Which of these is the neurotransmitter associated with laughter?
Endorphins : "Humor involves the brain's reward system, which mainly uses dopamine as its neurotransmitter."
What does meth do to your body systems?
Meth affects the central nervous system by flooding the brain with dopamine, the neurotransmitter responsible for feelings of pleasure and reward. Because meth provides the brain with an artificial source of dopamine, it can cause the neurotransmitter to fire abnormally. The brain will then chase that rush of dopamine, quickly facilitating addiction to meth. It may then be difficult for the brain to produce dopamine normally without the presence of meth.
The satisfaction received in the process of performing an action is also known as?
Intrinsic Reward
What does HGH do to the body?
Ghrelin and Bulimia Nervosa (BN) Kalat (2007) discusses the phenomenon of increased release of the hormone ghrelin in those with BN. When compared with controls, those with BN had increased levels of ghrelin both pre- and postprandial (before and after meals)due to reduced ghrelin suppression (Jerlhag et al., 2006). According to the Journal of Clinical Investigation (2006) ghrelin assists in the balance of food intake, and energy output. Raised ghrelin increases food intake and weight gain (Kojima et al., 2005). Kalat (2007) reports that ghrelin has a role in stimulating stomach contractions upon food deprivation. Increased ghrelin is found in obese individuals with Prader Willi Syndrome, those with BN, and those with anorexia nervosa. Elevated levels of ghrelin may be associated with the oft reported feeling of loss of control during binge eating episodes (Kojima et al., 2005). It is postulated that increased levels of ghrelin boost production of dopamine, a neurotransmitter implicated in the reward system associated with addictive behavior (Jerlhag et al., 2006). Furthermore, Jerlhag et al. (2006) posited that the inhibition of nicotinic receptors by injecting nicotinic acetylcholine antagonists would decrease the effects of ghrelin. Similar to its involvement in other addictive behaviors, ghrelin may be involved in compulsive eating via neurotransmitter and hormonal pathways of the reward system (Jerlhag et al., 2006). Thus, it is proposed that psychopharmaceutical and clinical treatments might be developed to treat BN as an addiction and target symptoms when ghrelin is more clearly understood.
How does the brain react to drug and alcohol use?
How do drugs work in the brain?Drugs are chemicals. They work in the brain by tapping into the brain's communication system and interfering with the way nerve cells normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This similarity in structure "fools" receptors and allows the drugs to lock onto and activate the nerve cells. Although these drugs mimic brain chemicals, they don't activate nerve cells in the same way as a natural neurotransmitter, and they lead to abnormal messages being transmitted through the network.Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels. The difference in effect can be described as the difference between someone whispering into your ear and someone shouting into a microphone.How do drugs work in the brain to produce pleasure?Most drugs of abuse directly or indirectly target the brain's reward system by flooding the circuit with dopamine. Dopamine is a neurotransmitter present in regions of the brain that regulate movement, emotion, cognition, motivation, and feelings of pleasure. The overstimulation of this system, which rewards our natural behaviors, produces the euphoric effects sought by people who abuse drugs and teaches them to repeat the behavior.How does stimulation of the brain's pleasure circuit teach us to keep taking drugs?Our brains are wired to ensure that we will repeat life-sustaining activities by associating those activities with pleasure or reward. Whenever this reward circuit is activated, the brain notes that something important is happening that needs to be remembered, and teaches us to do it again and again, without thinking about it. Because drugs of abuse stimulate the same circuit, we learn to abuse drugs in the same way.

Is Chantix varenicline an anti depressant?
AnswerVarenicline (Chantix) is not an anti-depressant, but it does have some indirect actions on dopamine, which is a neurotransmitter that some anti-depressant medications work on. Here is how varenicline works in smoking cessation: nicotine activates the dopamine reward pathway (by acting on nicotinic acetylcholine receptors in your body) which leads to the pleasurable sensations and dependence associated with smoking. However, this pathway is only transiently activated by nicotine, and as nicotine levels begin to wane, users begin to experience withdrawal symptoms. Varenicline's partial agonist actions at the nicotinic acetylcholine receptor is believed to reduce withdrawal symptoms and craving in addition to preventing the reward effects of nicotine.
Drugs act on the neurons in the reward pathway or the?
Drugs act on the neurons in the limbic system.

When dopamine levels are elevated this reward pathway reinforces the use of the drug True or false?
Mesolimbic pathway - true. It travels from the ventral tegmental area to the nucleus accumbens.
When dopamine levels are this reward pathway reinforces the use of the drug.?
Dopamine is neurotransmitter produced naturally by the brain's pleasure and reward center (limbic system). Dopamine is produced natural when u are eating ice cream, exercising or watching your favorite movie. What illegal drugs or antidepressants do is that they cause an abnormal production of dopamine in the brain which causes the natural dopamine producing site to eventually stop dopamine production. The drug user will now be subservient on the drug to him or her happy(addiction).
