Adding vagus nerve stimulation to training sessions may boost how well sounds are perceived

Just as a musician can train to more sharply distinguish subtle differences in pitch, mammals can improve their ability to interpret hearing, vision, and other senses with practice. This process, which is called perceptual learning, may be enhanced by activating a major nerve that connects the brain to nearly every organ in the body, a new study in mice shows.
