A repeated dose study and a neurochemical mechanism study designed to evaluate the capacity of 5HT1A agonists and 5HT2A antagonists to block the effects of ayahuasca will both be conducted soon. These studies are also included as part of the program of research including a SPECT study of regional blood flow after ayahuasca that is already in progress, as described above. The investigators are seeking funding to support this study.
