Node Isolation Theory*
and the
Eye-Zone Differential Technique*

Node Isolation Theory posits that some trauma targets--especially in complex trauma and dissociation--are "undiffereniated" or multi-layered, possibly reflecting the activation of multiple trauma nodes or ego states. Processing (phase 4) becomes ineffient or ineffective, with problematic looping, blocking, confusion, dissociative "cross-talk" or rapid state shift. The strategies taught endeavor to isolate the node at the epicenter of the traumatic event.

This three-part strategy includes the Eye-Zone Differential Technique, a method for isolating the traumatic node with multiple titration and resourcing options for safe and efficient processing of highly disturbing material.
