You recently read about Justin Bieber's unfortunate run-ins with glass doors and walls.  Since then, you learned about how neurons are the unique cell of the nervous system and that signals are sent via action potential along those cells.  You have further learned about how signals "jump" from one neuron to the next, allowing for your nervous system to function every single day. Explain, using language from your learning of signal transduction and the nervous system, just what Justin Bieber's neurons should have been doing to prevent his unfortunate accidents.  In other words, describe how are signals received, sent, and passed along in the nervous system (a system primarily responsible for preventing people from walking into doors and walls).  You may enhance your answer by comparing the effects of drug use with the inability to avoid these accidents. *Hint: half of your response should be about neuron anatomy and action potential and the other half should be about signaling across synapses.*
