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 on a screen. This feedback allows users to see their brain patterns and make adjustments to improve mental states. The goal of neurofeedback is to promote self-regulation of brain activity, which can lead to improvements in various conditions such as ADHD, anxiety, and depression. It is often used as a complementary therapy alongside traditional treatments, aiming to enhance overall mental well-being.
