Neurofeedback is a brain training tool that aims to improve the physiological functioning of the brain. Similar to other brain training tools out there, such as Lumos Neuro, here's a quick overview of what you should know and consider before delving into the science behind the technique.
How Does It Work?
Put simply, neurofeedback works by measuring the brain's activity (i.e., how the electrical activity in the brain varies during the process of thinking or performing a task) and then providing real-time visual feedback about that activity. In other words, the concept behind neurofeedback is to allow the user to "see" their brain functioning so that they can more accurately train it.
For example, if you're trying to concentrate but find your mind wandering off to irrelevant thoughts (like whether that cute girl on the other side of the gym is looking at you or not), you'll be provided with an instantaneous visual image of your brain activity so that you can quickly determine if and when your mind wanders and brings you back to the present moment. In turn, this may help you to improve your concentration and focus much more effectively.
What Hardware is Needed?
Similar to other brain training tools, neurofeedback is most commonly implemented using electroencephalography (EEG), which involves recording the electrical activity in the brain using small electrical sensors placed on the scalp. The sensors are noninvasive and can be comfortably worn for the entire duration of a session. Because EEG is a relatively straightforward technique to implement, most advanced neurofeedback systems are compatible with this type of hardware. However, if you're looking to dive into the deep science behind the technique, you might want to consider investing in a neurofeedback headset that is built specifically for this purpose.
Where Can I Study It?
Because neurofeedback is a relatively novel technique, the majority of the available literature focuses on case studies and animal research. However, given its relatively straightforward and noninvasive nature, it is certainly something that could be further explored in the clinic. In particular, if you're interested in studying the efficacy of neurofeedback in the treatment of ADHD, anxiety, and depression, you might want to consider looking into institutes like the National Institutes of Health or the Wellcome Trust, which both have an active neurofeedback program.
The Cost
The cost for neurofeedback is rather minimal compared to other medical procedures and devices. In fact, similar to the price of a smartwatch or fitness tracker, the cost of an EEG cap plus 16-channel neurofeedback equipment is around £600. This is a significant cost savings compared to other brain training techniques (e.g., Lumos Neuro and Cogill Mindfulness Training) and even pharmaceuticals (e.g., Ritalin and Adderall).
Summary
In summary, if you're looking for a brain training tool that can help you improve your concentration, you might want to consider trying out neurofeedback. Similar to other brain training tools, neurofeedback works by measuring the brain's activity and then providing visual feedback about that activity. However, because it incorporates a cognitive training component (i.e., training the brain to control certain thought processes) rather than just providing peripheral nervous system stimulation like many traditional fitness tools, it may prove to be more effective in the long term than others.
