Introduction functional magnetic resonance imaging fmri is well established as a method for the detection and delineation of regions of the brain that change their level of activation in response to specific experimental conditions. The present study uses resting state functional magnetic resonance imaging fmri to test whether distinct functional connectivity patterns like those observed in animal studies can be detected across three amygdala subdivisions laterobasal centromedial and superficial. In conclusion recent resting state fmri studies examining functional connectivity between brain regions have revealed new fundamental insights in the organization of the human brain and provide a new and promising platform to examine hypothesized disconnectivity effects in neurologic and psychiatric brain diseases. The ability to map multiple distinct striatal circuits in a single study in humans as opposed to relying on meta analyses of multiple studies is a principal strength of resting state functional . The results illustrate that resting state functional connectivity is not static and that rsns can exhibit nonstationary spontaneous relationships irrespective of conscious cognitive processing
