Excellent point, and one that many fail to grasp. Indeed, I’ve always suspected your observation may be the best definition of ‘life’ we currently have; namely, living systems are composed of parts that are more complex than the whole. It’s a hard concept to articulate. But, as you obviously know, the principle is obvious.. it doesn’t stop with the neuron; I would suspect the neurons membrane or its organelles are more ‘complex’ than the neuron itself.
