Hi, Jim,

There is plenty of evidence that thinking starts, proceeds, and
finishes in the brain. With positron emission tomography it is possible
to observe the correlation of brain metabolism with various thinking
processes.

There are still many people who find this incredible. However the
argument from personal incredulity is not terribly strong, and AFAICS
there is no evidence for thinking occurring anywhere else.
Merry Christmas,

Zigoteau.
