As a layperson, I've given a lot of thought in recent months to Dr. Hameroff's work and ideas. To a great extent I agree with his assessment that our consciousness is tied in some way directly in our brains to some Plank scale characteristic which is physically fundamental (universal) as described by Dr. Penrose. However, his ideas expressed here that our personal consciousness could survive death intact is a step too far for me. 

When a person dies and then has a near death experience, there is evidence that certain brain activities continue for a time even after death. It seems common sense to me that this activity could/would produce personal experiences, which can be recalled on revival from death. However, I don't believe this can be extrapolated as evidence that the 'soul' as Hameroff describes it, is separating from the physical construct of the brain. Rather, the brain in a near death context remains active and experiential for a time after death and this is being recalled.

Clearly, the physical construct of our brains enables conscious experience. However, once this construct is destroyed, I don't agree that a coherent continuation of a person's consciousness can continue, as it is dependent and arises from this physical construct interacting with Plank scale characteristics underlying our physical world. However, yes, the Plank scale characteristics in our physical world are entirely unaffected and continue.
