Related fMRI evidence comes from a study by Addis in which participants remembered person-location- object memories and also imagined events that might occur in the future, or might have occurred in the past, that consisted of person-location-object scenarios recombined from actual memories. All three conditions were associated with activity in the default network, but differences were also observed: activity in posterior visual cortices such as fusiform, lingual and occipital gyri and cuneus, as well as parahippocampal gyrus and posterior hippocampus, was preferentially associated with remembering actual events as compared with imagining future or past event
