迷幻药可能通过破坏高级关联皮层控制自下而上的感觉信号的方式来改变意识状态。通常在受控实验室环境中对参与者进行单独的致幻药物研究。在这里,我们通过 40 种神经递质受体亚型的棱镜探索了 6850 个关于 27 种药物的自由形式推荐中的单词用法,然后通过侵入性组织探针的基因转录水平将其映射到大脑中的三维坐标。尽管个体间差异很大,但我们的模式学习方法描述了药物引起的意识变化如何与受体密度代理的皮层范围解剖分布相关。每个发现的受体体验因素都跨越更高级别的关联极和感觉输入极,这可能与之前报道的大规模网络中层次秩序的崩溃有关。通过共同分析许多精神活性分子和数千种药物体验的自然语言描述,我们的分析框架找到了潜在的语义结构并将其直接映射到大脑。自然语言处理工具挖掘了有关 27 种不同致幻药物的 6850 个现实世界叙述。
Psychedelics probably alter states of consciousness by disrupting how the higher association cortex governs bottom-up sensory signals. Individual hallucinogenic drugs are usually studied in participants in controlled laboratory settings. Here, we have explored word usage in 6850 free-form testimonials about 27 drugs through the prism of 40 neurotransmitter receptor subtypes, which were then mapped to three-dimensional coordinates in the brain via their gene transcription levels from invasive tissue probes. Despite high interindividual variability, our pattern-learning approach delineated how drug-induced changes of conscious awareness are linked to cortex-wide anatomical distributions of receptor density proxies. Each discovered receptor-experience factor spanned between a higher-level association pole and a sensory input pole, which may relate to the previously reported collapse of hierarchical order among large-scale networks. Coanalyzing many psychoactive molecules and thousands of natural language descriptions of drug experiences, our analytical framework finds the underlying semantic structure and maps it directly to the brain. Natural language–processing tools mine 6850 real-world narratives about 27 different psychedelic drugs.
