Understanding Action Potentials in Neural Networks

The human brain is a highly sophisticated computational network powered by billions of interconnected cells. To understand how this biological supercomputer processes information, you must first understand the fundamental electrical signal that drives it: the action potential. This text-only course guides you through the foundational concepts of bioelectricity, neural communication, and network dynamics. You will transition from understanding a single cellular signal to conceptualizing how entire networks of neurons process complex information, bridging the gap between biology and modern computational concepts. What you'll learn: Understand the electrochemical mechanisms behind resting membrane potentials and action potentials; Explain how electrical signals propagate along axons and transmit across chemical synapses; Analyze the behavior of neural networks and how individual signals integrate to drive complex functions; Compare biological neural networks with artificial neural networks, highlighting the biological inspiration behind modern AI; Explore modern neuromorphic computing concepts and spiking neural network models through clear conceptual explanations. You will start with key terminology and the fundamental biology of the neuron before moving on to signal propagation, synaptic transmission, and network integration. The course concludes with written exercises that connect these biological phenomena to modern computer science paradigms. This course is designed for absolute beginners, curious learners, and aspiring computational neuroscientists, with no prior background in biology or programming required.
