When something is small enough, quantum effects are guaranteed to
be there.  Eccles points out that neurotransmitter vesicles and
synaptic gaps are indeed small enough.

>I suppose rolling dice is a quantum phenomenon!

It depends on the size of the die.  If you spin a benzene ring, you
better believe it's a quantum phenomenon.

>Perhaps I have missed Eccles point?

Is it clearer now?
