Neurotransmitters Transmission

Improved Essays
After viewing the video on Neurotransmitters, in explaining how neurotransmitter transmission occurs, I would first tell my client that our brain has what’s called a reward system. When we use drugs, eat, gamble, shop, etc. the chemicals in our brain gives us a reward system that makes us feel good. Through our nerve cells in our brain, messages are delivered through what’s called neurotransmitters. Our nerve cells, also known as neurons are not connected and the messages must be sent from one neuron to another through what is called a synapse. Molecules (carrying messages), leave the Pre-synapsis neuron, through the terminal bouton and travel through the synapse to receptacles in the post-synapsis neuron. This is how communication takes place. …show more content…
When a person uses heroin, the chemicals enter the brain very fast, and they bind to receptors on cells. Some of these bind to cells that involve our feelings, such as pleasure and pain. Some people feel a “rush” when they use substances. The brain chemicals are affected by drugs because the chemicals in the drugs are very much like the chemicals in our brain. These drugs are basically imposters and the neurons recognize them. The neurotransmitters are the “feel goods” in our brains. For example: Dopamine is found in the limbic system, this is considered the pleasure center in our brain. GABA is associated with our sleep and reducing anxiety. Benzodiazepines have a similar chemical makeup. Endorphins and Enkephalins are our brains natural opiates. So, when your brain stops producing these natural chemicals and rely on the ones we put into our bodies, we cross the line into addiction. Using drugs repeatedly can cause a pattern to be imprinted or hardwired in our brain. This is dependence, physically and psychologically. We become addicted to the feelings that our brain produces. And when the effect of the drug wears off, then there is regret, depression, and the feelings are worse than

    When an individual does drugs, I learned that our brain does not work correctly together. Our brain interprets the drugs that an individual ingests as pleasurable, so dopamine is released. This makes the human brain assume that drugs are needed for survival. Drugs change the chemistry of the brain and change what our brains perceives as our basic hierarchy of needs. After one becomes addicted to drugs their primary survival priority is drugs, followed by what non- addicted brains consider priorities, food, sex and…

    The synapses have receptors on them and the response of the drug depends on which receptor it binds to. Each receptor has its own response to a very specific drug. These responses can sometime benefit or harm the person depending on what drug binds to which receptor. 7.

    The brain is an organ made up of cells known as neurons which communicate using chemical signals that involve neurotransmitters such as serotonin, norepinephrine, and dopamine. The turnover model, which is composed of five steps, explains the process neurotransmitters undergo in order for them to be released and have an effect. It is important to note that drugs specifically target one or more of these steps in order to be effective. The first step is biosynthesis, which is when the presynaptic cell synthesizes neurotransmitters when a precursor interacts with an enzyme. For example, when the precursor tyrosine interacts with the enzyme tyrosine hydroxylase, it becomes L-Dopa, and when that precursor interacts with the enzyme DOPA decarboxylase, the outcome is dopamine.…

    The brain is being awarded by Norepinephrine and Dopamine while it’s paying attention. Although these benefits often sound appealing the side effects do not; many side effects include “nausea, loss of appetite, dry mouth, anxiety, agitation, mood changes, sleep problems, headache ,dizziness… fast, pounding, or uneven heartbeats, numbness, tingling, and dangerously high blood pressure” (Joern et al. par. 9). The second hormone released by taking neuroenhancers is Dopamine described by Joern and other authors as a hormone “responsible for pleasures related to motivation, emotional states, and internal reward systems” (par. 6). Christopher Bergland’s “The Neuroscience of Perseverance” explains the scientific reasons why the brain enjoys Dopamine.…

    Dopamine is the main reward pathway as well as being a hormone it’s the main factor that impacts an individuals feeling of pleasure. However, when taking a drug this can work in place of the chemical neurotransmitter, therefore interfering with the balance of this chemical to make it imbalanced and therefore disrupting behavior of the typical neural communication. An example of this is the use of conventional antipsychotic drugs in the treatment of schizophrenia, these bind to dopamine receptors but don’t actually stimulate them and consequently because of this these are known as antagonists, this therefore has the effect that it reduces stimulation of dopamine particularly in D2 receptors; doing this reduces the amount of dopamine transmitted to the postsynaptic neuron decreasing and by doing this it therefore stops the brain receiving this excess of dopamine delaying the effects which is thought to cause schizophrenia when there is an excess eliminating the symptoms (Wiley & Sons,…

    My favorite neurotransmitter is serotonin because it involves sleep, mood, anxiety, and appetite. Serotonin is found in the lower part of the brain it can either be excitatory or inhibitory, meaning it can produce excitement or to prohibit you from doing anything. Tryptophan is an amino acid that is found in cheese and nuts and once consumed it is turned into serotonin. Therefore, if one wants to know how to boost your serotonin levels up, one can go outside and be exposed to the sunlight or also meditate and exercise. Serotonin impacts every part of the body that’s why it’s important to have serotonin in the body.…

    Medicated Assisted Treatment: A Starting Phase to Recovery Between 26 and 36 million people abuse opioids in the world (Volkow 2014) and every nineteen minutes someone in the United States dies from an opioid overdose (CDC 2012). A person often continues their use of opioids despite negative consequences due to the fear of withdrawal and lack of coping skills. Medication assisted treatment (MAT) for opioid addiction is an option which stops withdrawal symptoms, provides stability and accountability for the individual and can help guide a person to a healthy, stable and productive life. Despite the success and demand for MAT, it “remains grossly underutilized in many addiction treatment settings, where stigma and negative attitudes…

    This may lead to exaggerated messages and cause problems with communication within the brain. Drugs of abuse such as nicotine, cocaine, marijuana, and others affect the brain’s “reward” circuit. This particular circuit is located in the limbic system of the brain. Normally, when dopamine is released, the “reward” circuit creates feelings of pleasure. When drugs take control of this system, large amounts of dopamine are released; this causes the “high” or euphoria linked with drug use.…

    There are three criteria used to determine whether a chemical serves as a neurotransmitter: (1) is the molecule synthesized by and localized in the presynaptic neuron? (2) Is the molecule released upon stimulation? (3) When experimentally repeated, does the molecule mimic the effects in vitro versus when the presynaptic neuron releases it naturally? In regards to illustrating that ACh fulfills the criteria, the first criteria would have to be satisfied by either performing in situ hybridization or immunocytochemistry. A person would then have to satisfy criteria 2 by taking a sample of the fluid surrounding the presynaptic neuron and then test it for the molecule of interest.…

    . Neuromodulators are messengers released by neurons that can control the activity of neurons without specifically causing a depolarization or hyperpolarization. They are found in the central nervous system, and they affect certain groups of neurons or effector cells that have the appropriate receptors. However, neuromodulators can be used to treat epilepsy, other pain syndromes and even certain movement disorders. Examples of neuromodulators are as follows; a. Noradrenaline (Noradrenaline system).…
