PSY 350 Week 1 DQ 1 Methods of Neuroscience Investigation

Methods of Neuroscience Investigation. This discussion is an analysis of the
methods used by neuroscience investigators to study the biological basis of
psychological function. Prior to completing your initial post, complete this week’s
readings in your course textbook and watch Multicellular Organisms and their
Nervous Systems and Discovering the Human Brain: New pathways to
Neuroscience, with Susan Bookheimer, PhD. These materials examine various
investigational methods such as imaging technology, laboratory science techniques,
and special studies that provide information about structure (nervous system
anatomy and cellular structure) and function (nervous system and cellular function).
Evaluate the methods described and select one method you think is the most
powerful or useful for examining the relationship between biology and behavior.
Would this method be best used for basic research, initial diagnosis of a clinical
condition, ongoing patient management, or a combination of these analytic
practices? What part of the nervous system (anatomical structure, function, cellular
chemistry and function) would most likely be studied using this technique?
Elaborate on the investigational method you chose and the target systems or
conditions you have identified to be studied by this technique.

PSY 350 Week 1 DQ 2 Neurotransmitters

Neurotransmitters. This week’s required and recommended materials will cover topics on
neurotransmitters, receptors, neurotransmitter systems, and their role in cognition and behavior
(both normal and abnormal). After reading Chapters 3 and 4 in your course text and viewing

Brain and Nervous System: Your Information Superhighway, The Nervous System: Nerves at
Work, and The Influence of Neurotransmitters complete one of the following options for your
discussion:

Option A: Evaluate one of the neurotransmitters covered in this week’s readings. Explain the role
it plays in modulating responses to a drug of abuse. For example, you could choose the
acetylcholine receptor system and discuss the role this neurotransmitter plays in addiction to
nicotine. In addition to your evaluation of the specific neurotransmitter and its associated
receptor system, provide correlation to the involved neuroanatomical structures, the contribution
of genetics and environment to the development of dependence, tolerance, and addiction to this
substance, as well as clinical treatment interventions.

Option B: Evaluate one of the neurotransmitters covered in this week’s readings. Explain the role
it plays in a neurological or psychological disorder of your choice. For example, you could
choose the dopaminergic system and discuss the role this neurotransmitter has in the
development of schizophrenia. In addition to your evaluation of the specific neurotransmitter and
its associated receptor system, provide a correlation to the involved neuroanatomical structures,
as well as the contribution of genetics and environment to the development and clinical
management of this disorder.
PSY 350 Week 1 Final Project Topic Selection

Final Project Topic Selection. Select a psychological disorder that you would like to study
utilizing a biopsychological approach. For the Final Project, you will provide a detailed
discussion of the psychological disorder that you select this week. While you may refer to other
areas of psychology, the Final Project must focus on the biopsychological causes and treatment
approaches for this disorder. You must utilize current research in this area to evaluate the major
biopsychological theories about this disorder. Your research should also be used to discuss
possible effective biopsychological approaches to treatment that incorporate the biopsychological
causes of the disorder.
Select a disorder from the following list:
a. Schizophrenia
b. Depression

c. Anxiety
d. Substance Abuse (should focus on a single drug of your choice)
e. Autism
f. Neurological disorders
g. Attention-deficit hyperactivity disorder
PSY 350 Week 2 DQ 1 Nervous System

Nervous System. This week, you will examine the major structures of the central and
peripheral nervous systems, as well as the location and function of these structures.
Search the Ashford University Online Library and locate a peer-reviewed research study
that was published within the last five years, which examines the role of one of the
structures reviewed in Chapter 4 of your course text. The research study you identify
should evaluate the function of this structure in either normal or abnormal behavior. Your
response must clearly identify the role of the structure in the identified behavior as well
as your level of agreement with the results of the study and your rationale. Your initial
post should be a minimum of 250 words and utilize at least one peer-reviewed research
study that was published within the last five years.

PSY 350 Week 2 DQ 2 Movement

Movement. This week you were introduced to the role of the central and peripheral
nervous system in controlling movement. The reading also discussed the role of these
systems in movement disorders. One of the most well-known of these movement
disorders is Parkinson’s disease.
Option A: Search the Ashford University Online Library for a peer-reviewed research
study or review published within the last five years that discusses the cause of
Parkinson’s disease. After reading this article and the text, what structure(s) and
neurotransmitter(s) do you think are most important in the development of this disorder?
What does this suggest regarding possible treatment strategies for this disorder? Your
initial post should be a minimum of 250 words and utilize at least one peer-reviewed
research study that was published within the last five years.

Option B: Search the Ashford University Online Library for a peer-reviewed research
study or review that was published within the last five years on the use of stem cells to
treat Parkinson’s disease. Provide a brief summary of this article as part of your
discussion. Do you agree with the argument that the article makes regarding the use of
stem cells? In your discussion, be sure to address the likelihood of this being a
successful treatment strategy. You should also discuss any ethical concerns with this
treatment approach. Your initial post should be a minimum of 250 words and utilize at
least one peer-reviewed research study that was published within the last five years.

PSY 350 Week 3 DQ 1 Sensory Systems

Sensory Systems. This week you were introduced to the sensory systems, which
include the visual, auditory, olfactory, taste, and the body senses. Evolution would
suggest that each sensory system is of significant importance to maintaining the human
organism. For this discussion, imagine you are a professor giving a lecture on the
evolutionary importance of the sensory systems. Prepare a summary of your argument.
Identify which is the most important sensory system for human survival. Your discussion
should also indicate which system is the least important from the perspective of the
“survival of the fittest”. Your initial post should be a minimum of 250 words and utilize at
least one peer-reviewed source that was published within the last five years

PSY 350 Week 3 DQ 2 Consciousness and Sleep

Consciousness and Sleep. This week you were introduced to different but related
topics, of sleep and consciousness. For this discussion, you will focus on a disorder of
one of these topics.
Option A: Identify a peer-reviewed, research study that was published within the last
five years, and focuses on elucidating the cause or a new treatment for one of the
disorders of consciousness covered this week. Be sure to include a discussion of
theories surrounding this disorder and how this research interacts with current theories.
Your initial post should be a minimum of 250 words.
Option B: Identify a peer-reviewed, research study that was published within the last
five years, and focuses on elucidating the cause or a new treatment for one of the
disorders of sleep covered this week. Be sure to include a discussion of theories
surrounding this disorder and how this research interacts with current theories. Your
initial post should be a minimum of 250 words.

PSY 350 Week 3 Final Project Outline

Final Project Outline. This week you will create an outline of the main points of your
Final Project, using the psychological disorder that was selected and approved by the
instructor in Week One. Refer to the Final Project prompt in Week Five for the section
components that must be included in your outline. Each main heading and any
subheadings must include at least a two to three sentence description. You must also
identify a minimum of six peer-reviewed references that were published within the last
five years, which you will use for your Final Project. At least two to three of these should
be research studies. Indicate which section each reference supports within your outline.
Your outline should be at least one to two pages in length (excluding title and reference
pages). It may be longer, depending on how much information you choose to include
and the depth of your descriptions. All citations must be formatted according to APA
guidelines as outlined in the Ashford Writing Center.

PSY 350 Week 4 DQ 1 Gender Testing

Gender Testing. For the discussion this week read the article by Schweinbenz&Cronk
on gender testing of female Olympic athletes. The authors of this article argue that
this is a discriminatory practice that should be abolished. After reading the chapter
on regulation of sexual behavior, do you agree with their argument? Cite specific
sexual development disorders as part of your discussion this week to support the
stance you take. Should females who have androgen insensitivity or other sexual
development disorders be allowed to compete as females? Does it give them an
unfair advantage? Your initial post should be a minimum of 250 words and utilize at
least one peer-reviewed source that was published in the last five years.

PSY 350 Week 4 DQ 2 Eating Disorders

Eating Disorders. Read the article by Wilson et. al. on the behavioral approaches to
the treatment of eating disorders. Choose an eating disorder that is reviewed in this
article and in the text. Review the proposed physiological and behavioral mechanisms
of this disorder. Based on the proposed causes, which treatment strategy reviewed in
this article do you think would be most successful in the treatment of this disorder? Your
initial post should be a minimum of 250 words and utilize at least one peer-reviewed
source published in the last five years.

PSY 350 Week 5 DQ 1 Brain Injury

Brain Injury. View the Brain Injury video (http://searchcenter.intelecomonline.net
What can the brain do to repair itself after traumatic injury? What does the recovery of
the brain typically depend on? How does therapy facilitate in the restoration of lost brain
function? Are there any other approaches, besides physical therapy that could assist in
regaining the brain function lost from a traumatic brain injury? Your initial post should be
a minimum of 250 words and utilize at least one peer-reviewed source that was
published within the last five years

PSY 350 Week 5 DQ 2 Schizophrenia and Smoking

Schizophrenia and Smoking. Doctors have historically noticed that Schizophrenics
smoke at a much higher rate than that of the typical population. This correlation is still
evident today. Review the possible mechanisms of addiction and schizophrenia. Visit
the Ashford University Library to locate at least one peer-reviewed article that was
published within the last five years, which proposes a biological mechanism for the
relationship between Schizophrenia and smoking. How does the data support the
proposed mechanism in the article you chose? What other possible mechanisms might
explain this relationship? Is it possible that biology has nothing to do with the
relationship between smoking and schizophrenia? Your initial post should be a minimum
of 250 words and utilize at least one peer-reviewed source published in the last five
years.

PSY 350 Week 5 Final Paper

Focus of the Final Project
For your Final Project, you will use the psychological disorder that was selected and approved by
the instructor in Week One. In your project, you will provide an overview of the major
biopsychological theories of the disorder as well as a detailed discussion of the biopsychological
causes and treatment approaches for the disorder. The Final Project must utilize peer-reviewed
sources, published within the last five years, and cited according to APA guidelines, to support
and enhance your analysis of the selected disorder. In addition to the general overview of
biopsychological causes and available treatment approaches, locate two to three published
research studies that support a discussion of possible, effective biopsychological approaches to
treatment and incorporate the biopsychological cause of the disorder.

Paper Components:
Introduction
This section should provide a general introduction to the psychological disorder you have
selected that includes the focus of your critique, as well as an overview of the background and
history of the disorder. Additionally, it should provide demographic data that indicates the
prevalence of the disorder in both general and specific populations. Finally, this section should
clearly indicate the direction that the critique will take.
For example, there are many biopsychological theories of alcoholism. In this section you would
express your intent to focus on the role of gamma-Aminobutyric acid (GABA) in alcoholism.
There should then be research on the role of GABA and GABAergic pathways in the
development of this disorder. This is not to say that your paper must focus on only one
biopsychological cause or system, but you should indicate your areas of focus in the
introduction.
Discussion
In this section you will present a detailed discussion of the biopsychologicaletiology and
treatment for the disorder you chose. Indicate if this disorder appears to be genetic in nature or
due to factors in the environment. When discussing the biopsychological causes of this disorder,
be specific. Your discussion should refer not only to specific systems (such as the GABA, noted
previously) but also to the pathways in the brain that are believed to be involved. This section
must utilize current, published research studies to support your discussion. This section should be
the majority of your Final Project.
Conclusion
Provide a concluding summary of your findings regarding your selected disorder. Additionally,
address the possible future research directions that could be taken to further examine the role of
biopsychology in the expression and treatment of this disorder.
The Final Project should contain a minimum of eight to ten double-spaced pages (excluding title
and reference pages) and must be formatted according to APA style as outlined in the Ashford
Writing Center. You must include a minimum of six to eight peer-reviewed sources that were
published within the last five years, and at least two to three of these must be published research
studies.
