Ingesting the South American hallucinogenic beverage ayahuasca reduced the rate of perceptual alternations in a binocular rivalry task, increased the duration of one percept, and produced evidence of phenomenal fusion. These findings align with brain activation studies showing right cortical activation under hallucinogens and support the concept of interhemispheric fusion in altered states of consciousness, rather than the earlier theory of changes in hemispheric integration.
