<human>:  Who was the first to discover the synapse?
<bot>: The first to discover the synapse was Santiago Ramón y Cajal. He is considered to be the father of modern neuroscience, and he was also the first to describe the structure of the synapse. He discovered that neurons were not simple electrical conductors, but that they had a complex internal structure that was responsible for transmitting impulses. He also discovered the cell nucleus, the structure that contains the genetic material.
