Neuroscience will enlighten what is behind our decisions

Advances in technology have enabled a better understanding about the brain and its work principles. In this sense EMG technique examining electrical activities of human brain presented the question “Is there any freewill?” to the world of science.

It was revealed by the studies that an electrical activity is performed in our brain before decision-making process. This has opened the door slightly to scientists about pre-knowing a decision, which has come up in mind with the question ‘Is there any freewill?” Nobel prize winning economist Daniel Kahneman had enlightened this process by reporting that first and second parts of the frontal lobe are effective in our decision-making processes. Then in such case, will all information regarding people’s all decision-making processes be wiped?

Prof. Dr. Uğur Batı, Vice President of Interdisciplinary Brain Research Society and Faculty Member at Nişantaşı University, said, “In no uncertain terms, all data indicate that we live minimum 98% of a day automatically and make our decisions accordingly,” in the 3rd Neuroscience Congress where nearly 900 scientists attended, and which was organized by Interdisciplinary Brain Research Society (DABAD), and hosted by Nişantaşı University.


“Brain has a comfort system and prefers the easiest. Difficult decisions are made only with willpower.”, continued Prof. Dr. Uğur Batı . He also added as follows: 

“The first part of the frontal lobe is managed by brain’s limbic system. Limbic system is right below the cortex covering the upper part of the brain. This first part makes quick decisions, and it is automatic. It does not think longer and make calculations. It tends to neglect things and does not care you. For that reason, this part is responsible for the things not requiring any calculations. A lot of daily routines are managed by this part. For example, driving a car or eating is some of them. You do not think which hand you will use to take the food or if you need to put the food in your mouth or nose when you eat. Once brain learns them, it turns them into automatic tasks. It learns quickly and never asks you again. We can call this part as carnal brain, which means it is quick and does not think. We need to make many of our decisions in life quickly and without thinking, which carnal brain performs.”


Prof. Dr. Uğur Batı said that the second part of the frontal lobe is managed by prefrontal cortex, and this part is responsible for making the best decision, and added “Decisions transferred to this part need concentration, energy, information and mostly effort. For example, the question “51x18=?” is transferred to this part because the first part cannot handle it. More complicated math and calculation problems are related to this part of the brain. People we call “intelligent” in daily life are the ones with this part of their brains performing well. Many of our decisions in our lives are managed by this part of the brain. Decisions about schools, cars or choice of computer need seriousness and effort. We can call this system of the brain conscientious brain. Conscience wants to think, but does not want to be wrong. Intelligence questionnaires known as IQ measures the capability of this part of the brain.
