It's the one that a with which we do all our talking and and arguing.
But also it it's fascinating in looking at the way in which the two hemispheres mutually inhibit one another across the corpus callosum, the band of tissue at the base of the brain through which they're
connected and the function of the corpus callosum is
To convey information, but very largely to inhibit the other hemisphere from acting when one of them is active.
So there's a constant reciprocal interaction between them.
But the fascinating thing is that the left hemisphere is better able to inhibit the right than the right is to inhibit the left.
So it it's dominant in that way, even though in terms of the importance of what it can tell us, it's secondary.
The other thing is the left hemisphere's system, as I say, is self consistent in a simplified way.
So it can dilute itself.
it can dilute itself that it knows everything.
Whereas I see the the right hemisphere as seeing things that lie beyond
what we ourselves conceive.
So it's all the time as it were grasping
Or trying to grasp uh reaching out towards something that is beyond us.
Well there's a lovely lovely piece of um research by uh Daglin and Kinsbourne two quite prominent neuroscientists.
They
asked the same questions to individuals with both their hemispheres intact and working.
Was just the left hemisphere functioning and was just the right hemisphere functioning.
There are ways of temporally inactivating one hemisphere or the other, and what is extraordinary is that
When completely false propositions are put to the left hemisphere, it accepts them as valid because the internal structure of the argument is valid.
