Neuron

The modern technology allows the researcher to know more about the cognitive processes. Neuron-imaging techniques allow the researchers to learn about the brain structure and functions. This will help them to understand the difference and the relationship between cognitive process and behavior. There are different types of brain imaging technologies: PET- Positron Emission Topography, MRI- Magnetic Resonance Imaging, frMri- functional Magnetic Resonance Imaging EEG: Electroencephalogram and CAT-…

The connection between mirror neurons and ASD provides an example of how an understanding of the mirror neuron system can be used to better understand empathy in individuals who are especially impacted. Contention in the Field A large portion of the scientific community is animated by the recent mirror neuron findings and continue to research these neurons extensively, however, some dispute the proposed implications of these neurons, or even their existence all together. Luca Turella, a…

neural operations in the nervous system, (Carlson, 2013). Carlson (2013, p.36) indicates the general functions of the glial cells as: keeping neurons in place; supplying neurons with nutrients and the chemicals needed to communicate with each other; protecting neurons from each other to promote coherent messages; and “destroying and removing the carcasses of neurons that are killed by disease or injury.” These functions are carried out by three types of Glial cells in the central nervous system…

Depending on the location of the neuron (i.e. the brain or the spinal cord), the length of the axon can be different. For example, the axons in the brain are shorter (Pastorino and Doyle-Portillio, 2015). The axon carries the neural impulse away from the cell body. Several structures to…

Neurons are one of the most important cells in living animals. There are billions of neurons throughout our bodies, especially the brain which is the control house of the body. Neurons are what help us see, hear, taste, and feel sensation. This is all do to a critical phenomenon known as action potential. Action potential is caused by a change in various ions, specifically sodium and potassium. When the neuron is in a resting state with -70mV, there is a great amount of potassium ions inside the…

Excitotoxicity is a pathological process in which neurons are damaged or killed due to the excessive stimulation of certain neurotransmitters such as glutamate. This process of excitotoxic neuronal death is known to contribute to the pathogenesis of brain and/or spinal cord injury associated with multiple human diseases such as Amyotrophic lateral sclerosis (ALS). (2) ALS is a progressive neurodegenerative disease that involves both the upper and lower motor neurons. Glutamate excitotoxicity is…

to a stimulus is coordinated by their central nervous system (CNS). The CNS is made up of the brain and spinal cord. It collects information about changes to the environment and the receptors respond to a stimulus sending impulses along sensory neurons to the central nervous system (Bbc.co.uk, 2018). The peripheral nervous system is made up of all the things outside of the central nervous system. It carries information to and from the central nervous system to the rest of the body, such as…

It also represents a sense organ, such as an eye. The nervous system also contains neuroglial or glial cells which are not neurons and usually outnumber the neurons at a ratio of 10 to 1. The typical peripheral glial cells surrounding the axons are referred to as Schwann cells and are useful in myelination. The microglia, oligodendrocytes, and astrocytes form the central glia and are associated…

to Calbindin (CB) and labels GABAergic neurons In our immunohistochemistry (IHC) experiment, we used anti-Calbindin as our primary antibody, Goat anti-Rabbit 488 IgG as our secondary antibody (“488” meaning that the fluorescent dye is excited at a wavelength of 488nm, fluorescing green), and DAPI-mounting serum as a DNA (nucleus) marker with blue fluorescence for reference against anti-Calbindin-marked GABAergic neurons (Lammel, 2016). While GABAergic-neuron-expressing anti-Calbindin labeled…
