Where one neuron ends and another starts, things can get pretty interesting. Your students can investigate the action potential of a neuron plus the interaction of neurotransmitters, membrane receptors, and transport proteins. Once students create their model to show the typical process for the neuron function, they can analyze where the process can break down. They then revise their model using representations of nicotine, cocaine, sarin gas, and propofol on neuronal signaling to predict the molecular and organismal response.
