| Moving in a little closer to the synapse, we can see some serotonin molecules floating around. We also see some serotonin reuptake transporters on the membrane of the axon terminal, as well as receptors on the dendrite of the nearby neuron. In order to understand how MDMA works in the brain, and why it produces the effects it does, you need to know what these reuptake transporters and receptors do. But first, just for the fun of it, let's look at an actual photograph of a synapse... |
