Neurotransmission
As mentioned earlier (slide 3), information is communicated in the brain via a process called neurotransmission. Neurotransmission involves a variety of chemical substances called “neurotransmitters.” One such neurotransmitter is called “dopamine.” In the normal communication process, dopamine is released by a neuron into the synapse (the small gap between neurons). The dopamine then binds with specialized proteins called “dopamine receptors” (see slide) on the neighboring neuron thereby sending a signal to that neuron.
