The contributions of Ramon y Cajal and other Spanish authors to hypnosis.

The authors review the most important Spanish contributions to hypnosis during the 19th and 20th centuries, with emphasis on the work of Santiago Ramon y Cajal, winner of the 1906 Nobel Prize in medicine. It is widely accepted that he provided a basic foundation for modern neurosciences with his work on neuronal staining and synaptic transmission. What is missing in most accounts of his work is his longstanding interest and work on hypnosis and anomalous phenomena. This article summarizes that lost legacy, discusses other Spanish hypnosis pioneers and gives a brief overview of current hypnosis activities in Spain.
