1. HERE IS WHERE YOUR PRESENTATION BEGINS Everyday Neurobiology – Effects of Caffeine on Alertness

2. C ontents 01 Presentation Outline: Everyday Neurobiology – Effects of Caffeine on Alertness

3. Presentation Outline: Everyday Neurobiology – Effects of Caffeine on Alertness 01

4. Everyday Neurobiology in Action Title: Everyday Neurobiology in Action Subtitle: Examining the Impact of Caffeine on Alertness and Cognitive Function Your Name and Course Information Title Slide

5. Define everyday neurobiology and its significance Briefly introduce caffeine as a common stimulant used daily State the purpose of the presentation: to analyze which parts of the nervous system are active and how the course material enhances our understanding Everyday Neurobiology Introduction

6. Describe the commonplace scenario: consuming a cup of coffee to boost alertness Note that the example provides a practical window into neurobiology mechanisms Mention observable effects: increased wakefulness, heightened focus, and temporary improvement in cognitive performance Commonplace Scenario The Everyday Example – Caffeine Consumption

7. The brain – processing sensory information, regulating alertness and attention
The spinal cord – transmitting signals between the brain and the body Central Nervous System (CNS) Sensory neurons – conveying external cues (e.g., taste and smell of coffee)
Motor neurons – initiating processes that prepare the body for action Peripheral Nervous System (PNS) Active Components of the Nervous System

8. Cognitive/Alertness Regulation Alertness increases as caffeine antagonizes adenosine receptors in the brain
Improved concentration and execution of complex tasks Memory and Learning Temporary enhancement of short- term memory and focus Autonomic Regulation Influences on heart rate and blood pressure through sympathetic activation Apparent Functions of the Nervous System

9. 01 02 Neurotransmitter Modulation Blocks adenosine receptors, reducing fatigue signals
Increases neuronal firing and release of other neurotransmitters such as dopamine and norepinephrine Hypothalamic-Pituitary-Adrenal Axis Contributes to the “fight- or- flight” response temporarily Neurobiological Mechanisms at Work

10. Detailed discussion of synaptic mechanisms, neurotransmitter release, and receptor dynamics Understanding of Neurotransmission 01 Course modules on cellular neurobiology explain how micro- level interactions scale to impact macro- level behavior Integration of Cellular and System-Level Analysis 02 Practical Application Laboratory exercises and simulations sharpened the understanding of neural communication and functional outcomes 03 Course Insights Applied

11. Normal and Altered Function How the example illustrates both normal and altered function of the nervous system Complex Interactions Observation of how a ubiquitous substance can reveal complex interactions between different nervous system components Course Reflection Reflection on how the course taught the critical analysis of neurobiological events—even those encountered in daily life 01 02 03 Critical Analysis and Reflection

12. Recap Recap the active nervous system components: CNS (brain and spinal cord) and PNS (sensory and motor components) Review the key functions influenced: alertness, memory, autonomic regulation, and cognitive performance Review Conclusion Conclude by emphasizing how academic insights empower everyday observations and deepen understanding of human behavior Summary and Conclusion
