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!

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.

The obvious importance of the hemisphere axis to our experience of thinking & acting means that people are going to try to talk about itβ€”so if they refuse to use hemisphere terms, they'll use others. This then confuses the meanings of those other terms! https://t.co/4jhsw8EPJA

Most of the corpus callosum (L & R hemisphere connection) is inhibitory connections. I keep going on about internal conflict & I suspect that L↔R interaction represents a lot of that conflict. https://t.co/9DgeXxEqAE

(That's, of course, assuming that those other terms weren't already confused; I don't think Kahneman was confused about S1/S2 but other models probably come with such issues because they were developed during the Period Of Hemisphere Models Being Unfashionable To Talk About.)

Also I've written a new thread with updated thoughts about the triune brain model and how it relates to the hemispheres. https://t.co/FpeDG37zSM

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! 🧠 https://t.co/RWDkn8as4s

oh and here's an actual introduction thread to the model: https://t.co/OeBkaTTa96

Intro thread to Iain McGilchrist's work, based on his mini-book Ways of Attending: How our divided brain constructs the world. "Attention is not just receptive, but actively creative of the world we inhabit. How we attend makes all the difference to the world we experience." https://t.co/eys00Sn2vl
