Gaba vs Serotonin in Neurotyping


#1

Hi Coach,

In neurotyping most of the focus, I feel, has been on the neurotransmitters that excite the nervous system (dopamine, adrenaline, etc) but I’ve read less about the ones that bring someone down and their effects. Does the neurotransmitter that brings a person down vary inside of types (eg, you have a 1b that relies more on serotonin to relax and one that relies more on gaba) or would all 1b’s be one or the other? And would this have a large effect on personality, at least at rest? And if they differ inside of a type, would it be beneficial to try to figure out which one you rely on? Curious to hear what you’ve found

Interesting, so with 2a’s then is GABA dominant more like on/off like a light switch almost, like more introverted when not activated? And could a GABA inhibitory dominance cause 1a or 3b to be much more introverted when they feel “off”?

The 2A is normally fairly balanced which is why it is so adaptable. They adjust their behavior to the person they are with or to the situation. They easily mimic others. Basically they have a little bit of everything (that’s why they are the middle type) which allows them to play any role. They are jack of all trades but master of none.

NOW, to quote one of my friends who is a one of the smartest functional medicine specialist I know “Everybody has a GABA problem”. The 2A is less affected than a 2B when that happens because they can more easily rely on serotonin than the 2B.

Normally the more easily adaptable someone is, the more efficient is his serotoninergic system. So a Type 1A and 3 have lower serotonin activities: these 2 types are extremely rigid. The 1B has the highest serotonin level (which is why a lot of 1B athletes are very lazy and laid back most of the time and are easy to get along with; but when the heat is on, they are machines). The 2A is similar in that they also tend to be lazier unless the heat is one. Both types are more prone to procrastinating.

The 2B has the lowest GABA level of all the types. That’s why they are so emotional. What is the connection?

Glutamate (an excitory neurotransmitter) is the precursor to GABA. As such it is pretty much impossible to have a high level of both since glutamate is converted to GABA. 2Bs have a very high level of glutamate. Here are the symptoms of high glutamate:

Social anxiety
Very emotional
Hypersensitivity to sensations
Tendency toward losing control of his thoughts, creating emotional scenarios
Open display of emotions
Easy addiction to anything making him feel good
Easily fall in love
Responds badly to failure (hard on himself)
Attracted by beautiful things
Loves shopping and buy by emotion
Rapid changes in behavior (from extreme joy to extreme sadness for example)

Which are pretty much all traits of 2Bs.

The 2B having high glutamate (that’s why they are so emotional) means that they are not efficient at converting glutamate into GABA; which is why they have the lowest GABA level.

So they have to rely more on serotonin to inhibit/calm down their CNS. The problem is that they don’t have a lot of it (not anywhere close the 1Bs). And since they have low GABA they easily deplete serotonin. This is the reason why 2Bs are more prone to binging out on sugar when they are stressed or down (to increase serotonin) and to depression.

The type 3’s rigidity is a fairly integral part of their neurotype, but I was under the impression 1a’s were a little more laid back? Or I am misunderstanding this line?


#6

Type 1B are laid back

Type 1A are super intense. They always want to do things their own way. They hate rules. They have a real hard time making compromises. They are on or off, black or white (there is no grey).

The best example of a 1A, and it is an EXTREME case of 1A = Donald Trump. Not all 1As are like Trump, he is an amplification of all the 1A traits. But you get the idea.

This makes a lot of sense actually…

Any advice on how to convince a 1A to follow a rule if they don’t want to/think it’s stupid? I’m a team captain and there’s a very high concentration of 1A wrestlers, and most are very bad at following rules (shocking, I know)

Thanks for the insight so far though. I’m trying to learn as much as I can so I can be an effective leader for everybody on the team, not just a specific type; so it helps a lot if I can understand underlying motivations for what they do. Would love to see an updated article about the science behind neurotyping-I find it super interesting and applicable
