In each of these ways and more, drugs can damage and vandalize the complicated circuit of nerve pathways in your body. Treatment for drug addiction stops this cycle. A network of so intricately designed to reason, imagine, compute, remember, and dream is truly incredible-not something to be tampered with. Central to treatment is the idea that the vast network of neurons in our bodies can be treated with care and respect. These neurotransmitters cross the gaps between neurons and trigger electrical and chemical changes.
Neurotransmitters attach, or bind, to certain receptors.
Binding creates chemical and electrical changes in the receiving neuron. Dopamine is a sample neurotransmitter useful in understanding addiction. Drugs can stimulate or block dopamine receptors. Drugs can also act directly or indirectly on those receptors. What's more, neurons can become sensitized or desensitized to dopamine.
