NEUROTRANSTITTOR AND PERCEPTION

1. Describe how neurons communicate with each other through electrical and chemical processes.
The human brain has two types of cells, neurons and glial cells. For a simplistic description, the glial cells are like the neuron maintenance cells, they are necessary to keep the neuron insulated and waste free, allowing the neuron to be more efficient in their job. “Glial cells also appear to influence the formation of synapses and to aid in determining which neuronal connections get stronger or weaker over time” Griggs, Richard A. (2014). Information is transmitted back and forth from the central nervous system (CNS) and brain by neurons, and glial cells. A neuron is made up of 3 basic parts: 1dendrites, 2the cell body and 3axon. According to Griggs, Richard A. (2014), neurons communicate in a specific pattern, first, the dendrites receive information from other neurons and that information is transmitted to the cell body. The cell body may or may not pass the information to other neurons, it makes the decision whether or not to send an electrical impulse. The electrical impulse travels down the axon,

Many of you know of Michael J. Fox’s condition with Parkinson’s Disease. What neurotransmitter is thought to be related to the development of Parkinson’s disease? What drugs are used to treat it and what are the drugs doing?
The drugs used in the treatment of Parkinson’s disease L-dopa, increasing the creation of dopamine once it’s in the brain, this drug treatment was discovered after injecting dopamine was an unsuccessful treatment because it couldn’t break the blood-brain barrier. By increasing the production of dopamine there are potential serious side-effects, and the treatment becomes ineffective for the patient as the disease as the disease progresses.
4. Heroin is obviously very appealing to some and it is also very addicting. What neurotransmitter is heroine affecting, what is it doing, and why is it so

    In neuronal development, the general rule is that cells are generated in sites different from those they later reside in. The Nervous System is the master controlling and communicating system of the body. Electrical impulses act as signaling device; they are rapid, specific and cause immediate responses. They also use sensory receptors to monitor changes called stimuli. This is where gathered information creates sensory input.…

    This is what helps people detect emotions of themselves and others. There is one amygdala on each side of the brain, they are a part of the limbic system, which is responsible for memory and survival mode. They help to store memories that we may not remember, and also to control aggression. http://study.com/academy/lesson/the-amygdala-definition-role-function.html The hypothalamus is a part of the brain responsible for producing hormones that the mind and body needs. http://www.healthline.com/human-body-maps/hypothalamus The hippocampus is what helps store long term memories, but never stores short term memories.…

    Elisabeth Helms Professor Michel PSY 435-01 28 August 2015 Assignment #2 What are the 3 major types of neurons? How are they functionally different? Why are the functional differences important? There are 3 major neurons that the nervous system uses to carry information throughout the body; sensory neurons, interneurons, and motor neurons. Each type of neuron, all functionally different, interacts with the central nervous system, the brain, and the muscles of the body.…

    Neurons have the metabolic machinery characteristics to somatic cells of other types. They have a nucleus and all other organs that are needed for a normal cellular life. Neurons are characterized by specialization in intracellular communication. Neurons in the matured CNS involves a secretion of special chemical molecules called neurotransmitters. Neuroglia provide a variety of functions for brain tissue and support the metabolic and signaling functions of the neurons.…

    The dendrites are branch like bushy extensions that receive the information and conduct impulses towards the cell body. The soma, or cell body, makes sense of the information and works It out. It also triggers the action potential and all or nothing response. The axon is a neuron’s extension that sends messages to other neurons or to muscles or glands. It transmits the Impulse, aka the action potential.…

    These determinants are influenced by the distance between the notochord and the neural tube cells.14 One of the key properties of Shh is that it functions in a dose dependent manner, it performs as a morphogen.14 It causes varying cell fates depending on its local concentration. Motor neurons are induced when the concentration is high. When the concentration is very elevated, floor plate cells are induced and when it is low central neurons are induced.14 When an early neural plate that has not yet been exposed to Shh is grown in vitro and exposed to different concentrations of SHH, different cell types are formed, showing the effect of Shh concentration on cell fate.14 Shh induces many types of ventral interneuron progenitors when it is produced ventrally in the floor plate, and notochord cells in spinal chord formation. Five different classes of neurons result from Shh selecting the identity of motor neuron progenitors. Differentiation is ended by the inhibition of Shh signaling.…

    The mammalian nervous system consists of highly specialised cells called neurons, alongside supporting cells. The human brain contains 1010 to 1012 neurons (1). Neurons have a distinct cell shape and range from microns up to a millimeter in length. Neurons’ unique structure allows for rapid and specific transmission of signals along a neuron, and from one neuron to another. Neurons transmit nerve impulses over long and thin axons, and receive information through branches of dendrites.…

    Topic: Understanding the Key Aspects of the Brain and the Nervous System. The entire human body activity relies on the brain function, in this first section of this report I will try to discuss the major structures, the functions as well as the major methods of studying the brain. The brain is in charge of all body functions, such as the ability to make decisions, do activities, learning and all everyday life stuff. The brain is situated in the skull protected by brain blood fluid. In the second section I will discuss the differences between Glial Cells and Neurones in relation to their structure and function, including the communication process amongst the Neurones and various types of Neurotransmitters as well as the conducts with which…

    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,…
