Summary

In "image B", this fMRIA type of neuroimaging. Neuroimaging is an approach that allows researchers to view areas of the brain that become active during behavioral events such as emotion, perception and cognition. It is part of the science of in psychophysiology. scan shows a distinct state switchingFull dissociation is when an alter switches with the alter currently in executive control, resulting in amnesia for that alter. (see executive control) {{Rp|4-6}} In full dissociation, there is complete amnesia between dissociated states, which is a {{Rp|228}} criteria for a diagnosis of dissociative identity disorder in the DSM-5. {{See also| Dissociation}} with an other distinct state, which is only possible in DID, because this is the only disorder with two or more distinct states. "Image A" shows three less than distinct states which are the parts that manage "unprocessed trauma," and react to it with vehement emotion. This is obviously an fMRI scan of DID since it shows there are two distinct states and three less than distinct states. In OSDD fMRI scans reveal only one distinct state is possible, and it switches with less than distinct states randomly, and the distinct state also switches in response to a "triggerA reactivating stimulus in trauma disorders. A stimulus in the present which is a reminder of a part of a traumatic [[memory]], which can cause the part of an individual that hold the trauma (EP) to feel as if it is reliving past trauma experience. {{Rp|166-186}} Also known as a trauma trigger.." In contrast to DID, every single state can literally be conscious (lit up) at one time, but in response to a trigger, all but one state will leave consciousness, which is again in contrast with DID. In PTSD there is only one less than distinct state and one distinct state, and both stay conscious until a trigger causes the less than distinct state to respond, (flashbackA flashback is a reactivated traumatic memory experienced as intrusive thoughts, feelings, or images associated with past trauma, but lacking a sense of being from the past. {{Rp|30}} It is experienced by the state referred to as the EP. {{See also | Grounding techniques}}, fear, anxiety or other like symptom) and when it does the distinct state leaves consciousness. In the complex version of PTSD there are always two less than distinct states, and one distinct state. The less than distinct states are polarized, staying together, with both always conscious at the same time, but otherwise behave the same as simple PTSD. BPD involves one distinct state and it's always conscious until the individual is in distress, and then two less than distinct states show up together, but unlike C-PTSD these less than distinct states do not take over consciousness. The distinct state always remains with them. There are no flashbacks or other symptoms caused from unprocessed trauma events in BPD like there are in all the other disorders mentioned so far, but there are other dissociative symptoms.

PLOSone: Dissociative Part-Dependent Resting-State Activity in Dissociative Identity DisorderPrior to the DSM-IV, dissociative identity disorder was known as multiple personality disorder, which was from 1980-1994. The International Classification of Diseases,(ICD) still uses this label, even though the ICD-11 is expected to change it. The term is misleading. No one can have more than one personality, nor is the disorder a personality disorder. {{See also| Multiple Personality Disorder}}: A Controlled fMRI Perfusion Study by Yolanda R. Schlumpf, Antje A.
