The hammer is designed to address just this type of situation. It installs beliefs, thoughts, attitudes or ideas into one side of the brain at a time. All that needs to be done to correct an imbalance is to find out what kind of thoughts produce success, then install those good thoughts into both sides of your brain. Take a look at how the various areas communicate with one another. Facilitation means that communication is achieved by one area increasing the activity of the other.
Inhibition means that communication is achieved by one area decreasing the activity of the other.
Communication within hemispheres is largely accomplished through facilitation, and communication between hemispheres is largely accomplished through inhibition. In this way the two sides of the brain tend to moderate each other. If one side of the brain has too much strength it can squelch the other side. When this happens you have only half of the brain power you are entitled to. Again, the answer is to install positive thoughts and beliefs into both sides of the brain.
