Preliminary Report on the Effects of a Low Dose of LSD on Resting-State Amygdala Functional Connectivity
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.

Twenty healthy subjects underwent a within-subjects, double-blind, randomized trial to examine the effects of one low 'microdose' of LSD (13 micrograms) on resting-state functional connectivity and cerebral blood flow. Subjects received either the placebo or LSD dose, and participated in two fMRI scanning sessions seven days apart. Amygdala and thalamic connectivity were analyzed and mood questionnaires were collected. The LSD microdose increased amygdala seed-based connectivity with the right angular gyrus, right middle frontal gyrus and the cerebellum, while decreasing amygdala connectivity with the left and right postcentral gyrus and the superior temporal gyrus.
