How We Make Decisions

The frontal lobe is a region of the cerebral cortex of the brain that is responsible for decision-making, problem solving, and planning. Researchers have now discovered the specific areas of the frontal lobe that control abstract and concrete decision-making. The front portion of the frontal lobe handles abstract decisions and the back portion handles concrete decisions.

For example, if you had an idea that you wanted to bake some cookies, the decision process would start at the front portion of the frontal lobe. As you begin to determine the actions involved in making the cookies, a more concrete decision, the back portion of the frontal lobe would be involved. Understanding exactly how this part of the brain works could be very important to finding new treatments for strokes and other brain disorders.
