Activation of Nicotinic Receptors Can Increase Release of Neurotransmitter Without

Activation of nicotinic receptors can increase release of neurotransmitter without affecting the firing rate of a neuron

A) by allowing neurotransmitter to pass through the channel of the receptor.
B) if the nicotinic receptors are located right on the presynaptic terminal of the neuron.
