Trivia Question 5 Answer
Santiago Ramon y Cajal was a Spanish physician and scientist with major influence on modern neuroscience (sometimes referred to as the father of modern neuroscience). He won the Nobel prize along with Camillo Golgi in 1906 for work on the microscopic features and structure of the nervous system. While Golgi adamantly maintained that the brain consists of a network of directly connected neurons even at the Nobel Prize ceremony, Cajal correctly stated that neurons have a synaptic cleft and are not directly connected. Cajal also described the unidirectional flow of information from dendrite to axons to these clefts.
Finally, Cajal had at one point wanted to become an artist and his artistic skills served him well while sketching figures of neuroanatomy, histology, and neurons. Golgi deserves credit however for implementing the silver stain, which Cajal used in his study of neurons. Additionally, Golgi was partially correct in that gap junction channels do directly connect some cells in the central nervous system.
