概括
N,N-二甲基三胺 (DMT) 改变了意识和大脑活动. 像Lempel-Ziv复杂度这样的神经复杂度指标显示,与主观经验的关联比以前认为的要弱.
科学领域:
- 神经科学是一个神经科学.
- 心理药理学 心理药理学
- 意识研究 意识研究
背景情况:
- N,N-二甲基三胺 (DMT) 是一种强烈的迷幻药,以其快速,深刻的意识和大脑动态变化而闻名.
- 支持这些迷幻诱导意识状态的精确神经机制仍然不完全理解.
- 现有研究表明神经复杂度指标可能与主观迷幻体验相关.
研究的目的:
- 研究DMT对主观体验和神经动态的剂量依赖作用.
- 探索特定的脑电图 (EEG) 特征与DMT中毒期间的实时主观体验之间的关系.
- 重新评估Lempel-Ziv复杂性的实用性,作为迷幻现象学的相关性.
主要方法:
- 一项重复措施,剂量依赖性研究,涉及19名参与者,以盲目,平衡的方式接受20毫克或40毫克的自由基DMT剂量.
- 收集脑电图 (EEG) 数据以分析神经动态.
- 使用时间体验追踪对主观经验的实时评估.
主要成果:
- 20毫克和40毫克的DMT剂量都引起了主观体验尺寸的快速,显著的变化.
- 40毫克的剂量与更强烈的视觉幻觉和情绪体验有关.
- 与伦佩尔-齐夫复杂性相比,振荡性α功率和顺序的度与主观体验维度的关联更强.
结论:

CNS Stimulants: Psychedelic Agents
630
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
561
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.

Long-term Depression
3.0K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
