Why are neuron axons long and spindly? Study shows they’re optimizing signaling efficiency

A team of bioengineers has answered a question that has long puzzled neuroscientists, and may hold a key to better understanding the complexities of neurological disorders: Why are neuron axons designed the way they are? The answer — that they’re designed to balance the speed that information flows into the neuron relative to the time it takes the neuron to process that information — seems intuitive, but has never been quantified until now. https://www.sciencedaily.com/releases/2018/07/180711153609.htm
