Functional magnetic resonance imaging, or fMRI, has become a standard tool to visualize how the brain processes information.

In a seemingly contradictory finding, research that used functional magnetic resonance imaging, or fMRI, to study brain responses to disgusting humor did not find a pattern of brain activity that was distinct from plain disgust.

Research into the use of fMRI scans to investigate internet addiction is currently limited and the studies had small adolescent samples.

These findings may also affect current approaches to interpreting fMRI scans, which measure changes in blood oxygenation within brain structures as they are activated.

So far, this is the first time that such approximation of arousal levels using fMRI was attempted in psychedelic research.
