When a person takes mescaline, psilocybin, or LSD, electrically-induced phosphenes—patterns perceived without external visual input—become more intense, broader in bandwidth, and more numerous. In one subject, two control patterns increased in intensity and bandwidth, and many new phosphene patterns with large bandwidth and intensity appeared, especially during simultaneous electrical and maximum chemical stimulation. These results suggest a cybernetic model of a pulse-driven phosphene resonator.
