Neurofeedback is a type of biofeedback that uses real-time monitoring of brain activity to help individuals learn how to regulate their brain function. By using sensors placed on the scalp, it measures electrical activity in the brain, often displayed as visual or auditory feedback. This process aims to teach users how to enhance desirable brain patterns and reduce unwanted ones. The technique is often used to address various conditions, such as ADHD, anxiety, and depression. While some studies suggest it can be beneficial, more research is needed to fully understand its effectiveness and long-term impacts on mental health.
