What is the relationship between neurotransmitters and addiction?
The relationship between neurotransmitters and addiction is based on the ability of the addictive substance to interrupt the brain activity of the neurotransmitter. Neurotransmitters are messages sent between neuron and receptor. Pain, pleasure, boredom and other news travel through a neurotransmitter. Drugs, alcohol and other addictive substances not only prevent appropriate neurotransmitter activity, but also create brain activity that changes behavior.
Dopamine is a primary neurotransmitter influenced by addiction. This neurotransmitter affects movement control, emotions, pleasure and pain. Different drugs can stimulate or inhibit brain receptors of dopamine. This disrupts the ability of the neurotransmitter to work effectively.
cocaine is one of the examples of a drug that affects the effect of dopamine in the brain. The use of cocaine increases dopamine levels and creates temporary euphoria. Each medicine used either blocks or stimulates neurotransmitters, which affects the user of the). Some drugs, including amphetamines, disrupt normalThe flow of neurotransmitters of the brain. Other drugs bypass the neurotransmitter system completely and go directly to the receptors.
When neurotransmitters of dopamine are permanently excessive drug use, the brain stops creating dopamine itself. This is called desensitization, often referred to as drug tolerance. After removal of drug use takes weeks to months.
different drugs have different connections between neurotransmitters and addictions. For example, amphetamines increase dopamine release and cocaine binds to a neurotransmitter, reducing dopamine release, but both drugs create feelings of happiness and energy. The level and speed of changes in brain chemicals with drug use also affects neurotransmitters and addiction.
Father of certain drugs for neurotransmitters and addiction, some drugs are considered addictive than others. Crack cocaine and opiates including heroin, morphine and medication against prescriptionThey are considered very addictive. Marijuana is considered much less addictive. Nicotine is considered the most addictive psychoactive drugs.
chronic drug use, as can be seen depending on the impact of the function of the brain. Neurotransmitters and addiction are studied in an effort to understand their relationship and find a medicine. Research has found that chronic drug use changes the front bark of the brain. This is the area responsible for understanding the consequences of actions. Do not learn from mistakes, do not worry about risk and we do not care about the consequences, all the by -products of the relationship between neurotransmitters and addiction.
