Abstract

In contrast to improvement in emotion recognition bias by traditional antidepressants, the authors report preliminary findings that changes in facial emotion recognition are not associated with response of depressive symptoms after repeated ketamine infusions or relapse during follow-up in treatment-resistant depression.

New World Tryptamine Hallucinogens and the Neuroscience of Ayahuasca

Abstract

New World indigenous peoples are noted for their sophisticated use of psychedelic plants in shamanic and ethnomedical practices. The use of psychedelic plant preparations among New World tribes is far more prevalent than in the Old World. Yet, although these preparations are botanically diverse, almost all are chemically similar in that their active principles are tryptamine derivatives, either DMT or related constituents. Part 1 of this paper provides an ethnopharmacological overview of the major tryptamine-containing New World hallucinogens.
