Neuroscience of Curiosity and Alzheimer's

So the last time when we talked here about two years ago, we talked about my first book,

The Indoctrinated Brain, and there I show that the growth of these new nerve cells is

important that we are open for new ideas, for new memories, that we learn, that we reflect

about things, but also that we are curious.

These new nerve cells are the neuronal correlate for curiosity.

Human curiosity is dependent on the production of new nerve cells in the hippocampus.

So we are more curious when we have a dog because we produce more oxytocin.

And what we talked about two years ago was that the spike protein produced by the mRNA

that is injected in this weird program is doing just the opposite.

The spike protein activates neuroinflammation in the brain, and we have to talk about neuroinflammation

today because lithium is the antidote.

Actually, we talked about this two years ago.

So if neuroinflammation occurs and it's chronic because the spike protein doesn't go away,

then the neuroinflammatory process activates the production of interleukin-1, interleukin-6,

TNF-alpha, all pro-inflammatory cytokines.

And the main reason that they are produced is to signal the immune system there's some

damage in the brain, but a side effect is, and that's physiological, is that it shut

down the hippocampus.

They shut down the production of new nerve cells in the hippocampus.

In the short run, this is good because it creates a behavior that is, you are not curious

when you are sick.

you want to go back, you don't want to socialize, that protects others if you're really sick.

You are not curious when you're sick. That is true.

Yeah. So that is the result in the short term. But if it's chronic, if chronically there's a

shutdown of the production of new nerve cells in the hippocampus, then the consequences are

depression, anxiety, and in the long run, it's Alzheimer's. So they actually identified after

the mRNA injections after a few months that the Alzheimer rate went up in a study published in

Seoul in South Korea. It was, I think, published in 2023. And I predicted this already in my book,

The Indoctrinated Brain, I said the mRNA injection will increase Alzheimer's.

So Alzheimer's... And it has.

And it has. It was published in a Korean study. So all the predictions were correct,

unfortunately. Well, it was good for me because I like it when I'm correct in my predictions,

but it's not good for the human world. So the humanity hinges on the ability of the

hippocampus to produce new nerve cells. That is the key to humanity. If we reduce it to

one function of the brain is that being human is that we are curious, that we can reflect,

that we have what I call psychological resilience. Because even if you're curious,

but you fear going a new path, then it doesn't do any good. Curiosity has to be like two sides

of a coin. On the one side, you have curiosity. On the other side, you have the psychological

resilience. And this coin with these two sides is based neurologically on the function of the

production of new nerve cells. So you need new nerve cells to be curious, to have resilience.

Actually, all drugs that are on the market that are against depression have one key feature,

they activate the production of new nerve cells in the hippocampus.

I'm not saying you have to take them, but this is their function.

So they are essentially antidepressants based on the function that they produce in the nerve

cells in the hippocampus.

And being human, in my opinion, means that you are able to produce these cells because

then you are curious, you are interested in the opinion of other people, you can reflect

on the opinion of other people.

There's another feature these cells represent, in my opinion, I outlaid it in my book, is

that they confer something what I call, not empathy, but the right word is rational compassion.

I think it's the right term, rational compassion.

So when we are empathic, we immediately act on something, we see something, we act, this

person is suffering, we act.

But rational compassion is more like, if I do something, what does it mean for the other

person?

People who are not even outside, not inside this room, people outside in other countries,

what do my actions do to these people?

For this, empathy is not the right function in our brain.

This is what Kahneman, who got the Nobel Prize about system one, system two, 2002, a psychologist,

called system one, it's a reflex.

Empathy is kind of a reflex.

But rational compassion is something that requires thinking.

Thinking about putting yourself in the shoes of others, maybe people you don't even see.

Seeing the world out of the eyes from other people.

And all these functions are based on the production of new nerve cells in the hippocampus.

So if you shut down the production of new nerve cells in the hippocampus,

people lose essentially the ability to be human.

They lose themselves.

Yeah, they lose themselves.

And the ultimate losing of oneself is having Alzheimer's,

which actually is the ultimate result of having a lifelong shutdown of the production of new nerve cells.
