Final answer:
The two types of synapses in neuron communication are electrical and chemical synapses. Electrical synapses allow for direct ion passage between neurons, whereas chemical synapses work through neurotransmitter release and receptor binding.
Step-by-step explanation:
The two types of synapses involved in communication between neurons are electrical synapses and chemical synapses. In an electrical synapse, there is a direct connection allowing ions to pass directly between neurons, leading to virtually instantaneous signaling. In contrast, a chemical synapse involves the release of neurotransmitter molecules from synaptic vesicles into the synaptic cleft, which then bind to receptors on the postsynaptic neuron, triggering a response. This process introduces an approximately one millisecond delay due to the time required for neurotransmitter release and binding.
