Aha, just saw this again, after @DougTataryn's BioEmotive retreat, and my perspective has shifted a bit. There's definitely something real to the triune brain model. Details can be debated but the prefrontal cortex does different stuff than the hippocampus & amygdala! π§ https://t.co/RWDkn8as4s
Eg I think that at LEAST 50% of the time (maybe 90%) when people I know talk about working with their System 1 & System 2 (Kahneman's terms) they're actually talking about their R & L hemispheres respectively. Similarly with triune model of brain, etc.
When I say "there's something real to the triune brain model" what I'm saying is basically "a 3-part model of intellectual, emotional, physical brain is better than not having those distinctions". Not dissimilar to this remark about hemispheres: https://t.co/rnG0jPyZWW
Pitch for why McGilchrist's @divided_brain model matters: Lateralization is not just in humans but in mice & birds & fish, so there's gotta be SOMETHING going on there. If you try to understand the rest of the brain while ignoring hemispheres, you're going to be confused!
Now my perspective is that when people I know say "S1 & S2", half the time they're talking about their hemispheres, and half the time they're talking about their emotional brain. The actual specific dual-process S1/S2 model is almost never what is meant. https://t.co/UOMZIBKQab
I don't have a coherent integration of McGilchrist's hemisphere model with this other major structure of the brain but I'm working on it. https://t.co/F4jW2K7ZeD
@jondubin @QiaochuYuan @Conaw @HareeshWallis I am so stoked to be able to start getting really clear about this stuff. People use terms like "system 1 & system 2" and by "S2" they mean the verbal loop (~= leftHem neocortex?) & by "S1" they mean EVERYTHING ELSE. But there's a lot to differentiate in that "everything else"!
The various dichotomies such as feelings vs reason are muddled in many ways. https://t.co/b36PDteNQ8
Here's my best one-tweet sketch of the difference between the emotional brain and the right neocortex. https://t.co/4H6n7w7hZq
@reasonisfun @diviacaroline @Aella_Girl @rothosphere One key difference between what I'm calling "intuition" and "feeling" is: β’ intuitionπ§ (~right neocortex?) is context-sensitive & aware of complex factors β’ feelingπ§ (amygdala etc) is simple & atemporal ("I feel scared because you spoke loudly like my father did when drunk")
But to the left neocortex, it's all either verbal/coherent or not. https://t.co/Kn9BNuPs72
@jondubin @QiaochuYuan @Conaw @HareeshWallis It makes sense to me that the left neocortex would treat everything else as a big blob, because it first & foremost makes a categorical distinction between its coherent articulable worldview (which it trusts at a level before awareness) and, well, everything else.
These models I'm presenting are tremendously oversimplified. The map is not the territory. But a sketched map of the territory is better than no map, as long as it doesn't contain grave errors and you don't take it to be more accurate than it is. https://t.co/6Jha8lxOyg
The important thing when using a map that isn't *extremely* precise (read: almost all maps) is to keep most of your attention on the actual world, and just refer to the map periodically. https://t.co/Kq9WXgLGvS
And within this sketch of a model, I'll suggest that if you imagine two hikers hiking together, the left hemisphere is the one staring at the map the whole time and the right hemisphere is the one looking at the world. They need to communicate to navigate effectively. https://t.co/u1Jpxah5Ox
I've found McGilchrist's model so valuable because it finally helped my left hemisphere identify *what it is* and *what it does*. And therefore also what it isn't, and what it doesn't need to do! https://t.co/7Uk82ygM1M
@meditationstuff @Timber_22 @noididntreadit Quote from Dzogchen book Roaring Silence that I like: > "Intellect itself needs to taste the manner in which it functions as a method of obscuring the nature of Mind." It captures a piece of the value I got from learning McGilchrist's hemisphere model: showed LH what it is.
