A key theme here is the transduction between metabolism and electrophysiology — between our chemistry and our brainwaves. This is a key interface in both how brain problems are created, and how they may be reversed.
Here is a key paper I wrote on this topic in 2013, in Frontiers in Autism Research, pp. 515-556 (2014): Chapter 21: Translational Implications of a Whole-Body Approach to Brain Health in Autism: How Transduction between Metabolism and Electrophysiology Points to Mechanisms for Neuroplasticity
Earlier papers addressing these themes include:
