Question

Quizplus · Accepted Answer

Excitatory neurotransmitters work by depolarizing the postsynaptic membrane, making the neuron more likely to fire an action potential. This is typically achieved by opening sodium channels, allowing positively charged sodium ions to enter the neuron and reduce the membrane potential difference.
