Progress and prospect of non-invasive military cognitive neural training

As cognitive neuroscience enters the era of technology application, military psychological training has evolved from traditional behavioral training to cognitive neural training based on neuroimaging, artificial intelligence, virtual reality, and other technologies. Cognitive neural training includes both invasive and non-invasive types, which can be used not only as an adjunct treatment for military occupation-related neuropsychiatric disorders, but also as preventive training that targets the brain to enhance cognitive ablity, regulate emotion, and shape behavior. In this article, we focused on non-invasive cognitive neural training, mainly sorting out the advanced literature concerning non-invasive brain stimulation represented by repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and low-intensity focused ultrasound, as well as neurofeedback mediated by electroencephalography, functional magnetic resonance imaging, and functional near-infrared spectroscopy. We prospected the development trend of intelligent, personalized, multimodal, sensory and wearable neural training, and brought forward and discussed the problems that need our attention in the research and application of cognitive neural training in our army.
