Three Brains are Better than One

To begin to understand how the human brain processes information during our daily interactions you have to break down the human brain so it’s nice and simple to understand.  I remember the first time I saw an actual human brain,  and the thing I remember most is that it looked nothing like the clean images and drawings from the text books. It actually looked like a grayish mess, but once we got to slicing and dicing it began to make sense of what was what. Our lesson today is nowhere near as complex, hopefully it’s more intriguing.

The Reptilian Brain

The reptilian brain is a very primitive organ. It’s called the reptilian brain because it has been around for over 450 million years and is actually still present in reptiles today. This is the first part of your brain to develop. The reptilian brain or the “old brain” is responsible for you unconscious processes. It controls things like heartbeat and breathing. Think about it, have you ever had to focus to make your heart beat, or to make yourself breath (assuming you’re not having a panic attack). Of course not, these things just happen and that’s thanks to your old brain. It’s been said that the old brain is primarily concerned with your survival. The most recent research has shown that the old brain plays a major roll decision making. The old brain actually decides “yes” or “no” in response to a situation or stimuli. Pretty neat stuff huh? We’ll expand more on the old brain at a later time.

The Middle Brain

Through human evolution we developed a brain on top of our first brain. This brain, the middle brain, is a little more complex than the first brain. From a social neuroscience perspective the middle brain is primarily concerned with emotional processing. Emotions are vital to understanding and communicating in social interactions and play a crucial role in our behaviors and actions.

The New Brain

The new brain is what makes our species so unique. No other animal has a brain like ours and that’s because of our new brain, also commonly referred to as the neo cortex. This brain is responsible for higher level thinking. It allows us to think in abstract and hypothetically as well as perform rational thought. Studies have shown that this part of the brain continues to grow and develop until the age of 24. This is what separates us from other animals and makes humans so unique.

Three Brains Become One

So lets tie this all together. The reptilian brain decides, the middle brain processes emotions, and the new brain thinks. When confronted with a stimuli all of these processes from your three brains work in concert to achieve an end result.  This is the process that your brain works when confronted with almost any situation. Of course you’re largely unaware of what’s going on, but social neuroscience aims to give you the understanding of how you perceive and communicate. The knowledge of the social perception process can make a big difference in understanding your actions and emotions. Now that we’ve laid something of a base I hope we can begin to really explore this dynamic process through some example interactions.

If this sounds like something you’d like to learn more about I recomend picking up the book NEUROMARKETING written by Patrick Revoise & Christopher Morin. This book looks at how the brain makes decisions and the best way to communicate to the old brain. It’s a terrific read and much of this post was inspired by the book’s breakdown of the brain.
