Here’s a beautiful quote by the great neurophysiologist Sir Charles Sherrington (1857-1952), from his 1941 book Man on His Nature:
Swiftly the brain becomes an enchanted loom where millions of flashing shuttles weave a dissolving pattern, always a meaningful pattern though never an abiding one; a shifting harmony of sub-patterns.
Sherrington made a significant contribution to the discovery of the neuron, and coined the terms neuron and synapse. He was awarded the 1932 Nobel Prize for Physiology or Medicine for his work.
