What is Neuro-Emotional Technique?

Neuro Emotional Technique (NET) is 

a mind-body stress-reduction technique used to identify and release unresolved emotional stresses that are "stuck" in the body. Developed in the 1980s by Dr. Scott Walker, a chiropractor, it is based on the concept that emotional trauma can create "Neuro Emotional Complexes" (NECs)—patterns of physiological, neurological, and emotional responses that stay in the body, potentially contributing to physical or emotional pain.
