Neurotechnologies

For decades, altered states of consciousness have been used as a form of psychotherapy in transpersonal psychology. Although there are well-known techniques for inducing altered states of consciousness, such as holotropic breathwork, neurotechnology provides an alternative method for not only generating these states for transpersonal therapy but also for measuring the level of a state of consciousness. The goal of this chapter is to provide a review of the fundamental concepts of neurotechnology as well as the technologies that can be used to induce and measure altered states of consciousness for transpersonal psychotherapy.
