How Dopamine Works Human Body

Experts believe bipolar disorder is caused by an underlying problem with specific brain circuits and the balance of brain chemicals called neurotransmitters (WebMD). There are five brain chemicals noradrenaline (norepinephrine), serotonin, dopamine, oxytocin, and endorphin. Noradrenaline and serotonin are the most common chemicals linked to psychiatric mood disorders such as depression and bipolar (WebMD). Dopamine is linked to the pleasure system in the brain (WebMD). When a disruption happens to the dopamine system connects to psychosis and schizophrenia (WebMD). If there is too much dopamine in one place, it can cause psychosis. Dopamine motivates us (Deans, 2011). Dopamine is linked to everything, metabolism, evolution, and the brain (Dean, 2011). Serotonin is connected to many different body functions including sleep, wakefulness, eating and impulsivity (WebMD). Researchers believe that abnormal brain functioning of brain circuits that involve serotonin as a chemical messenger contributes to mood disorders (WebMD). Oxytocin is a hormone commonly associated with childbirth and breastfeeding. Oxytocin plays a critical role in social and emotional behavior. Oxytocin increases the susceptibility to feeling fearful and anxious during stressful events (NWU, 2013).

The neurotransmitter dopamine is usually affected by addictive substances as well as implicated in disorders such as depression, schizophrenic psychosis, and bipolar. Because of the overlapping in substance abuse disorders and mental health illnesses, this suggests that brain changes in one will create changes in the other. Stress has also been identified as a risk factor for addiction and mental illnesses and is the biological link between these two disorders.

Of the six most common neurotransmitters, dopamine is probably the one people know the most about. Dopamine is involved in controlling the reward and pleasure system in the brain. It allows us to recognize rewards and helps give us the ability to go after them. Learning, behavior, and cognition are also affected by dopamine levels. As with anything, if you have an imbalance, then bad things can happen. Parkinson’s disease can be caused by low dopamine amounts. People who have low dopamine levels can be addicted to substances easier.

Dopamine: This chemical controls body movements. Lack of dopamine means you will no longer be able to control your movements very well. Dopamine also controls the transportation of information

Love is an interesting mock trial of chemicals in the brain. Love’s mock trial of dopamine, phenylethylamine and oxytocin are all chemicals that are produced heavily in the first stages of when someone falls in love giving a person a sort of uplifted and euphoric feeling. The interesting piece to it is the chemical reactions start to lessen after time and the ‘high” is gone. This is one reason why scientists claim breakups, divorces, and other forms of separation is so very common. Now what if an imbalance in the chemical reaction countered or changed the brain in a way that the love never could faded? A possible imbalance between neurotransmitters serotonin and dopamine cause a disorder known

Dopamine is produced in the substantia nigra, as well as in the adrenal glands and is transmitted to the basal ganglia along a connecting neural

The major support and refutation of the dopamine hypothesis has come from the examination of dopamine receptors in these regions of the brain. There are two main types of dopamine receptors, D1 and D2. However, within the category of D2 receptors, there are three subtypes, D2, D3, and D4. (5) Through PET scan analysis of dopamine usage in the brain and post-mordum molecular analysis of brain tissue, researcher were able to determine relative levels of dopamine receptors in patients with schizophrenia compared to non-schizophrenics. Overall analysis of dopamine

Information from the nigra cells passes through the synapses with the aid of a specific hormone, dopamine, which is a significant chemical transmitter in the brain. Because the existence of dopamine is essential to the function of the substania nigra, it is also essential for the various muscular activities controlled by the striatum, such as walking, balance, etc. (16).

    In the human brain, the neurotransmitter that helps regulate voluntary body movement and emotional responses is known as dopamine. It also helps control the reward and pleasure centers of the brain.

Over the years, experiments have produced evidence to suggest that dopamine plays a role in the development of Schizophrenia (Howes, McCutcheon, & Stone, 2015). Dopamine is a neurotransmitter that is produced in the substantia nigra and ventral tegmental regions of the brain. The belief that dopamine was involved in Schizophrenia arose after multiple studies performed with compounds produced an increase in extracellular concentrations of dopamine (Lieberman, Kane, & Alvir, 1987). The patients that were administered these compounds had similar symptoms to those observed from patients who were diagnosed with Schizophrenia (Lieberman et al., 1987).

Dopamine is a neurotransmitter that belongs to a subcategory of monoamines called catecholamines. C8H11NO2 is the chemical formula for dopamine. It is found naturally in the human body as immediate precursor of norepinephrine. It is associated with controlling the brain's reward and pleasure centers. Dopamine effects mood, learning and providing feelings of enjoyment and power that motivates us to take action and do, or continue doing an activity. [source 9]

It was reported that the dopamine oxidation to dopamine quinone on CNTs is reversible in cyclic voltammetry [136]. The heterogeneous electron transfer between the electrode and the catecholamine is strongly affected by adsorption of the catecholamine on the electrode surface [137].

There are two types of people that have equally high levels of dopamine, but there may be different symptoms. It is said that it may be due to changes in dopaminergic receptors and how the brain processes the dopamine. Half of the people that usually have high dopamine are people who experience agitation, anxiety, cognitive acuity, feelings of pleasure, hedonism, high energy, high libido, hyperactivity, insomnia, learning, mania, motivation, organization of thoughts, paranoia, productivity, reward seeking, self-control, social seeking, and people who experience a lot of stress, according to the article High Dopamine. The other half of the people with high levels of dopamine in certain areas of the brain have more physiological and psychological reactions. The levels of dopamine can be reduced by increasing serotonin production for people without mental illness. People with mental illness that have high dopamine levels can decrease the harmful effects by taking antipsychotics. Too much dopamine can be extremely dangerous and causes dysfunctional symptoms (High

In the brain, dopamine operates as a neurotransmitter: a chemical released by neurons to send signals to other nerve cells. The brain contains several different dopamine pathways. Dopamine plays a role in regulating information from different areas of the brain. Dopamine mediates pleasure within the brain. It is released during pleasurable situations, so that one experiences delight in activities. Levels of dopamine in the brain help revamp memory. It also helps in concentration and reflex. In addition, it regulates control of motor functions, and is said to be crucial to learning.

The mesocoticolimbic dopamine system mediates positive reward and reinforcement. In individual’s electrical stimulation of some brain regions produced feelings of quasi- orgasmic sexual arousal, lightheadedness, and absence of negative thoughts. These brain regions mediate human hedonic or pleasurable experiences brain reward and reinforcement system is believed to be essential for survival of the individual and species. The system includes peptides and hormones, the DA system in the ventral tegmental area and striatum, and cortical areas that process affect, motor and cognitive information. Food affects first multiple peripheral and central mechanisms that directly and indirectly convey information to the brain’s DA reward pathway. In contrast,
