Core - In the old MPD model (pre-2000), all plurals begin as one person, the core, who splits off parts of herself. This is not the experience of many plurals, especially those whose systems did not originate from trauma. However, some systems really do have one or more cores from whom everyone else came. The Troops (Truddi Chase) had a "first-born child" who was divided into two cores. They described the development of new people as birth.</p>

'Core' might be a useful term for medians, to describe the central person (if any) in their system. In systems that do have a core, the core and the presenting self or selves -- the one(s) people are most likely to see -- are not necessarily the same person. The core is also called the 'birth person' or the 'original' or 'first-born child'. We've known two groups who called this the "base". (Psychiatric)</p>
