Epistemologias para convivialidade ou Zumbificação

<p>Inspirado no pensamento de Frantz Fanon, este texto é um diagnóstico do tempo presente encenado como uma “reação psicótica”, cujo esperado efeito colateral é fazer avançar a noção de convivialidade como um espaço de experimentação analítica, onde desigualdade e diferença compartilham a condição de isonomia conceitual. O experimento específico aqui realizado tenta atingir esse objetivo fundindo diferentes registros escriturais e explorando o repertório vernacular da junção brasileira de um Atlântico afro-indígena. Sua aposta analítica, a ideia de zumbificação, é o esboço de uma posição epistemológica cujo trabalho consiste em uma cinética de (pelo menos) três movimentos: 1) a posicionalidade necessária para fazer exigências políticas; 2) o decentramento necessário para atenuar os efeitos prejudiciais tanto do essencialismo (mesmo estratégico) como da inevitável reprodução de padrões hegemônicos excludentes; 3) o voluntarismo necessário para amplificar abordagens epistemológicas subalternizadas de modo que elas possam se tornar mais pervasivas.</p><p> </p><p>Epistemologies for Conviviality or “Zumbification”</p><p>Inspired by Frantz Fanon’s thought, this paper is a diagnostic of the present time, enacted as a “psychotic reaction” that melts together different scriptural registers to advance the notion of conviviality as a space of analytical experimentation, where inequality and difference share the condition of conceptual isonomy. The experiment performed in this article tries to accomplish this goal by exploring the vernacular repertoire of the Brazilian junction of an afro-indigenous Atlantic. Its analytical idea, zumbification, is the sketch of an epistemological subject-position, whose labor consists in a kinesics of (at least) three movements: 1) the situatedness needed for making political demands; 2) the decenteredness necessary for attenuating the harmful effects of (even strategic) essentialism and the unavoidable reproduction of hegemonic exclusionary patterns; 3) the willfulness required for amplifying subalternized epistemological approaches, so that they may become more pervasive.</p><p>Capoeira | Conviviality | Epistemology | Post-colonial theory | Zumbi</p>

Cannabis points to the synaptic pathology of mental disorders: how aberrant synaptic components disrupt the highest psychological functions

Cannabis can elicit an acute psychotic reaction, and its long-term use is a risk factor for schizophrenia. The main active psychoactive ingredient ∆9-tetrahydrocannabinol (Δ9 -THC) activates cannabinoid 1 (CB1) receptors, which are localized to the terminals of glutamate and GABA neurons in the brain. The endogenous cannabinoids are involved in information processing and plasticity at synapses in the hippocampus, basal ganglia, and cerebral cortex. Exogenously applied CB1 receptor agonists disrupt neuronal dynamics and synaptic plasticity, resulting in cognitive deficits and impairment of the highest psychological functions. Various other pro-psychotic drugs, such as ketamine and methamphetamine, exert their effects in the same microdomain of synaptic spines as Δ9 -THC. Additionally, many of the most robust findings in psychiatric genetics include components that localize to dendritic spines and have important roles in information processing and plasticity.

“Bouffée Délirante” Induced by Meditation

IntroductionMeditation is frequently applied in Western as well as non-Western countries for different purposes; we know little about adverse events. The symptomatology of a meditation-related psychosis appears to show similarities with that we call “bouffée delirante”.MethodsA female patient is described who developed an acute and transient psychosis with polymorphic symptomatology after meditating (Bikram-yoga). We made a literature search for psychotic states related to meditation.ResultsThere are some case reports of psychosis disorder induced by meditation. Some cultural syndromes like Qi-gong appear on DSM-IV as psychotic reaction. In this case, the syndrome is not culture bound.ConclusionsMeditation can act as a stressor in vulnerable patients who may develop a transient psychosis with polymorphic symptomatology (confusion, pananxiety, mood swings and mood dystonic psychotic symptoms) with a short duration.Disclosure of interestThe authors have not supplied their declaration of competing interest.
