Step 1: Explore Your Interests Based On This Week's Lessons

Step 1explore Your Interestsbased Upon This Weeks Lessons Pick A Pa

Explore your interests Based upon this week's lessons, pick a part of the brain you would like to learn more about. Do some background research, finding a minimum of one scholarly journal article from the UMGC Library that provides insight into that part of the brain. From the article, choose 3 or more interesting facts about the part of the brain you are researching and explain the facts. In some detail, using your own words, prepare to present the facts either in your poster or in the text box of this discussion.

Pick an aspect of your research and show it off! [This is your chance to be creative and to express what you are learning in a uniquely informative way - with pictures and images.] What you select to display is up to you.

Here are some examples to get your creative thoughts flowing: Details about the part of the brain, neurotransmitters, lobes (parietal, frontal, and occipital), brain stem (reticular formation, pons, medulla), cerebellum, spinal cord, thalamus, limbic system (hypothalamus, pituitary gland, amygdala, hippocampus), two hemispheres, the cortex (sensory and motor cortex), outcomes from an experiment, importance of some research, favorite insights, graphs, or charts.

Note: You do not have to summarize all of your research. Your objective is to create an interesting visual (think: infographic or Google Slides or even a PowerPoint) so that an outside observer could quickly learn more about your chosen topic.

To build your visual component for this assignment you will need to include the following: 1) At least 2 images (pictures, charts, and graphs all count as images) and 2) Your research reflecting the information you found pertaining to the area of the brain you researched. You will need to integrate your research and include in-text citations when referencing your research. 3) Your reference page in APA format.

For in-text citations (in the body of your poster), cite the author's name and publication date, e.g., (Thompson, 2018). Your full reference list can be placed either at the bottom of the visual or in the textbox of the discussion.

You should put effort into this assignment, but do not feel overwhelmed by creating a visual. There are tools available to make your information look inviting and presentable while not requiring skill or knowledge in graphic design. Think of your visual as making a simplified "poster" about either a part of the brain or a study that teaches about that part of the brain. You may design the poster in any medium you desire, including Microsoft Word, PowerPoint, Photoshop, Google Slides, or some other program. Suggestions include Canva, Infogram, or Easel.ly.

Step 3: Share and Discuss. When your visual is complete, post it here. Following your image, provide a short paragraph describing the image, summarizing what your research shows, and explaining why you found it interesting. Two samples are provided for your review (e.g., hippocampus, pineal gland posters).

Paper For Above instruction

The human brain is an intricate and fascinating organ, comprising numerous structures each with specialized functions. Among these, the hippocampus stands out due to its critical role in memory formation and spatial navigation. This paper explores the hippocampus, highlighting three interesting facts based on scholarly research, visual representations, and their implications for understanding human cognition.

Introduction

The hippocampus, a seahorse-shaped structure located within the medial temporal lobe, is vital for consolidating information from short-term memory to long-term memory (Eichenbaum, 2017). Its significance extends beyond basic memory functions, influencing emotional regulation and spatial awareness. Given its importance, extensive research has been conducted on this brain structure, revealing insights that enhance our understanding of neural processes involved in learning and memory.

Interesting Facts About the Hippocampus

1. Neuroplasticity and Neurogenesis: The hippocampus exhibits a high level of neuroplasticity, meaning it can reorganize itself by forming new neural connections throughout life (Eriksson et al., 1998). Additionally, neurogenesis, or the birth of new neurons, occurs in the adult hippocampus, particularly in the dentate gyrus, which is crucial for learning and memory (Kohler et al., 2016). This ongoing neurogenesis underscores the brain's capacity for adaptation and learning at any age.
2. Impact of Stress and Depression: Chronic stress and depression are linked to diminished hippocampal volume, which correlates with cognitive deficits and emotional dysregulation (McEwen, 2012). Studies using MRI imaging have shown that individuals with prolonged stress or depressive disorders often exhibit hippocampal shrinkage, highlighting its vulnerability to environmental and emotional factors (Lupien et al., 2018).
3. Role in Spatial Navigation: Besides memory, the hippocampus is essential for spatial navigation. It contains "place cells" that activate when an individual is in a specific location within an environment, effectively creating a cognitive map (O'Keefe & Nadel, 1978). This function is fundamental for wayfinding and interacting with our surroundings both in humans and animals.

Visual Representation and Its Significance

The visual poster designed for this research vividly illustrates the hippocampus's location within the brain, its neural pathways involved in memory consolidation, and its vulnerability to stress-related atrophy. Included are two images: a labeled diagram of the brain highlighting the hippocampus, and a graph depicting hippocampal volume comparisons between stressed and non-stressed individuals. These visuals aid in understanding the structural importance and functional dynamics of the hippocampus, making complex neuroscience concepts accessible and engaging for viewers.

Conclusion

The hippocampus is a remarkable brain structure integral to memory, learning, emotional regulation, and spatial navigation. Its plasticity allows lifelong adaptation, yet it remains susceptible to environmental factors such as stress and depression. Through visual and scholarly exploration, we gain a greater appreciation of this structure's multifaceted roles and its relevance to mental health and cognitive functioning.
