Definition of dopamine in English English dictionary: A neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system; A neurotransmitter released in the nervous system; A neurotransmitter that is essential for normal movement, such as walking The brains of Parkinson's disease patients are deficient in dopamine; a neurotransmitter involved in the inhibitory function of the basal ganglia; it is produced by the substantia nigra Lack of dopamine can result in Parkinson's disease; -a neurotransmitter made from tyrosine and L-dopa; The neurotransmitter that produces feelings of pleasure when released by the brain reward system; a hormone-like substance that is an important neurotransmitter In normal amounts it facilitates vital brain functions, but in imbalance it causes serious dysfunction Dopamine affects processes controlling movement, emotion, and the sense of pleasure and pain The chemical formula for dopamine is C8H11NO2; A chemical in the brain that is thought to be affected by ADHD; a neurotransmitter critical to fine motor co-ordination, immune function, motivation, insulin regulation, physical energy, thinking, short term memory, emotions such as sexual desire and autonomic nervous system balance; A neurotransmitter present in regions of the brain that regulate movement, emotion, motivation, and the feeling of pleasure; Dopamine is a neurotransmitter formed in the substantia nigra and transmitted, by the nigrostriatal fibres, to the striatum A decrease in the number of dopamine-producing cells in PD results in impaired communication between the substantia nigra and the striatum Dopamine deficiency is a causative factor of PD and is associated with bradykinesia, tremor, and rigidity Many of the drugs used in the treatment of PD alleviate symptoms by either replenishing dopamine e g levodopa or by mimicking the effects of dopamine; a chemical substance (neurotransmitter) manufactured in the brain that transmits messages between neurons (brain cells) involved in the control of movement Loss of dopamine due to degeneration of cells in the substantia nigra results in the symptoms of Parkinson's disease; A neurotransmitter of the catecholamine family, which also includes norepinephrine and epinephrine Dopamine is involved in emotional behavior, and at least 5 receptor subtypes have been identified Excess levels of dopamine are thought to cause schizophrenia, while low dopamine levels results in the shaking and lack of motor control seen in Parkinson's disease Neurogen is developing dopamine D4 receptor subtype specific antagonists Current evidence suggests that there may be more dopamine D4 receptors in the brains of schizophrenic patients than normal; A substance found in the brain that is involved in the sending of messages between nerves It is an excitatory, or stimulating neurotransmitter; -A drug that causes narrowing of the blood vessels Dopamine is used to treat patients who have abnormally low blood pressure (e g , those in shock) In low doses, dopamine is used to open vessels leading to the kidneys and thus increase urine output; Neurotransmitter in various brain structures important in motor action - loss of dopamine in certain structures results in Parkinson's disease; {i} neurotransmitter which works in conjunction to the brain to regulate movement and emotion (Biochemistry); A chemical messenger (neurotransmitter) in the brain that allows nerve cells to send communicate with each other; A neurotransmitter - a brain chemical that carries messages between brain cells Dopamine is associated with feelings of pleasure, usually after food or sex Drugs that artificially affect dopamine levels may cause craving for more of the drug; A chemical produced by the brain that assists in the successful conduction of electrochemical messages from one nerve cell to the next--governing actions of movement, balance, and walking; A neurotransmitter associated with movement, attention, learning, and the brains pleasure and reward system; A neurotransmitter of the central nervous system believed to play a role in schizophrenia It is synthesized from an amino acid by the action of certain body enzymes and, in turn, is converted into norepinephrine See also neurotransmitter, norepinephrine; a monoamine neurotransmitter found in the brain and essential for the normal functioning of the central nervous system; as a drug (trade names Dopastat and Intropin) it is used to treat shock and hypotension; an amino acid found in the adrenal gland Used to treat hypotension and Parkinson's disease; One of the catecholamines, widely distributed in the central nervous system. Through a series of enzymatic reactions (see enzyme) it is formed from levodopa and converted to norepinephrine and then epinephrine. It is a central nervous system neurotransmitter essential to control of motion; it also acts as a hormone. Degeneration of certain dopamine-producing brain cells results in parkinsonism; A neurotransmitter important in helping to regulate physical movement, pleasure, and thought and is missing in patients with Parkinson's Disease
