This experiment aims to evaluate the effectiveness of neurofeedback sessions in reducing stress and enhancing performance in astronauts. By conducting pre-flight and post-flight tests (including psychological assessments, muscle activity measurements, blood analyses for stress markers, and brain activity), researchers aim to understand how preflight neurofeedback training may impact psychological, physiological, and motor functions. This experiment can help train crews for future spaceflight and develop technologies to help mitigate stress and improve performance on Earth.
