Question

Quizplus · Accepted Answer

Both presynaptic facilitation and inhibition are mediated by axoaxonic synapses. Axoaxonic synapses are formed between the axon terminal of one neuron and the axon of another neuron. When a presynaptic neuron stimulates the axoaxonic synapse, it can increase or decrease the release of neurotransmitters from the axon terminal, leading to either facilitation or inhibition of the postsynaptic neuron.
