Any attempt to relate anthropological, botanical, medical, chemical, historical, and geographic information about 91 hallucinogenic plants in pages of text, with an equal number of photographs, maps, and art reproductions, is bound to be unsatisfying, if not unsettling.

Language: English Spanish French. This review focuses on recent brain imaging and behavioral studies of sensory gating functions, which assess similarities between the effects of classic hallucinogens eg, psilocybin , dissociative anesthetics eg, ketamine , and entactogens eg, 3,4-methylenedioxymethamphetamine [MDMA] in humans. Serotonergic hallucinogens and psychotomimetic anesthetics produce overlapping psychotic syndromes associated with a marked activation of the prefrontal cortex hyperfrontality and other overlapping changes in temporoparietal, striatal, and thalamic regions, suggesting that both classes of drugs act upon a common final pathway. Together with the observation that both hallucinogens and N-methyl-oaspartate NMDA antagonists disrupt sensory gating in rats by acting on 5-hydroxytryptamine serotonin 5-HT 2 receptors located in cortico-striato-thalamic circuitry these findings suggest that disruption of cortico-subcortical processing leading to sensory overload of the cortex is a communality of these psychoses. In contrast to hallucinogens, the entactogen MDMA produces an emotional state of positive mood, concomitant with an activation of prefrontolimbiclparalimbic structures and a deactivation of amygdala and thalamus.

Brain mechanisms of hallucinogens and entactogens

A hallucinogen is a psychoactive agent that often or ordinarily causes hallucinations , perceptual anomalies, and other substantial subjective changes in thought , emotion , and consciousness that are not typically experienced to such degrees with other drug classifications. The common classifications for hallucinogens are psychedelics , dissociatives and deliriants. Although hallucinogens all can induce altered states of consciousness with some overlap in effects, there are quantifiable as well as vast qualitative differences in the induced subjective experiences between the different classes of hallucinogens due to differing and distinct pharmacological mechanisms. The word hallucinogen is derived from the word hallucination. Leo Hollister 's five criteria for establishing that a drug is hallucinogenic were as follows: [3] [4]. This definition is broad enough to include a wide range of substances with different effects and characteristics. Although hallucinations are a common symptom of amphetamine psychosis , amphetamines are not considered hallucinogens as the hallucinations are not a primary effect of the drugs themselves.

 Линейная мутация… - еле выдавил Стратмор. - Я знаю. Коммандер медленно поднял голову. - Файл, который я скачал из Интернета… это был… Сьюзан постаралась сохранить спокойствие.

 Не может быть, чтобы Грег Хейл был гарантом затеи Танкадо. Это полный абсурд. Танкадо ни за что не доверился бы Хейлу. - Коммандер, - напомнила Сьюзан, - Хейл однажды уже чуть не угробил нас - с Попрыгунчиком.

Конечно, он должен был проверить все показатели, но единственная цифра, которая по-настоящему всегда интересовала директора, - это СЦР, средняя цена одной расшифровки. Иными словами, СЦР представляла собой оценочную стоимость вскрытия ТРАНСТЕКСТОМ одного шифра.

 Прости меня, - сказал он, стараясь говорить как можно мягче.  - Расскажи, что с тобой случилось. Сьюзан отвернулась. - Не имеет значения. Кровь не. Выпустите меня отсюда.

Скорее всего Северная Дакота попал в ловушку. Стратмор опустился на колени и повернул тяжелый винтовой замок. Теперь крышку не поднять изнутри. Подсобка компьютера надежно закрыта. Ни он, ни Сьюзан не услышали тихих шагов в направлении Третьего узла. ГЛАВА 60 По зеркальному коридору Двухцветный отправился с наружной террасы в танцевальный зал. Остановившись, чтобы посмотреть на свое отражение в зеркале, он почувствовал, что за спиной у него возникла какая-то фигура.

 - Он поднес телефон к уху и рявкнул: - Коммутатор.

Нет, решила. Конечно. Хейл продолжал взывать к ней: - Я отключил Следопыта, подумав, что ты за мной шпионишь. Заподозрила, что с терминала Стратмора скачивается информация, и вот-вот выйдешь на. Правдоподобно, но маловероятно.

Он перевел взгляд на слова, нацарапанные на ее руке. Она смутилась. - Боже, вы, кажется, сумели прочесть. Он посмотрел еще внимательнее. Да, он сумел прочитать эти слова, и их смысл был предельно ясен.

Офицер подошел к столу. Кожа на левой руке загорелая, если не считать узкой светлой полоски на мизинце. Беккер показал лейтенанту эту полоску. - Смотрите, полоска осталась незагорелой. Похоже, он носил кольцо.

Through formal and iconographic analyses of ceremonial paraphernalia, this paper shows that the primary ideologies of the cultures of this region involved the use of several psychoactive plants.
