Neurotransmission. &nbsp The brain is made up of millions of cells. The cells in the brain that are affected by MDMA are called neurons. Neurons are very important because they allow certain regions of the brain to interact with one another. A very helpful model when imagining the neurons in the brain is the Internet.hen this electrical impulse, called an action potential, is produced in the postsynaptic neuron, it will travel through the neuron (its axon, cell body, and dendrite) and begin the whole process of neurotransmission again.
