Evolution of Understanding Neurons and Brain Structure

The discussion explores the historical understanding of neurons and brain composition. It delves into the early investigations by researchers such as Cajal and Golgi, highlighting Cajal's use of the Golgi stain to illustrate neurons in their entirety. The conversation traces the evolution of thought on brain composition, from beliefs in fluid-carrying tubes to the discovery of nerves carrying electricity. The podcast further discusses the development of modern electrophysiological approaches in the early 20th century and the crucial experiments by Hans Berger in recording EEG signals.
