    Neurotransmitters Essay

    • 4 Pages

    What are Neurotransmitters? The functions of the brain rely heavily on a complex system of communication. The brain’s process of communication is supported by a series of cells called Neurons which submit chemical charges known as Neurotransmitters. Neurons are the foundation for the brain’s functions and consist of three basic parts such as the Cell Body, Dendrites and Axons. The chemical transmissions from Neurotransmitters are the product of messages being communicated from one Neuron to the next through the axon of the cell. This message is better known as an Action Potential, which is “an excitation that travels along an axon at a constant strength”. (Kalat, 1992)Action Potential can be caused by sodium ions traveling through the axon…

    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…

    Specialized chemicals known as neurotransmitters carry signals across synapses. Each neurotransmitter is linked with particular effects depending on the distribution of each neurotransmitter among the brain's numerous functional areas. For example, dopamine is highly concentrated in regions that regulate motivation and feelings of reward (Dombeck, 2002). A neurotransmitter's impact also depends on whether it stimulates or decreases activity in its target neurons. Drugs make their effects by…

    Action Potential

    then the axon carries the action potential to its terminal buttons, and finally a neurotransmitter will be released. The neurons will send information, so it can travel down the axon and away from the body of the cell. The main goal of an action potential is to have a thought be created by the end of the process. A depolarizing current is created when an action potential explodes with electrical activity. It is important to remember that the transferring of ions across and through the axon walls…

    Amygdala Essay

    • 5 Pages

    The areas infected by psychiatric illnesses include the amygdala, the thalamus, and the hippocampus. The amygdala is located deep in the brain and is associated with one’s emotions. “The amygdala is activated when a person recalls emotionally charged memories” (“What Causes Depression” 2), memories in which spike an increase in neurotransmitters and never settles back down even after the memory is over. The amygdala activity is typically higher when a patient is depressed, and increased activity…

    Chapter twenty-eight discusses neurotransmitters and hormones. The neurotransmitter is a messenger that travels between a neuron and a neighboring neuron to transmit a nerve impulse. A hormone is also a messenger that is secreted by cells of the endocrine system and transported through the bloodstream to target cells, this is where it is stimulated. There are many similarities and differences between a neurotransmitter and hormones. Neurotransmitters are found in the nervous system. They carry…

    electrical signaling of the chosen neuron is to proportionally quantify the effects the chosen drug-caffeine has on the neurotransmitter Adenosine. Caffeine is a known antagonist of Adenosine, inquiring that it counters Adenosine’s inhibitory effects by a simple mechanism of competitive inhibition – not allowing Adenosine to bind…

    complex that disturbances in any part of it, including how neurotransmitters function, could affect your mood and behavior. Depression and Neurotransmitters Prior studies have shown that there is link between depression and pain, and due to the association between depression and pain, studies have focused on dopaminergic areas of the brain, which can be malfunctioning in depression (Taylor, 2015). The mesolimbic dopamine system, consisting of dopamine neurons in the ventral tegmental area (VTA)…

    The nucleus accumbens is the release sight for the neurotransmitter dopamine, a nature chemical in the central nervous system. When released in standard quantities, it assists in critical brain functions. Like most neurotransmitters, dopaminergic signaling entails an equilibrium between dopamine release and the re-uptake by presynaptic nerve terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the…
