This course explores how synaptic communication in the brain shapes movement, mood, anxiety, and sleep, with a strong emphasis on pharmacological principles and real-world clinical applications. Learners will examine how specific neurotransmitter systems—including dopamine, GABA, and serotonin—regulate neural circuits and behavior, and how disruptions in these systems contribute to common neurological and psychiatric disorders.

Using Parkinson’s disease as a central example, the course investigates the dopaminergic synapse and how molecular changes in dopamine signaling alter motor control. Learners will explore the mechanism of action of L-DOPA, examine alternative therapeutic strategies, and consider patient perspectives on treatments such as deep brain stimulation. The course then turns to anxiety and insomnia, highlighting inhibitory GABA synapses and explaining how benzodiazepines and Z-drugs enhance the brain’s natural braking systems to reduce symptoms and promote sleep. Finally, learners will examine depression through the amine hypothesis, studying how antidepressants such as tricyclics and selective serotonin reuptake inhibitors modify neurotransmitter signaling, as well as emerging treatments such as ketamine. Throughout the course, molecular mechanisms are linked to neural circuits, behavior, and lived patient experiences. This course provides a strong foundation for learners interested in neuroscience, pharmacology, psychology, medicine, and related health sciences.

This course explores the neurobiology and pharmacology of pain and synaptic signaling, with a focus on how drugs targeting specific receptor systems shape perception and behavior. Learners will examine fundamental mechanisms of pain transmission and gain a deeper understanding of G-protein coupled receptors using the opioid receptor as a central example.

The course begins with opioid pharmacology, explaining how opioid receptor agonists produce analgesia at the molecular and circuit levels, and how repeated exposure can lead to tolerance and dependence. Current clinical guidelines and best practices in opioid prescribing are integrated to connect receptor biology with insight into medical decision-making. The course then examines endocannabinoid signaling, highlighting its unique retrograde communication system, endogenous ligands, and receptors. Students will explore the pharmacological effects of THC and synthetic cannabinoids, as well as emerging therapeutic applications and documented health risks. Finally, the course broadens its scope to consider more complex forms of synaptic communication, including silent synapses and tripartite synapses involving neuron–astrocyte interactions. Learners will also be introduced to modern genetic tools used to map neuronal connectivity, emphasizing how advances in technology continue to reshape our understanding of brain circuits. To be successful in this course, learners should have a background in biology. This course provides a strong foundation for students interested in neuroscience, pharmacology, pain research, addiction science, and related biomedical and health fields. Learners should be comfortable with basic cell biology, receptor signaling, and introductory physiology. This course is particularly well suited for learners preparing for careers in medicine, pharmacy, nursing, psychology, biomedical research, or other health-related professions. The course is also appropriate for trainees and healthcare professionals seeking a deeper mechanistic understanding of opioid and cannabinoid pharmacology, especially in the context of pain management and substance use.

This course explores how genetic variation shapes synaptic function, neural circuits, and behavior. Learners will examine how specific gene mutations alter communication between neurons and how these molecular changes scale up to influence cognition, development, and addiction.

The course begins by investigating genetic disruptions of synaptic proteins using Fragile X syndrome as a central example. Learners will explore how mutations in key regulatory genes impair synaptic plasticity, alter neural development, and contribute to neurological symptoms, while also examining current challenges and emerging therapeutic strategies for genetic brain disorders. The course then introduces genetic knockout models as powerful tools for identifying gene function, highlighting research on nicotinic acetylcholine receptor subunits and human genetic mutations that serve as natural experiments in understanding disease mechanisms. In the final module, learners integrate these concepts to study complex synaptic modulation within the brain’s reward pathway, using nicotine addiction and smoking as case studies. The course explores how multiple neurotransmitter systems interact within reward circuits to drive motivation and reinforcement, and concludes with an overview of smoking cessation therapies, emphasizing the pharmacokinetic and pharmacodynamic principles that determine their clinical effectiveness. This course is designed for learners with a background in biology who are interested in neuroscience, genetics, pharmacology, or addiction science. It is especially well suited for learners preparing for careers in medicine, biomedical research, psychology, pharmacy, or other health sciences.
