Each of the runners would represent a neuron and the baton would represent the chemical “information” carried along the neurons.

It would also be important to call attention to the point that there is a starting line and a finish line when it comes to neural activity. The electric signal has to start at a specific point, whether that is sensory neurons in the eyes or nose, and end at a specific point, maybe the cerebral cortex in the brain.
