Marcus works in the laboratory of Dr. Flores, an expert in the electrophysiology of squid axons. After taking a reading from a recording electrode placed within a squid axon, Marcus comments to Dr. Flores that the squid axon is at its resting potential. What measurement did Marcus take with the recording electrode?

How do hormones differ from neurotransmitters?

Joan, a neuroscience graduate student, is asked by her laboratory mentor to study the communication of two neurons grown in a petri dish. She is asked to stimulate an action potential in the first neuron, which will send a depolarizing stimulus to the second, "receiving" neuron. However, her mentor would also like her to block the receiving neuron from generating an action potential. How can Joan accomplish this?
