" They basically suggest that specificity allows for a handful of neurons, whose activity is too faint to be measurable, to hypothetically explain lifetimes of complex and coherent experiences. Resuscitation specialist Dr. Sam Parnia’s candid rebuttal of this suggestion seems to frame it best: ‘When you die, there’s no blood flow going into your brain. If it goes below a certain level, you can’t have electric activity. It takes a lot of imagination to think there’s somehow a hidden area of your brain that comes into action when everything else isn’t working.’38 But even if we grant that there is hidden neural activity somewhere, the materialist position immediately raises the question of why we are born with such large brains if only a handful of neurons were sufficient to confabulate unfathomable dreams. After all, as a species, we pay a high price for our large brains in terms of metabolism and in terms of having to be born basically premature, since a more developed head cannot pass through a woman’s birth canal. Moreover, under ordinary conditions, it has been scientifically demonstrated that we generate measurable neocortical activity even when we dream of the mere clenching of a hand!39 It is, thus, incoherent to postulate that undetectable neural firings – the extreme of specificity – are sufficient to explain complex experiences.
