Neuron Research Paper
A neuron is a nerve cell in the brain, it is essentially the building block of the nervous system. Each neuron is itself a miniature decision making device, reacting to signals it receives from hundreds, even thousands of other neurons. Each signal is either excitatory or inhibitory. Excitatory signals increase the likelihood of an action potential happening, inhibitory make an action potential in a nerve cell less likely. The action potential is a nerve impulse. Once the excitatory signals over power the inhibitory signals and action potential is triggered. So the neuron then fires, sending that impulse down its axon, transmitting information to another cell. The firing of a neuron isn’t based on intensity, its an all-or-nothing kind of response. A neuron either fires with a full strength response or it doesn’t fire at all. Once that action potential reaches the end of the axon, our body’s neural system converts that electrical impulse into a chemical impulse. Which is a neurotransmitter. A neurotransmitter is a neuron produced chemical that crossed the synapse to carry …show more content…
Glutamate is the major excitatory transmitter in the brain and is widely spread throughout it. Glutamate is involved in the most aspects of the brain, including big ones like your memory, learning, and cognition. Too much and too little of glutamate is harmful. Glutamate is both essential to us and highly toxic at the same time. Too much glutamate can lead to over excitation of the receiving nerve cell, but the receptor of glutamate on the receiving nerve cell can be oversensitive, so less glutamate molecules is necessary to excite that cell. Either way any cell activated by glutamate causes over excitement, and this over excitation can lead to cell damage and/or death. Drugs that can effect a person’s Glutamate levels are Ketamine, Phencyclidine, and alcohol. Which raise the levels, making it dangerous on the nerve

    The communication process of neurons in the brain occurs through an electrochemical process. Neurons pass neurotransmitters through the dendrites, which are attached to the ends of each neuron and receive messages from neighboring neurons. The chemical messages that are passed from one neuron to the next cause an action potential. This occurs when the receiving neuron accepts the right amount of the correct message. Once the message is received, the neuron will then send neurotransmitters to the next neuron through the axon. After the neurotransmitters pass through the axon they are released through the terminal buttons.…

    When an impulse arrives at an axon terminal, the vesicles release the neurotransmitters into the synaptic cleft. The neurotransmitter molecules diffuse across the synaptic cleft and attach themselves to receptors on the membrane of the neighboring cell. This stimulus causes positive sodium ions to rush across the cell membrane, stimulating the second cell. If the stimulation exceeds the cell’s threshold, a new impulse begins.…

    To better understand the fundamentals of neurochemistry, a good start is at the brain. The brain makes up the central nervous system and is connected to the whole nervous system that runs through the whole body. The central nervous system receives sensory information and controls the body’s response. For example, a pot on a stove would be extremely hot on the hands when the stove is on and would damage the skin. This sensory information is sent up to the brain to be processed. The brain then controls the body to remove the hand to prevent more damage. All this information travels through neurons. Neurons are nerve cells that are essentially the basic building blocks of the nervous system. They are required to communicate information in both chemical and electrical forms. To process information in the brain, neurons must work together in a circuit-like fashion to function properly. No one nerve cell or neuron can work alone. Neurochemistry studies how information is passed between the billion of neurons in the brain. Evaluating what happens when someone is addicted to a drug helps to further understand the neurochemistry in the body.…

    Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms synapses at their ends, which cover the cell body and dendrites.(Myers, 2013)Neurons send messages by passing impulses through their axons. The axons have different lengths. They range between a fraction of an inch and three feet or more. A layered myelin sheath, which covers the axon, enables information to be transmitted fast through the axon. The sheath consists of specialized cells in the brain, known as oligondrocytes and others in the peripheral nervous system called Schwann cells. Nerve impulses occur through the closing and opening of ion channels.…

    Neurons are the specialized cells which make up the body's nervous system. These nerve cells process and transmit information from one part of the body to another. For example, if you were to touch a candle flame for more than an instant, pain nerves also known as receptors that are in your finger would send a message up through your hand and arm to the spinal cord and then to the brain. The brain which in turn records pain and sends the messages back down to various parts of the body. You will the say “ouch” which is then followed by the body or hand jerking away from the flame as pain will be felt as this reaction is caused by the message which was sent through the brain. This all happens in milliseconds.…

    To explain the communication process of neurons in the brain we must first understand the how a neuron works. In view of the fact that neurons form a network of electrical activities, they somehow have to be interconnected. When a nerve indicator, or impulse, reaches the ends of its axon, it has traveled as an action potential, or a pulse of electricity. However, there is no cellular continuity between one neuron and the next; there is a breach called synapse. The membranes of the sending and receiving cells are separated from each other by the fluid-filled synaptic gap. The signal cannot leap across the gap electrically, so special chemicals called neurotransmitters provide this role.…

    Neurotransmitters are chemical messengers, which send signals and communicate information through neurons (nerve cells), cells, our brains and our bodies. Neurotransmitters are released and travel through terminals in the brain until they reach certain receptors. Neurotransmitters and their functions are located and carried out in different sections of the brain. It uses neurotransmitters to make your body carry out certain functions, such as making your heart beat and your lungs breathe. Scientists are not sure of how many neurotransmitters actually exist, but they can be sorted into two main different types. These are called exitatory neurotransmitters and inhibitory neurotransmitters.…
