The Effects Of Neurotransmitters On The Brain - 3080 Words

Experts believe bipolar disorder is caused by an underlying problem with specific brain circuits and the balance of brain chemicals called neurotransmitters (WebMD). There are five brain chemicals noradrenaline (norepinephrine), serotonin, dopamine, oxytocin, and endorphin. Noradrenaline and serotonin are the most common chemicals linked to psychiatric mood disorders such as depression and bipolar (WebMD). Dopamine is linked to the pleasure system in the brain (WebMD). When a disruption happens to the dopamine system connects to psychosis and schizophrenia (WebMD). If there is too much dopamine in one place, it can cause psychosis. Dopamine motivates us (Deans, 2011). Dopamine is linked to everything, metabolism, evolution, and the brain (Dean, 2011). Serotonin is connected to many different body functions including sleep, wakefulness, eating and impulsivity (WebMD). Researchers believe that abnormal brain functioning of brain circuits that involve serotonin as a chemical mes senger contributes to mood disorders (WebMD). Oxytocin is a hormone commonly associated with childbirth and breastfeeding. Oxytocin plays a critical role in social and emotional behavior. Oxytocin increases the susceptibility to feeling fearful and anxious during stressful events (NWU, 2013). The three most common psychotic disorders are schizophrenia, bipolar disorder, and dissociative identity disorder. They are also the most common disorders to be confused. Dissociative identityShow MoreRelatedNeurotransmitters And Its Effect On The Brain925 Words   |  4 PagesNeurotransmitters communicate by transmitting signals from a neuron to a target cell through a synapse. Before this communication can happen, the neurotransmitter must be synthesized and stored in vesicles so that when an action potential arrives, the cell is ready to fuss with the membrane of the neuron. When the synaptic vesicle is ready, the final triggering of vesicle fusion with the presynaptic terminal membran e occurs rapidly in response to the action potential invasion of the terminal.

Is everything we do, say, think and feel a direct output from nothing but the brain? Is it justifiable to think of the brain as interconnected box within box with inputs and outputs? The focus of this paper is on the input alcohol and how the processes generate a certain type of behavior output. This focus of alcohol input and behavior output will demonstrate that indeed brain is and does equal all forms of behavior.

Basically, these drugs hijack the neurotransmitters. Once these drugs are ingested, it enters into the brain, gets into the synapse and binds itself to the receptor. This then causes the inappropriate release of neurotransmitters and alter the breakdown and recycling of neurotransmitters or can be used to destroy particular neurotransmitters completely (Sapolsky, 2005, pRead MoreCompare and Contrast How Cocaine, Ecstasy, Heroin and Cannabis Work in the Brain1243 Words   |  5 Pagesthe Brain Drugs of abuse, such as cocaine, ecstasy, heroin and cannabis, are of natural or synthetic origin, which can alter the emotional state, perception, body functioning and behaviour of an individual. Drugs are known to work in the brain by activating certain brain circuits via different mechanisms, and stimulate or inhibit different neurons in the pathway. However, due to the effects of each drug being different, a drug will affect either different pathways and neurons in the brain toRead MoreEssay about Neurotransmitters1594 Words   |  7 Pages Neurotransmitters Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions acrossRead MoreLearning : Grow Your Brain Cells1202 Words   |  5 PagesLearning: Grow Your Brain Cells In the book Spark, written by Dr. John J. Ratey, he discusses how exercise can positively affect how your brain works. He provides studies and personal experiences to support the claims he makes. I always knew exercise would improve your life but never could have imagined how much it can affect your brain health as well. The chapter I thought spoke the most to me was chapter two, Learning: Grow Your Brain Cells. The chapter starts out by mentions Naperville, whichRead MoreNeurotransmitters and Behaviour Essay1482 Words   |  6 Pagesfunctions in life are controlled by neurotransmitters.’ Neurotransmission are the body’s regular chemical messengers which transfer data from one neuron to another. Thus, they are unquestionably one of the building blocks of behaviour. Neurotransmitters are potent chemicals that adjust various physical and responsive processes such as psychological performance, emotional conditions and agony reaction. Thence, relations between neurotransmitters and the brain chemicals have an unfathomable impactRead MoreEssay about Beh 225 Brain Response of Behavior1589 Words   |  7 PagesAppendix C Brain Response of Behavior Part I Note: Parts II and III follow below, complete all three.
