The amino acid glutamate is believed to be the most widely used excitatory neurotransmitter in the brain. When glutamate is released from a nerve terminal, what will likely induce a depolarization in the post-synaptic neuron?
A. voltage-gated calcium channels
B. ligand-gated channels that allow both sodium and potassium to flow through the channels
C. direct activation of voltage-gated sodium channels by glutamate
D. inhibition of chloride channels
E. activation of a Na/K/ATPase-mediated electrical current
