    What is a Neuron?

    • 881 Words
    • 2 Pages

    What is a Neuron? Human brain consists of billions of cells interconnected together, with each performing its separate functions. It consists of two explicit categories of nerves: neurons and glia cells. Neuron is a single nerve cell in the entire nervous system; which is electrically excitable cell that carries information after being processed via chemical or electrical signals. One of its key characteristics is that it does not undergo cell division. In addition, it maintains a voltage gradient

    is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information. Neurons are not necessarily intrinsically great electrical conductors, however, they have evolved specialized

    hypothesized that the activation of the noradrengic neurons in response to stimuli leads to the strengthening of specific synapses in the cortex which results in the appropriate response. However, the changes that these neurons themselves undergo due to experience or the changes in the neural circuitry between these neurons and neurons of the cortex are unclear. The present study was aimed at understanding how the activity of locus coeruleus neurons leads to cortical plasticity through norepinephrine

    Mirror neurons have been one of the most exciting neurological discoveries in recent years. Some researchers have even gone as far as comparing the discovery of mirror neurons to DNA. Mirror neurons may be analogous to other human sensory systems and some believe that mirror neurons represent their own unique sensory system. Mirror neurons fire when a person or animal performs certain activities as well as when they watch another perform the same activity (Winerman, 2005). Basically, they allow animals

    The MECP2 protein is primarily necessary for the growth of neurons. However, the loss-of-function mutation to the MECP2 gene causes a decrease in neuron size and dendritic arborization (3). Individuals with the dysfunctional protein typically start out with normal development until about 18 months of life, and then undergo a short period of time where development ceases to occur, followed by rapid deterioration in language and motor skills. Individuals cannot clinically be diagnosed until after

    of the body to another, but in a different way than in an ordinary conductor. The electrical properties are different in neural conduction because it is slower and does not very in strength (it is a all-or-nothing conduction). A nerve cell (neuron) is the basic building block of the nervous system and is specialized to transmit information. It consists of a cell body and two types of branchlike fibers, dendrites and axons (top of Figure 1). Dendrites, along the cell body, receive information

    has a superior visual system to the female which he can use to locate and intercept the female fly in flight; however, the female fly does not have this advantage. The male-specific neurons that control the fly's superior visual system are complicated and intricate. The history behind the study of the fly's neurons begins with a 19th Century scientist by the name of Cajal. He studied neural systems and was the first to isolate nerve cells near the surface of the brain. His work led to a greater

At the commencement of the 20th century, Sherrington was the first person to describe the minute gap between neurons connecting different cells it was termed the ‘synapse’. Over numerous years of studying Sherrington concluded his findings to a theory he stated that “the nervous system acts as a coordinator of various parts of the body and that reflexes are the

    possible without an intricate network of neurons. Neurons are the nerve cells that transfer information within the body. They are the fundamental units of the nervous system and they have a specialized structure that allows them to use pulses of electrical current to receive, transmit, and regulate the flow of information within the body. By communicating through long-distance electrical signals or short-distance chemical signals, just a few connected neurons can perform highly complex tasks such
