In the past few decades scientists have discovered a huge number of new facts regarding to the operation of the nervous system. A lot of them fit well into the upper right quadrant of the AQAL system. Some of these are described in the presentation.

On the successive Wilberian levels, new structures appear in the brain and different neuromodulators (hormones) influencing the quality of brain function become dominant at different stages of development. The polyvagal theory focuses on the lower levels, as a reliable neurological base is necessary for the healthy development of the brain. And neuroplasticity, one of the most amazing features of our brain, gives us the opportunity to consciously move up on the ladder, even toward transpersonal stages.
