optimal brain function and emotional regulation. The integration of multiple sensors allows for a comprehensive assessment of the individual's physiological responses, enabling a more personalized and effective neurofeedback training program. Additionally, the ability to monitor multiple signals simultaneously enhances the accuracy and reliability of the feedback provided by the system.
Neurofeedback therapy equipment has shown promise in treating substance abuse disorders by targeting specific brainwave patterns associated with addiction and cravings. By utilizing real-time feedback to train the brain to regulate these patterns, individuals may experience reduced cravings, improved impulse control, and enhanced emotional regulation. This non-invasive and drug-free approach can complement traditional substance abuse treatment methods, such as therapy and medication, to provide a comprehensive and personalized treatment plan. Research suggests that neurofeedback therapy may help individuals with substance abuse disorders achieve long-term sobriety by addressing underlying neurological imbalances that contribute to addictive behaviors. While more studies are needed to fully understand the effectiveness of neurofeedback therapy for substance abuse, preliminary evidence indicates its potential as a valuable tool in addiction treatment.
Neurofeedback systems utilize impedance monitoring to detect changes in electrode impedance during sessions. When impedance levels fluctuate, the system automatically adjusts the signal processing parameters to maintain optimal performance. This adaptive mechanism ensures that the neurofeedback training remains effective and accurate, despite variations in electrode impedance. By continuously monitoring and adapting to impedance changes, the system can provide consistent and reliable feedback to the user, enhancing the overall training experience. Additionally, the system may prompt the user or operator to check and adjust electrode placement if significant impedance changes are detected, further optimizing the neurofeedback session. Overall, the ability of neurofeedback systems to adapt to changes in electrode impedance contributes to the success and efficacy of the training process.
Neurofeedback therapy equipment has shown promise in improving memory function through its ability to train the brain to regulate its own activity. By providing real-time feedback on brainwave patterns, neurofeedback therapy equipment can help individuals enhance their cognitive abilities, including memory retention and recall.
