Molly,a Second-Year Neuroscience Graduate Student,treats Neurons Grown in a Petri

Molly,a second-year neuroscience graduate student,treats neurons grown in a petri dish with drugs that "block" the function of neuronal receptors.What is a consequence of the drug treatment?

A) The neurons will become depolarized,initiating a refractory period.
B) The neurons will become hyperpolarized and less likely to initiate another action potential.
C) The synaptic vesicles will be void of neurotransmitters,blocking neuronal communication.
D) Action potentials will fire immediately,enhancing neuronal communication.
