Unraveling the mysteries of the brain with the help of a worm

Do we really know how the brain works? In the last several decades, scientists have made great strides in understanding this fantastically complex organ. Scientists now know a great deal about the brain’s cellular neurobiology and have learned much about the brain’s neural connections, and the components that make up these connections. Despite this, a whole host of important questions remain unanswered, and consequently, the brain continues to be one of science’s great, tantalizing mysteries.
