ABSTRACT Psychoactive drugs profoundly alter consciousness, but the neural mechanisms by which they do so remain poorly understood. Global workspace theory may provide a framework for investigating these mechanisms. The global workspace, a candidate neural substrate of consciousness, is a set of brain regions that integrate and disseminate information to the rest of the brain. According to a recent model, the integrators, or “gateways,” are characterized by synergistic interactions with other brain regions, while the disseminators, or “broadcasters,” exhibit redundant interactions. Here, we me
