As previously discussed, dopamine works with the brain's reward system to motivate people to act in ways that will bring them a dopamine boost. Of course, one way to get a strong hit of dopamine is drug use. Drugs like alcohol and cocaine, as well as less intense substances that some people use daily, such as caffeine and nicotine, all impact dopamine release. These substances increase the amount of dopamine in the brain, so the person feels compelled to keep using to feel the same reward for the behavior.
Substance tolerance occurs when the brain gets used to this increased level of dopamine, so the person has to use more and more of the substance to feel the same boost in dopamine as they did when they started using. Dopamine medications fall into one of two categories: agonists or antagonists. Dopamine agonists activate dopamine receptors to increase the amount of dopamine in the brain. They are useful to treat conditions related to dopamine deficiency, specifically Parkinson's disease.
They are also used to treat restless leg syndrome RLS , as the mechanism behind this condition is similar to what causes tremors in people with Parkinson's. Indirect agonists can be used to treat attention deficit disorders. By contrast, dopamine antagonists block dopamine receptors, similar to the functioning of an SSRI. These drugs are often used as antipsychotics, to treat conditions such as schizophrenia or bipolar disorder.
Serotonin and dopamine are just two of the many moving parts that make up the brain. Understanding these two neurotransmitters, and how they impact your mood and behaviors on a daily basis, can help bring you one step closer to comprehending the complex system that is the human body.
While the previous sections discuss how serotonin and dopamine levels can be adjusted through medication, therapy is a viable solution as well. In many cases, therapy is used alongside medicine to provide optimal results.
BetterHelp offers online counseling and therapy to anyone who may be struggling with depression, anxiety, or any type of mental disorder. Medications can be incredibly helpful to many individuals in need of treatment for depression, anxiety, and other conditions. However, medications can vary widely in their availability, side effects, and coverage by health insurance policies.
Seeking out alternative, non-pharmacological treatment options can also be highly beneficial. For instance, some researchers have recently investigated the benefits of laughter therapy in treating depression and naturally regulating serotonin levels. If you are dealing with depression or anxiety, your options for treatment are not limited to medications alone.
Online therapy may be particularly helpful in treating anxiety and depression because of its flexibility and private environment. If you pursue online therapy with a mental health professional through BetterHelp, you can arrange your own schedule of treatment with a matched therapist and choose to meet via video chats, phone calls, or messaging.
This ease of scheduling also means that your therapy can be kept as confidential as you like—no leaving work for an appointment or sitting in a waiting room. Typical barriers that may turn individuals away from seeking help for depression or anxiety can be avoided by using online therapy.

Long-term or chronic stress can also lead to elevated cortisol levels — a hormone released as a stress response. High levels of cortisol reduce the production of both serotonin and dopamine and have been linked to depression, says Nicole Avena , PhD, an assistant professor of neuroscience at Mount Sinai Medical School and a visiting professor of health psychology at Princeton University.
Dopamine and serotonin are both neurotransmitters that are involved in many similar bodily functions, though they have key differences in how they affect behavior.
Overall, dopamine and serotonin work together to help regulate mood, and low or elevated levels of either hormone may negatively impact your mental health. World globe An icon of the world globe, indicating different international options.

During neurotransmission, serotonin is released into the synaptic cleft , a gap between the presynaptic neuron and the postsynaptic neuron. Once here, the serotonin will either reach serotonin receptor on the postsynaptic neuron and continue down the next neuron via electrical impulses, or serotonin will be broken down by an enzyme called monoamine oxidase, or the serotonin will be reabsorbed back into the presynaptic neuron by a serotonin transporter.
Dopamine is also a neurotransmitter found in the CNS , which, alike to serotonin, is a monoamine neurotransmitter, meaning it is derived from amino acids. Dopamine is both an excitatory and inhibitory neurotransmitter and therefore has a variety of effects. Dopamine is primarily associated with feelings of pleasure, such as the satisfaction someone may feel from achieving a goal. It is also involved in feelings of motivation, sleep, attention, and memory, as well as being important in movement.
There is a reward system involved in dopamine which helps to incite positive mood and heighten motivation. During neurotransmission, dopamine is released from the presynaptic neuron in order to reach the dopamine receptors on the postsynaptic neuron.
Dopamine is highly concentrated in areas of the brain called the substantia nigra and the ventral tegmental area VTA in the midbrain.
Other brain areas dopamine can be made is in the hypothalamus and the olfactory bulb. There are dopamine pathways which can be triggered when exposed to a stimulus which is rewarding, resulting in increased amounts of dopamine to circulate around brain areas.
Once produced in the VTA, dopamine can be transported through these pathways, two of the main ones being the mesolimbic and the mesocorticol pathways. Once at the nucleus accumbens, dopamine levels here rise and then can be projected to the limbic system, specifically the amygdala and the hippocampus.
Connections to the amygdala can contribute towards feelings associated with the reward. Connections to the hippocampus can help to attribute memory and learning to the reward. Connections to both areas encourage the repetition of the rewarding experience or behavior. For instance, when eating a tasty food, pathways to the amygdala will associate positive feelings towards this food whilst the pathways to the hippocampus will help to remember the positive feelings towards the food, making it more likely that this food will be sought out again.
For the mesocorticol dopamine pathway, dopamine also gets activated in the VTA, but instead has direct connections to the cerebral cortex, primarily the frontal lobes. The frontal lobes are linked with high cognitive functions and so this area will encourage conscious experience of the pleasure and reward being experienced. This can attribute attention and motivation to the rewarding experience. Although serotonin and dopamine work differently and differ in function, neurotransmitters interact with each other in some way.
Serotonin and dopamine interact with each other to maintain a chemical balance in the body. Serotonin and dopamine have opposite effects on appetite. Whilst serotonin suppresses it, low levels of dopamine can stimulate hunger.
In anatomical studies, it has been found that dopaminergic neuronal bodies and terminals are modulated by serotonin, and they receive rich projections from serotonin neurons. These strong neuronal connections seem to promote the functional modulation of serotonin over dopaminergic activities in the neural network.
For instance, a serotonin receptor named 5HT2 seem to inhibit dopaminergic activity, whereas the 5HT2 receptor antagonists counteracts the inhibition of dopaminergic activity. Interactions between serotonin and dopamine could provide the framework for understanding the mechanisms behind some of the impulsive aggressive behaviors displays in people. Since serotonin is thought to have functional regulation over dopaminergic systems, deficiencies in serotonin functions may result in hyperactivity of the dopamine system, promoting impulsive behavior.
This relationship may account for some of the serotonin and dopamine dysfunctions in those with impulsive aggression. This is supported by studies on rats. It was found that after a fight, the rats had markedly decreased serotonin levels but significantly increased dopamine levels. All the same, be sure to take care of your body and brain by getting adequate rest each night and eat a nutrient-rich diet throughout the day, so that you'll have natural energy throughout the day.
Then, you won't need all of that caffeine! While there is not a hard reset button on these neurotransmitters, healthy lifestyle tweaks can naturally boost your dopamine levels. And many also help keep your serotonin levels stable. Follow these simple "do's" and "don'ts" to feel good, every day!
