Se problematiza la idea de laicidad a partir de los usos de enteógenos o plantas sagradas, como la ayahuasca. Se analiza el caso de una retención de ayahuasca (brebaje psicoactivo de origen amazónico) ocurrida en 2009 en la Aduana del Chuy, proveniente de Brasil, dirigida a una iglesia del Santo Daime en Uruguay, pero que no alcanzó aun su destino luego de la intervención de la justicia y el...

In the past decade, an increasing number of clinical trials are reporting evidence that psychedelics or serotonergic hallucinogens (such as lysergic acid diethylamide, psilocybin, and ayahuasca/dimethyltryptamine) could be effective in the treatment of mood, anxiety, and substance use disorders. The mechanisms responsible for these effects are not fully understood but seem to involve changes in...

Hallucinations possess two main components: (i) a sensory content; (ii) a sense that the sensory content is real. Influential models of schizophrenic hallucination claim that both the sensory content and the sense of reality can be explained in terms of metacognitive dysfunction. This chapter assesses whether such a claim holds for schizophrenic and drug-induced hallucinations; it further...

Serotonergic hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT), are famous for their capacity to temporally and profoundly alter an individual's visual experiences. These visual alterations show consistent attributes despite large inter- and intra-individual variances. Many reports document a common perception of colors as more saturated, with...

The effects of hallucinogenic drugs on the human brain have been studied since the earliest days of neuroimaging in the 1990s. However, approaches are often hard to compare and results are heterogeneous. In this chapter, we summarize studies investigating the effects of hallucinogens on the resting brain, with a special emphasis on replicability and limitations. In previous studies,...

"Nascidas durante o século XX, a Barquinha, o Santo Daime e a União do Vegetal, conhecidas como as religiões ayahuasqueiras brasileiras, se mantiveram circunscritas à região norte do Brasil pelo menos até o início dos anos de 1970. Desde então, o Santo Daime e a União do Vegetal têm se expandido significativamente, cada qual à sua maneira, alcançando todas as regiões do país, cruzando as...

Resumo Recentemente, trabalhos de Ernesto Neto ganharam destaque em museus de arte em Bilbao, São Paulo e Viena. Tiravam parte de sua força do fato de remeterem a rituais de cura com ayahuasca dos Huni Kuin (Kaxinawa). Observa-se certo paralelismo entre essa conquista de espaço para a presença indígena no sistema das artes e a chegada dos índios ao circuito urbano da ayahuasca. A circulação de...
