Huxley discusses how the brain is actively perceiving everything; sensations, memories, perceptions. However, our survival is contingent on a bottleneck that funnels reality and cultivates consciousness. Mescaline, a psychedelic, interferes with this bottleneck, creating sensations and interference with consciousness. In neuroscience, this may be called the "default mode network" and could also explain psychosis.
