Some therapies let people watch a real-time display of their own brain activity and learn to nudge it in a healthier direction.
Neurofeedback measures brain activity in real time, often via scalp electrodes like an EEG, and displays it back as a visual or auditory signal, a moving graph or changing tone. Through repeated sessions watching this feedback, people learn to recognize and influence their own brain patterns, studied for conditions like ADHD and anxiety.
Dialysis filters blood waste for kidney failure, unrelated to brain training. Photosynthesis is how plants convert sunlight into energy, also unrelated to training human brain activity.
Scientific opinion remains genuinely mixed, since results vary between individuals and studies, and researchers are still clarifying how strong and lasting its effects are, an honest caveat compared to more established treatments.
