How do neurons communicate with each other?

This course provides a clear and accessible introduction to neurons and neural communication, focusing on how information is transmitted throughout the nervous system.

Designed for beginners, this course breaks down the biology behind behavior into understandable steps. You’ll explore the structure of neurons, how electrical signals are generated, and how chemical messages are passed across synapses. Complex processes like action potentials and neurotransmitter release are explained using visuals, real-world analogies, and simple language—without sacrificing scientific accuracy.

Topics include:

• The structure and function of neurons

• Electrical signaling and action potentials

• The role of myelin and neural speed

• Synapses and chemical communication

• Neurotransmitters and receptor sites

• How agonists, antagonists, and reuptake affect communication

Throughout the course, emphasis is placed on process over memorization—helping you understand how neural communication works and why it matters for behavior, cognition, emotion, and mental health.

This course is ideal for students taking psychology, neuroscience, or biology-related courses, as well as educators and lifelong learners interested in how the brain communicates at the cellular level. No prior background in neuroscience or biology is required.

By the end of the course, you’ll be able to confidently explain how neurons send, receive, and transmit information.
