Autonomic Nervous System States

Through the process of evolution the mammalian ANS has a primary repertoire of  3 principle states. These states functionally and adaptively shift according to how safe we feel at any given moment. The mechanism involved in shifting these states (see neuroception ) occurs beneath the level of conscious awareness. These states form an underlying neurophysiological foundation for our feelings and emotions. In reality, these states are not always independent, but may interact to form hybrid states, which support a continuum of behavioral reactions ranging from quiescence to mobilized actions within both safe and threatening contexts.
