Reptilian brain is the oldest brain and has survival instincts, which were developed when we used to live in jungles.
Neo-cortex deals with logic and higher thinking skills.
Now the limbic brain or the mammalian brain is responsible for the emotions and memory. Our body expresses its emotions through body language and micro-expressions.
So let's talk about them in detail:
It is our oldest brain and was developed over 100 million years ago. It has survival instincts. Every stimulus or piece of information has to first go through the reptilian brain before it reaches limbic brain or neo cortex.
characteristics of reptilian brain is :to dominate, to be dominated, fear, aggression, praise, submission, mating or simply(kill it, eat it or mate with it).
If there is any danger it reacts spontaneously and it in these situation once alarmed our body switches to freeze, flight and fight response which I will discuss in the next chapter.
If there is something not interesting it ignores simply ignore it and if there are some complications it avoids it. So we must learn to bypass the reptilian filter so that the information can be processed in neo-cortex and the limbic brain. This becomes very critical if you are pitching anything.
Let’s take an example of a sales person, the pitch is failed the moment it enters in the reptilian brain if it is threatening in any way. So the information has to be sandwiched in between different layers to bypass the reptilian filter. And to do that, that piece of information should have concrete facts, non-threatening in every way and should offer some unique choices.
The main problem is that most of the information is initially processed by this part of the brain which is why all the TV commercials are focused on pleasing our reptilian brain so that whenever we see the product, the first reaction is to buy.
So first we have to calm down the reptilian brain in order to pass the information to neo cortex.
This part of the brain is responsible for memory and emoti0ns.Usually actions taken by reptilian brain is governed by limbic brain(such as freeze, flight and flight) as they all are interconnected and the possible reason for that is what we learn is stored in this part of the brain also known as mid or mammalian brain, most of our actions and reaction are the results of different experiences we had in the past which are registered in this part of the brain so when we encounter the same situation we have almost same kind of response and hence most of our human emotions are governed by this part of the brain.
Let's talk about fear, it is fair to say that almost every fear is learnt when we have some unfortunate or threatening experience it get registered in this part of the brain so when we encounter the same situation we react in a way so that it does not harm us and can be termed as a form of fear.
we should always let our neo cortex decide what to do in fear encounter rather than reptilian brain as neo cortex can think logically so we should learn to bypass the information to neo cortex to avoid panic.
Almost 76 percent of the brain is governed by neo cortex. It is the upper part of the cortex also known as newest brain.
It is responsible for higher order functions and logics such as language, motor response, sensory perception, spatial reasoning, thoughts etc. This is the intelligent part of the brain where stimulus is processed and analysed effectively.
