CNS Stimulants: Psychedelic Agents

CNS Stimulants: Psychedelic Agents

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...

Hallucinogens and Psychedelics

Hallucinogens and Psychedelics

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.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

Area of Science:

Neuroscience
Artificial Intelligence

Background:

The serotonergic system regulates conscious perception.
Psychedelics, such as N,N-Dimethyltryptamine, offer a way to study this system.
Evidence suggests this system gates endogenous and exogenous information during conscious experience.

Purpose of the Study:

To explore the regulatory role of the serotonergic system in conscious perception.
To investigate the potential of generative deep neural networks in modeling psychedelic visual effects and underlying neural mechanisms.

Main Methods:

Utilizing two generative deep neural networks as models.
Analyzing the potential of these models to illustrate phenomenological visual effects.
Conceptualizing biological mechanisms of information gating in visual perception.

Main Results:

Generative deep neural networks can serve as a novel medium for illustrating psychedelic visual phenomena.
These models offer a framework for understanding how the brain gates sensory and internal information.

Conclusions:

Deep neural networks provide a valuable tool for studying consciousness and the effects of psychedelics.
Understanding information gating mechanisms is crucial for comprehending visual perception and conscious experience.
