Research Abstract

Dreaming is a subjective experience during sleep. However, the neural basis is still unknown. We developed an experimental and computational methods to obtain and analyze dream-related data(dream reports and brain activity during dreaming) efficiently and successively. In the near future, the introduced methods may work to externalize the vivid image of dreaming, and furthermore, may contribute to consolidate the theories of dreaming.
