For the first time, Tufts University biologists have reported that bioelectrical signals are necessary for normal head and facial formation in an all organisms (just in August 2012)! Watch this http://www.youtube.com/watch?v=ndFe5CaDTlI&feature=related. As Biodynamic Craniosacral Therapists, we have been aware of this information for quite some time due to the research and generous sharing of associate professor of anatomy and embryology at the University of Maasricht, Holland Jaap van der Wal: http://www.embryo.nl/ .
How this translates into Biodynamic Craniosacral Therapy: This bioelectric field is what organizes form all together. As an embryo we begin our formation very similar as a mineral by growing out into the world in a somewhat disorganized fashion. Then magically a bioelectric streak of light appears, creating a mid-line and the whole growth pattern of the embryo changes into something more organized. It becomes more organized by initiating the movements of our growing patterns into spirals. The folding of the embryo is because of the energetic field coming through, (as you can physically see in the video posted above).
