Resumen
Los psicodélicos, como la psilocibina, activan de manera única los receptores de serotonina dentro de las células del cerebro. Esta acción intracelular difiere de cómo el cuerpo
Área de la Ciencia:
- La neurociencia
- Farmacología
Sus antecedentes:
- La serotonina es un neurotransmisor clave que regula el estado de ánimo y la cognición.
- Los antidepresivos tradicionales se dirigen principalmente a los receptores extracelulares de la serotonina.
Objetivo del estudio:
- Para aclarar el mecanismo único de acción psicodélica.
- Para investigar el papel de los receptores intracelulares de la serotonina.
Principales métodos:
- Utilizando técnicas avanzadas de biología molecular.
- Analizando la interacción de los compuestos psicodélicos con los subtipos de receptores específicos.
Principales resultados:
- Los psicodélicos se unen a los receptores de serotonina ubicados dentro de la célula.
- Estos receptores intracelulares no se activan directamente por la serotonina endógena.
Conclusiones:
- Los psicodélicos activan una vía de señalización distinta en comparación con las drogas serotoninérgicas convencionales.
- Este mecanismo intracelular puede explicar los efectos profundos y duraderos de los psicodélicos.

207
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

01:27Hallucinogens and Psychedelics
231
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...
