Neuronal Activity and Human Behaviors Assignment Paper

Part 1: Neuronal Activity and Human Behaviors

A particularly important aspect of the nervous system is how neurons “fire,” or act to transmit information. This process is known as the action potential, and is governed by several different factors including neurotransmitters and electrolytes. Action potentials are subject to several laws. For instance, according to the all-or-none principle, an action potential occurs at full strength or not at all. This theory has been a foundation of brain studies and is widely applied in today’s medical field, as well as the computer world and robot industry.Neuronal Activity and Human Behaviors Assignment Paper

Task: Using your text and other resources, study neurotransmission theory. Focus your discussion on answering the following questions:

a. Do you expect there will one day be a “magic drink” with a mixture of chemicals that can make one “smarter,” or prevent neurological and psychological disorders?

b. What neurotransmitters might be involved in creating such a drink?Neuronal Activity and Human Behaviors Assignment Paper

c. What is the likelihood such a drink would be successful? Why or why not?

Remember to support your answers with sources from the text, assigned readings, and outside sources.

Part 2: Research Methods in Biopsychology

To properly understand how biopsychology works, it is important that you understand how researchers test their ideas. Chapter 4, “The Methods and Ethics of Research,” in Brain & Behavior introduces four different research designs:Neuronal Activity and Human Behaviors Assignment Paper

-Naturalistic observation.

-Case study.

-Survey.

-Experiment.

Each of these research designs is used in studying brain and behavior, yet they all have their shortcomings. Find 2–3 peer-reviewed journal articles (published within the last 10 years) that focused on one of the following topics:

-Neurobiology of ecstasy (MDMA) abuse.

-Progression of reading ability in a child diagnosed with autism.

-Effectiveness of a new drug to treat depression.Neuronal Activity and Human Behaviors Assignment Paper

You then selected one of these topics and identified which of the four designs was used in each of the articles you reviewed, such as naturalistic observation, case study, survey, or experiment. In your response to this discussion:

a. Identify your topic of choice.

b. Which of these methods was used in each research article?

c. What were the key variables in the hypothesis or phenomena of interest?

d. Was the hypothesis supported or refuted in the analysis?

e. Were the research questions answered?

f. Explain, based on your understanding of the requirements for a safe and ethical study gained from your readings, whether the study was (or was not) conducted safely and ethically by the authors. Neuronal Activity and Human Behaviors Assignment Paper
