So are these people genetically different from you. Well quite probably and it is not because they are full blood aboriginals from Alice Springs but because they are dancers. Prof. Richard P. Ebstein of Hebrew University of Jerusalem has found genetic differences in the serotonin transporter and arginine vasopressin receptor 1a genes in studies of 85 dancers and advanced dancing students.

Naturally the audience of The Green Man will be familiar with the neuroscience that underlies serotonin transporters and arginine vasopressin receptors, however to lubricate the synapses, serotonin transporters regulate the level of serotonin, a brain transmitter that contributes to spiritual experience and vasopressin receptors have been shown in many animal studies to modulate social communication and affiliative bonding behaviors.

The dancer "type," says Ebstein, clearly demonstrates qualities that are not necessarily lacking but are not expressed as strongly in other people: a heightened sense of communication, often of a symbolic and ceremonial nature, and a strong spiritual personality trait.
