None of that points to anything remotely resembling evidence in support of the nature of thought being physical.
And I'd like to knowhow exaclty, from the above, you reached this fantastic conclusion!
- In all cases to date thought has been shown to be related to electrochemical activity detected in nerves (using an electroencephalogram and other measuring techniques).
No one disputes this
.
- Neural activity has been shown to be associated with neural infrastructure i.e. brain and nerves ... if nerves or brain are not present there is no evidence of neural activity. If neural activity is not detected it is generally accepted that the neural infrastructure has ceased to function and the person within which that infrastructure exists has died.
Ditto
.
- If a person damages his arm so severely that the nerves are cut that person will lose the use of that limbs unless those nerves can be rejoined.
Don't get why you wrote this. Like you think somehow thought can magically control severed arms?
.
- If a person is involved in an accident or has an illness (e.g. a stroke) that’s severely affects the neural infrastructure of the brain not only is mentality, personality and other aspects associated with mind/thought often affected by sometimes this can result in an extreme character change as happened to my uncle when he had a stroke.
Physical damage affects personality and cognitive processes, sure. The brain is a physical entity.. we know this. Thought is generated in the brain. We know this too. That damage effects cognitive processes.. well I wouldn't conclude anything other. I think this is an "ooh look - he stops thinking when we pull his brain out" revelation.
.
- Chips (computers) can be implanted in people brains to rectify serious mental conditions ... one woman was seriously depressed (so depressed that she was unable to even get out of bed and face the world most days) but a chip and electrodes placed in her brain which applied selected voltages across parts of it in multiple areas gave her what she referred to as "new light of day" for the first time in decades.
Stimulating areas of the brain with electrical impulses would no doubt screw up thought generation. Nothing about physical thought there tho'.
.
- Japanese scientists have programmed computers to display primitively translated thoughts on screens having first analysed the associated electrochemical impulses.
They're displaying electrical impulses. Not thoughts.
.
- The basic structure of the brain and which parts of it are associated with specific functions and with aspects of our intelligence and personality is understood to some degree.
Indeed.
.
- There are literally thousands of reputable mind/brain journals so it is naïve to believe we (the scientific community) don't understand a thing or two about mind/brain function and its relationship to thought.
The relationship is not the subject. Generation is not the subject. Your claim that thought has to exist on a scale of physical existent property is.
.
- Single cells have been shown to become highly activated during the watching of specific videos and the request to the subjects to think about the same stuff again (no video) shows the same patterns of activation.
You're looking at the engine rather than the passenger again.
