A training device (1000) using a method for decoding neural activity is provided with a brain activity detector (108) for detecting brain activity in a specific region in the brain of a test subject, a calculation processor (102), and an output device (130) for indicating the neural feedback information (presented information) to the test subject. The calculation processor (102) decodes the activation pattern of cranial nerves, calculates the reward value based on the degree of approximation of the decoded pattern to the pattern of the target activation acquired beforehand for the event that becomes the training target, and generates the presented information corresponding to the reward value.
