Based upon your authoriy, I presume. In any event, not according to Walker, a physicist of some accomplishment.
No, any decent book on solid state physics will do. If you do a search on the web using the string 'coherence lifetime temperature', you'll get a bunch of references. You'll probably need a course in q.m. and maybe thermodynamics to make sense of it, but I can't help that.
In any event, not according to Walker, a physicist of some accomplishment.
It's a pop physics book. It wasn't, as far as I can tell, reviewed much in the serious scientific press. But I did find one review by a real physicist.

Excerpt:
Walker attempts to tie together quantum theory and neuroscience by arguing that quantum tunnelling has a vital role in synaptic transmission. This depends upon very specific and technical assumptions about the mechanism involved, for which he refers to Walker (1977). In that paper, he claims that his theory 'predicts specific results for future experimental work. Its utility will be measured by the validity of these predictions.' It is disturbing, therefore, that his book gives no more recent references to work in this area, despite the fact that synaptic structure and function are among the most studied topics in neuroscience. A magnificent survey of the entire field which has just appeared (Cowan, S¨udhof, and Stevens 2001), certainly leaves no space for his hypotheses.
Quintessential fringe science, in other words. Some very fine minds have gone off on similar tangents. London thought DNA replication could be explained by superconductivity. Linus Pauling (perhaps the greatest chemist of the 20th century) spent years promoting ideas on Vitamin C that were nonsense.
