    Neuroscience

    Neuroscience, often called neural science or neurobiology is the study of the nervous system, particularly the brain as the main control of the body and cognitive thinking. It is an interdisciplinary science as it incorporates and uses computer science, math, physics, chemistry and engineering. Neuroscience also looks upon the impact and formation of neurological and neurodevelopmental disorders. There are many branches of modern neuroscience such as behavioral, cellular, cognitive, molecular neuroscience.

    The nervous system is made up of the central nervous system (CNS), this includes the brain and the spinal cord and the peripheral nervous system (PNS), which includes all the associated nerve fibers that connect the body to the CNS. Neurons are specialized cells with a cell body, axon and dendrites wrapped in a myelin sheath that work in conjunction to transfer information in the form of electrochemical signals. The brain itself contains billions of neurons connected to each other in elaborate synaptic networks, and these connections and synapses change in structure over a human life.

    The brain can be divided into the forebrain, midbrain and hindbrain. The forebrain is split into two parts where the diencephalon controls motor functions and processing sensory signals and responses, while the telencephalon is in charge of cognition such as thinking, perceiving and understanding language. The midbrain is in charge of responding to auditory and visual stimuli, whilst the hindbrain is split into the metencephalon and myelencephalon. The metencephalon deals with balance, equilibrium and movement coordination whilst the myelencephalon is in charge of autonomic functions like heart rate and respiratory pathways.

    dementia patients dental care

    Hello I need to have a 5 page paper talking about Dementia. It should talk about the disease the effect on the brain and nervous system, patient's function,..... There are 7 questions need to be covered within 5 pages. (Ideally all 7 questions) references are needed to be addressed at the end of the paper. The questions a

    Pathway of Cerebrospinal Fluid (CFS) Molecule

    Trace the pathway followed by a molecule (cerebrospinal fluid) CFS from the point of production to reabsorption. Be sure to include the following terms: lateral ventricles, foramen of Magendie, choroid plexus, arachnoid granulations, foramen of Lushka, brain, spinal cord, subarachnoid space.

    Neural Basis

    At least as early as Alcmaeon (around 500 B.C.), the brain was identified as the "organ of thought." However, subsequent thinkers continued to believe in the separation of the physical body (including the brain) and the mind (or soul). What were some of the most significant factors that might have prevented general acceptance of

    Social Interactions;Social Intelligence & Learning Styles

    1. Explain how having a negative self-schema affects one's social interactions. How does social intelligence affect one's responses in any given situation? How might a person's self-guides impact his or her perspective on the world? 2. Describe how a person's cognitive style influences learning style. How is personality influe

    The Amygdala, Hippocampus and Emotional Memory

    Within the frontal lobe, the limbic system is one of the major systems and is comprised of both the amygdala and hippocampus, with the former being most involved in memory. It appears as if experiences that evoke marked emotional reactions involve both the hypothalamus and the amygdala -- facilitating the creation of an emotiona

    Schizophrenia - biological basis and symptoms

    What is the biological basis of schizophrenia? Discuss the symptoms that prompt the diagnosis and include the evidence for abnormalities in the ventricles and the results of genetic studies. Compare the experimental evidence for both the "dopamine hypothesis" and the "glutamate hypothesis?" What is your opinion of the underlyin

    Solutions dealing with various disease case studies. These solutions discuss case studies dealing with Polio, senile dementia, a mass found in the brain, and a man found to lack a corpus callosum.

    These solutions discuss case studies dealing with Polio, senile dementia, a mass found in the brain, and a man found to lack a corpus callosum. On performing an autopsy on a 60-year-old man, a medical student found that the man had no corpus callosum. Apparently, the man had functioned well neurologically; his medical histor

    Do organizing effects have an influence on brain development?

    Do organizing effects have an influence on brain development? Are the organizing effects similar in the development of male and female brains? Or are there differences when it comes to the structure or function of the brain between the sexes? Are there any differences in behavior between males and females that can be att

    Functions of the Frontal Lobe of the Brain

    This solution explains the functions carried out by the frontal lobe of the brain. It details behavioral or functional changes that may occur as a result of frontal lobe damage, and explains the rationale for the predicted changes.

    Outline of the visual memory consolidation from sensory input to long-term encoding. Also different forms of forgetting are discussed as well as strategies for avoiding memory lapses.

    Original student question: Trace the memory system from stimuli into long-term memory. Discuss the features of each step and factors that enhance or impede information flow in each step of the process. Explain proactive and retroactive interference and how you might counteract their effects while studying in order to facili

    Ciliary, sphenopalatine, and submandibular ganglia

    Imagine that a mad scientist invents a death-ray that destroys a person's ciliary, sphenopalatine, and submandibular ganglia (and nothing else). Discuss all the symptoms the victim would show. Would the victim die, or would the scientist have to go back to the laboratory to invent a more effective death-ray?

    Brain Growth After Birth/Aging

    Please answer the following: (a) What factors account for brain growth after birth? (b) List some structural brain changes observed with aging

    Embryonic brain vessels

    Name the three primary (embryonic) brain vessels and use clinical terminology to name the resulting adult brain regions.

    Memories and the human brain

    Please describe how different types of amnesia victims help neurologists decode the pathways involved with the processing of "memories" in the human brain. Thank you.

    Cerebellum: Regulation of Motor Control

    Briefly describe the regulation that the cerebellum plays in motor control. Please draw a diagram. Please label and define all lines, arrows, cell types, etc, which are a part of the diagram.
