Dear Veronica,
Indeed, simple pop science models of the relationships between the left and
right hemispheres of the brain have been rightly debunk many years ago.
My posting references the recent work of Iain McGilchrist.
I think you will find his vastly more complex model interesting, at least.
For example, he is able to account for why a person with a right brain
stroke, leading to paralysis of their left arm, can offer no account of
injury to their arm. They will deny there is any problem with their arm.
When it is shown to them that their left arm doesn't work, they simply say
it's someone else's arm.
However, if you tell them that you have just injected their left arm and
paralysed the arm, they will then tell you their left arm doesn't work
because you paralyzed it.
With a left brain stroke, leading to paralysis of the right arm, the
patient clearly understands that their right arm is paralysed because they
suffered a stroke to the left side of their brain.
One of the surprising facts is, that in the reciprocation and exchanges
that take place, the left hemisphere inhibits information from the right
hemisphere on a massive scale. The right hemisphere accepts almost all
information from the left. Why?
cheers
