The Brain Exercise:
This puzzle uses planning and reasoning skills. You read the statements and then must develop a plan to solve the problem using your reasoning skills. These skills are found predominantly in your prefrontal cortex. This area of your brain is responsible for executive functions such as planning, structuring, and evaluating voluntary, goal-directed behavior, i.e., activities requiring the constant comparison of planned acts with the effects achieved.
