Neurofeedback, also known as EEG biofeedback, is a type of biofeedback that uses real-time feedback of brainwave activity to help individuals learn to self-regulate their brainwaves. This non-invasive technique aims to improve brain function and potentially alleviate symptoms of various neurological and mental health conditions.

How it works:
1. Brainwave Monitoring:
.
Sensors are placed on the scalp to measure electrical activity in the brain, which is then displayed as brainwaves on a computer.
2. Feedback:
.
The brainwave activity is translated into visual or auditory feedback, such as a game, video, or sound, that changes based on the brain's activity.
3. Self-Regulation:
.
By observing the feedback, individuals learn to consciously or subconsciously adjust their brainwave patterns, essentially training their brain to function more efficiently.
4. Reinforcement:
.
The feedback acts as a reward, reinforcing desired brainwave patterns, and over time, the brain learns to maintain these patterns, leading to improved regulation and potentially reduced symptoms.

Applications:
Neurofeedback is used to address a wide range of conditions, including:
ADHD: Improving focus, attention, and impulse control.
Anxiety: Reducing symptoms of anxiety and promoting relaxation.
Depression: Potentially improving mood and emotional regulation.
Insomnia: Helping to regulate sleep patterns and improve sleep quality.
Cognitive decline: Enhancing cognitive functions like memory and processing speed.
