Summary
Remarkably, LSD significantly changes how the brain's early visual areas communicate, even when eyes are closed. Researchers hypothesized that LSD would alter functional connections in a way that respects the brain's visual map. Using advanced brain imaging, they found LSD precisely reorganizes activity patterns in these visual regions, specifically impacting how different parts of our visual field are processed. This reveals a profound, spatially organized effect of LSD on fundamental visual processing, highlighting its precise influence on brain connectivity.
Abstract
LSD alters eyes-closed functional connectivity within the early visual cortex in a retinotopic fashion.
