Struggling to Function with a Neurological Disorder

- When witnessing someone with a Neurological disorder, one counts his/her blessings. People with Neurological disorders struggle to function normally and knowing there is no cure to help them, it is frustrating. Cancer patients do struggle just like the patients with Neurological disorders but there is more patients with Neurological disorders than Cancer patients. The problem is more funding is given to Cancer research as opposed to Neurological research. A Patient with a Neurological disorder can be disabled their whole life without being able to do anything....   [tags: brain, tumor, cancer]

The Nervous System and Alzheimer’s Disease

- The Nervous System is one of the most important and complex system in the human body, because it works as the main control center. It regulates the sensory, integrative and motor function of the body. Everything we do, feel or think is directly linked to the Nervous System. An error in any of these functions could bring negatives consequences such as degenerative diseases later in life. The Nervous System can be divided into two different categories, the central nervous system (CNS), and the peripheral nervous system (PNS)....   [tags: Alzheimer's Disease Essays]

The dream state is quite remarkable and incorporates infinite possibilities for the dreamer within each of us. Nietzsche (1844-1900), a German philosopher, points out that dreams were a puzzle since “the ages of rude beginning of culture” when “man believed that he was discovering a second real world in a dream...

- Sixth Sense: The Vomeronasal Organ "We are all more influenced by smell than we know." (Hercule Poirot) ....Murder in Retrospect, Agatha Christie Biologists have long realized that the noses of most vertebrates actually contain two sensory channels. The first is the familiar olfactory system, which humans possess. The second channel is the vomeronasal complex, a system that has its own separate organs, nerves, and connecting structures in the brain. The function of the vomeronasal system is the detection of pheromones, chemical messengers that carry information between individuals of the same species....   [tags: Biology Essays Research Papers]

Interpretation on Scientific Article about Sense of Smell

- Introduction The sense of smell is what informs an organism of the chemical composition of their surrounding environment. The sense of smell is called olfaction and in humans, it is less developed than in most other mammals. The olfactory system contains epithelial cells that are unique because they are capable of regeneration, unlike most other neurons. The receptors for both taste and smell are called chemoreceptors. They are termed chemoreceptors because they respond to chemicals that are in aqueous solution....   [tags: Biology]

Neural Precursor Cells and Neuro-Regenerative Medicine

- Introduction The adult central nervous system (CNS) is comprised of cells from two distinct lineages- neurons and glial cells. Neurons are the basic building block of CNS that responsible for communicating information via eletro-chemical mechanisms. Glial cells (astrocytes and oligodendrocytes) surround the neurons; provide them support and insulation. “No new neuron after birth” or “the adult human brain cannot regenerate” was the dogma of neurosciences for the past century (1). Recently, this principle has been challenged by the discovery of NPC in both embryonic and adult mammalian nervous system (1, 2)....   [tags: Medicine]

Mechanisms by which a Psychoactive Drug May Exert Influence on Neural Processing

- Psychoactive drugs can be defined as 'chemicals that influence consciousness or behaviour by altering the brains chemical message system' (Schacter et al, 2012). Different drugs can affect the brain in different ways either by intensifying or dulling transmissions. They will alter neural connections by preventing neurotransmitters bonding to the post synaptic neurons in the brain, inhibiting the re-uptake of neurotransmitters or enhancing the bonding and transmission of neurotransmitters. Neurotransmitters are 'chemical messengers that carry signals between neurons in the body' (Cherry K, 2014)....   [tags: behavior medication, ]

Hearing, Listening and Music's Effect on the Brain

- Hearing and listening may seem like synonyms but they refer to different processes. Hearing is a biological process that involves the ear transferring the physical stimuli of sound to neural impulses. Listening is more difficult to quantify as it takes place within the brain. It is generally thought to occur in the temporal lobe and various other regions of the brain but the exact mechanism by which this occurs is unknown. Music has a lot of impact on the brain. It activates several regions of the brain in order to listen to the sound, interpret it as music, and respond to it....   [tags: neurological analysis, neuro science]

- Parkinson’s Disease Introduction Parkinson’s disease is a progressive neurodegenerative disease that mainly affects the elderly, but can also be prevalent in younger generations (“Parkinson’s Disease Foundation,” n.d.). It affects the region of the brain that controls movement, called the substantia nigra (“Parkinson’s Disease Foundation,” n.d.), due to degeneration of dopaminergic neurons in that brain region (“NINDS”, 2015). As the disease progresses, the supply of dopamine that is produced by the brain continues to decrease, leading to the inability of the individual to control their movements (“Parkinson’s Disease Foundation,” n.d.)....   [tags: Parkinson's disease, Dopamine, Basal ganglia]

Comparing and Contrasting Subunits of Memory Storage

- The study of memory has two primary parts: the systems problem of memory and the molecular problem of memory. Along with these two parts, there are two subunits into which memory falls. Implicit memory is the motor and perceptual aspect of our memory while explicit memory is the recall of facts and events. In this lecture, the systems used for memory storage in these two subunits are explained and contrasted. Implicit memory storage differs from explicit memory storage in the way that it occurs in reflex pathways and the cerebellum of organism rather than in a hippocampus and temporal lobe....   [tags: proteins, explicit, synapses]

Reconsidering Alzheimer’s Pathology and Hippocampal Neurogenesis

- Most investigations using transgenic animal models of Alzheimer’s disease (AD) have reported a decrease in hippocampal neurogenesis. Currently, is considered that an impairment in neurogenesis can be an important factor during the onset and progression of AD. Most authors consider hippocampal neurogenesis necessary to maintain hippocampal cognitive abilities, therefore, a damage in the proliferative system has to be functionally detrimental (See references in Mu and Gage, 2011). Most animal models with the familial type mutations that cause AD show that when toxic amyloid beta peptides (Aβ42) are present, hippocampal neurogenesis decreases....   [tags: using transgenic animal models]

The main symptom of epilepsy is a seizure; but in order to accurately diagnose whether a patient has epilepsy or not, an electroencephalogram test has to be carried out, in which the patient’s electrical impulses in the brain is monitored over a period of time (Glass, 2009)....   [tags: Medical Condition, Illnesses, Medicine]
