Summary
Temporary amygdala signal reduction fundamentally alters resting-state functional connectivity in the brain, profoundly impacting cognition and perception. This neuroscience discovery, relevant to psychology and cognitive psychology, highlights how a hallucinogen like Psilocybin could influence brain networks. Understanding these neurotransmitter receptor influence on behavior mechanisms, perhaps through chemical synthesis and alkaloids, is crucial for psychedelics and drug studies. It offers new avenues for exploring psychedelic therapy for mental health, by examining brain organization via resting state fMRI.
Abstract
Our findings suggest that temporary amygdala signal attenuation is associated with mechanistic changes to resting-state network connectivity. These changes are significant for altered cognition and perception and suggest targets for research investigating the efficacy of psychedelic therapy for internalizing psychiatric disorders. More broadly, our study suggests the value of quantifying the brain's hierarchical organization using effective connectivity to identify important mechanisms for basic cognitive function and how they are integrated to give rise to subjective experiences.
