Is There a Difference Between Right and Left Brain?

We have been taught traditionally that the right half of the brain is our emotional brain. We have emotions in both hemispheres, and we have thinking cognition in bothhemispheres. And so i'm asking people to consider that there is a difference in the emotional system of the right brain and the emotionalsystem of the left brain based on the anatomy of the brain. If i truly want to influence myself and my behavior and my emotions and thoughts at the at their core level, and i want to fix the system, i have to go to the cells.
