WebAug 1, 2024 · When this message is passed between the two cells at the synapse, it has the power to change the behavior of both cells. Chemicals from the pre-synaptic neuron may excite the post-synaptic cell, telling it to release its own neurochemicals. It may tell the post-synaptic cell to slow down signaling or stop it all together. WebAxoaxonic synapses are between axons of two neurons. Axosomatic synapses have junctions, at an axon terminal of a neuron, and the cell body of another neuron. In an axodendritic synapse, synaptic contact is between an axon terminal of one neuron and a dendrite of another.
