Since physical changes to the brain (deterioration or trauma, or even just hormonal and chemical fluctuation) can significantly alter both personality and memory, it seems to me that it's effectively proven that personality is not separate to the physical brain, and thus its very unlikely that an individual personality (as we understand it) persists when the brain is dead / destroyed.

As I know you've posted lots about ECT Redway, I think it's worth asking the question; how can you believe that an individual exists outside of their physical brain and persists when that brain ceases to exist, and also believe in ECT (that physically affecting the brain can alter mood or even personality)? I find the two to be inherently incompatible.
