LSD veraendert Hirnschaltkreise so, dass Wahrnehmung und Denken staerker verschmelzen und die Grenzen zwischen inneren Gedanken und aeusseren Reizen unschaerfer werden

LSD alters large-scale brain circuitry in ways that make perception and thought less distinct. Brain regions that usually separate sensory input from internally generated cognition become more interconnected, which may help explain why people under LSD experience vivid imagery, altered meaning, and a blurred boundary between what is seen and what is imagined. These effects are tied to changes in communication across functional brain networks rather than to a single isolated region. Stronger cross-talk between systems involved in attention, sensory processing, and higher-order cognition suggests that LSD increases neural flexibility while weakening ordinary filtering and segregation. This pattern matters because it links subjective psychedelic effects to measurable brain dynamics. The findings support a mechanistic account of how LSD can reorganize conscious experience and may inform broader research on perception, self-processing, and psychiatric treatment models.
