Understanding Brain Structure and Function

The video tutorial uses the analogy of Google Maps to explain brain mapping at various magnifications. It describes the structure and function of nerve cells, focusing on dendrites and axons. The tutorial further explores how synapses facilitate communication between neurons through neurotransmitter release. The goal is to understand the organizational principles of the brain by examining synapses at a high resolution.
