Between different sensory integration. It's a hub for integration. And interestingly, actually, it's also involved in the self-other distinction. So we have a distinction of the land here, Dr. Peterson over there. And then... That's why we can't tickle ourselves. That's why we can't tickle ourselves, right?
But that part of the brain, if you zap that, sometimes the self-other distinction can break down. So you feel like you're merging into another person. So that's very interesting. So it has that function. It also has... connections to the frontal lobes, which is involved in obviously in empathy and seeing the perspective of somebody else.
So like a theory of mind, what is Dr. Peterson thinking right now? What is his agenda right now? What is his motives? So that ability is also involved. And this comes to a psychopathy point actually, because if you have the temporal parietal junction being involved in body construction.
So it's involved in self and constructing a body image, which is expanded in the rubber hand illusion, but also involved in seeing your perspective as well. So it's very dynamic.
Experiencing somebody else's perspective.
They don't look at eyes.
It probably could be trained. So I know Richard Davidson, he's done some studies looking at amygdala activation in autistic children, and they do have an amygdala that's dancing with activity whenever they look at eyes. So they have that, but it's not entirely known why. It probably has to do with the fusiform face area. So there's a region of the brain specialized for recognizing faces.
And so it has to do with that, but this is- Properly oriented faces only, right? Properly oriented faces, exactly.
It doesn't matter. Yeah, yeah. And to be frank, this area of the brain is also involved in dry classification of objects. So not only faces- Musical instruments? Probably. I think so. But it's more dry, so it goes like a guitar from a piano or something like that. It doesn't have that specification. To have specificity, you have to go higher up in the system.
So it has this more banal quality to it. And so obviously in visual processing,
you have a hierarchy of of of where it becomes more complex with each step of envision and then the highest so it goes then it goes to a point where you start classifying objects in the world that's the fusiform phase area and then after that you go to vernica which is more sort of meaning and purpose and then you go to things like the hippocampus which is involved in in things like memory uh so it goes from more simple stages of visual processing to
dry classification faces Dr. Peterson's from from Alex from Kim knowing different people So that's that's that part and then going to higher centers.
Right, exactly. They somehow don't attend to it, right? So they can draw a flower the whole day, but they only draw half of the flower. And you keep telling them and they say, well, I did my best, I'm drawing it, but they can't attend to that part of the brain. Right.
Mind you, the parietal lobes is involved in spatial orientation, knowing not only the body where it is in space, but also the spatial layout of the room, right? So it has that component. So it's a really strange disorder. And in order to understand how they are experiencing this at a subjective level is really critical. It's a mystery of sorts.
irrigation irrigation but before we go there i just want to so the parietal lobes and this and then superior parietal lobule another fancy name there right so just above the temporal parietal junction is specifically involved in creating a body image as well so the the tpj we talked about taking information from various sensory modalities and then and then whispering information to the
superior parietal lobule, this area just above it, it's a neighbor, right? It's involved in creating a subjective sense of a self, the feeling that I occupy this body and not somebody else's body, right? So when people have a stroke to that part of the brain,
As you mentioned, they will sometimes throw their hands out, say, this arm doesn't belong to me, it belongs to you, or it belongs to my dad, or it belongs to this person or that person. So literally, they will become delusional. You can play chess with them, you can have conversation, nothing, nothing is wrong. Otherwise, they're not delusional, they're not psychotic or anything like that.
But after they have the stroke affect this region of the brain, they will just say that this arm doesn't belong to me. Or sometimes they might even say, you might ask them, you say, well, they might deny the paralysis. So that's anosognosia, right? So you say, Joe, your arm is paralyzed. They'll say, no, it's not paralyzed. Well, then touch my nose, Joe. And they will say, okay.
And they will take the lifeless arm and lift it like this and say, I'm touching it, doctor. I'm touching it, literally taking it up like that.
So one way to approach this or sort of think about this is that, you know, the left side of the brain, the left hemisphere and the right hemisphere have different functions. I just want to make it clear to the listeners. I know you know this, right? But so they have different functions. So intriguingly, it's only in the right side.
