When you have to choose one over the other what part of brain is at work?

The prefrontal cortex (PFC) is the part of the brain that is most involved in making decisions. The PFC is located at the front of the brain, just behind the forehead. It is responsible for a wide range of cognitive functions, including planning, decision-making, and impulse control.

When you have to choose between two options, the PFC weighs the pros and cons of each option and then makes a decision based on the information it has. The PFC also takes into account your past experiences and your current goals when making decisions.

The PFC is not the only part of the brain that is involved in decision-making. Other brain regions, such as the amygdala and the hippocampus, also play a role. However, the PFC is the most important brain region for making decisions.

If you have damage to your PFC, you may have difficulty making decisions. You may be more impulsive and less able to control your emotions. You may also have difficulty planning for the future and setting goals.
