Dopamine is a chemical messenger responsible for transmitting signals between neurons. It is very evident in the transmission of nerve black fill invention to those of the corpus striatum, to facilitate a smooth, purposeful muscle activity. Dopamine is the immediate metabolic precursor of norepinephrine (also called noradrenaline) and epinephrine (also called adrenaline), ie, it is the raw material that the two materials are made. Dopamine can be either excitatory or inhibitory effects on neurons, depending on the characteristics of protein that combines with.
dopamine is associated with the perception of pain and pleasure. Increased dopamine in the frontal lobes reduces pain and increases satisfaction. If you naturally have more dopamine because a good personality, good genes and diet, he or she tends to tolerate pain better. That is why even when different people have the same kind of arthritis or back pain, some unbearable pain while others have no pain at all. In the TV House foster parents of the girl were suspected of abusing her. Although her body showed many signs of physical abuse, she did not complain of pain doctor. One of the residents used a bucket of ice to test their tolerance to cold. Although resident started screaming because of the extreme pain caused by cold ice when he took the test, the little girl was very quiet. Later, her doctors found that she had a gene that made her pain threshold above average. She may have increased the amount of dopamine in the frontal lobes of her, which makes it more tolerant to pain.
Dopamine is very involved in feelings of reward, vigilance and systematic behavior. Dopamine is commonly associated with the “pleasure system” of the brain, providing feelings of enjoyment and reinforcement to motivate us to do or continue doing certain activities. Dopamine is released by naturally rewarding experiences such as food, sex, use of certain drugs and stimuli that become associated with them. In milder disease, too much dopamine in the limbic system (a network of brain structures) associated with emotion and memory problems, and not enough in the cerebral cortex can cause overly suspicious personalities tend to prove paranoia that may inhibit social interaction.
Alcohol may increase dopamine levels in the areas of the brain called the mesolimbic system together with reducing the activity of enzymes that breaks down dopamine. When alcoholics suddenly stop drinking alcohol, their dopamine levels sink, causing discomfort, unpleasant feeling and anhedonia, the inability to experience pleasure from normally pleasurable events, such as eating, exercise and social interaction.
The sudden fall of dopamine could contribute to high ethanol cravings experienced by addicts, explained by Weiss et al. in the Journal of Neuroscience in 1996. This ethanol-induced changes in dopamine levels provide positive reinforcement that contributes to continued abuse. People who have stronger versions of dopamine when they drink alcohol or coffee tend to be addicted to alcohol, especially people who are very smart and do not enjoy social networking. Others do not have enough enzyme to process alcohol, so they feel stomach pain, nausea, dizziness. This group of people will never be able to enjoy alcohol.
acupuncture at a specific location HT7 (the ulnar end of the transverse increase in the wrist, in the depression on the radial side of the tendon central flexor Carpi ulnaris), but not in the control points PC6 (2 inches above the transverse increase in the wrist, between the tendons the medial palm aris longus and flexor medial radi domestic) or tail, preventing both reduction of dopamine levels in a particular brain region called the nucleus accumbens of ethanol stopped, an increase of dopamine levels caused by ethanol challenge. Activation HT7 facilitates normal dopamine levels in the brain after chronic ethanol exposure. If people are trying to stop drinking, acupuncture 2 to 3 times a week can help the body stabilize their dopamine level so they do not get depressed or agitated.
Nicotine causes tolerance and addiction by acting on the central dopaminergic pathways (those that use dopamine as a neurotransmitter), thus leading to pleasure and reward sensations. It stimulates the central nervous system, increases alertness and reduces appetite. Many women are reluctant to quit smoking because they are afraid of gaining weight. A 50% reduction in nicotine consumption may trigger withdrawal addiction individuals including anxiety, anger, sleep disorders, hunger, cognitive dysfunction and cigarette craving. Certain Drugs that inhibit the reuptake of dopamine are used to stop smoking. However, the drug can be dangerous for people who have epilepsy, eating disorders, uncontrolled hypertension, recent alcohol abstinence, or are in the current treatment with monoamine-oxidase inhibitors (medicines increase noradrenaline and adrenaline levels).
If you have smoked for more than ten years, several enzyme activities changed. When you suddenly stop smoking, reduce dopamine levels will make you feel miserable. Ear and body acupuncture can help the body to correct brain chemicals, produce more feel-good hormones such as dopamine, serotonin and endorphins, and reduce stress hormones, such as adrenaline and cortisol. Acupuncture stimulates your body to correct the complex hormone instead of just inhibit or induce the metabolism of certain hormones. It is difficult to use just one material change to explain the reactions throughout the body.
One woman had smoked a pack of cigarettes a day for 30 years before she started acupuncture treatments. After her best friend died of lung cancer at the age of 50, she decided to finally stop. She had acupuncture twice a week for 6 weeks. Surprisingly, she did not have any withdrawal symptoms or even increases. Another woman had several ear needles for 3 months; She never went back to smoking. Her daughter said she was surprised because her mother had been a heavy smoker for more than 20 years. However, not all have good stories. Two main factors affecting success are the extent of a person’s decision to stop and busyness plan relevant to stop the process.
Morphine can cause dopamine release, which causes addiction. Acupuncture can suppress Morphine withdrawal. In 2005, Dr. Kim and his colleagues in South Korea reported the results of a study on how acupuncture can alter dopamine levels and affect the behavior of rats sensitive to morphine. They based their findings in the journal Neuroscience Letter . Acupuncture at specific acupuncture point HT7, but not the control points (TW8 and tail), significantly reduced both dopamine release in the nucleus accumbens and behavioral hyperactivity induced systemic morphine challenge. These results suggest that the effect of acupuncture on morphine addiction occurs through normal dopamine and reduce behavioral sensitization to morphine.
