The trope of viewing a cinematic montage as a diagnostic or therapeutic tool appears in numerous films including such disparate works as The Parallax View (1974), A Clockwork Orange (1971) and The Game (1997). In all cases, the viewing subjects are connected to biofeedback or neurofeedback mechanisms that record physiological or neurological responses. A parallel, non-cinematic procedure is followed in Eternal Sunshine of the Spotless Mind (2004), where functional MRI imaging is used to map the location of memories in the brain in order to later eradicate the memories themselves in order to get over a failed relationship.
