WebFeb 13, 2016 · During synaptic transmission, the neurotransmitters interact woth ion chambers, slotting into the receptor sites. This changes the channel's shape and allows ions to travel through. Once they have opened the channel (sort of like a key), they diffuse back across the synapse to the sending neuron.
