We recently employed resting state fMRI to identify fingerprints of cannabis use history and #cannabis intoxication in the whole brain human connectome.
Two distinct data-driven methodologies, i.e. network-based statistics (NBS) and connICA, were used to identify changes in functional brain connectomes collected during placebo and THC exposure in occasional and chronic cannabis users.
Whole-brain network approaches identified spatial patterns in functional brain connectomes that distinguished acute from chronic cannabis use, and offer an important utility for probing the interplay between short and long-term alterations in functional brain dynamics when progressing from occasional to chronic use of cannabis.
