Over the course of the past several decades there have been many models of how the brain works. We will briefly present some of these approaches. The neuroscience field has experienced enormous growth in the past 3 decades due to the development of modern medical technologies.
The models presented below provide an overview of how conceptually the field has grown. Dr. Thornton’s research provides evidence that the holographic model is the most appropriate model to employ.

The functional model looks at the brain in terms of what it does, such as the left hemisphere is the analytic side of the brain while the right hemisphere is responsible for spatial and emotional processing. These type of descriptions, albeit having some validity, have limitations in their simplification of functions.
