The Pons

The Quick Facts

Location: Area of the hindbrain that sits directly above the medulla
Function: Connects upper and lower parts of the brain

The Pons serves as a message station between several areas of the brain. It helps relay messages from the cortex and the cerebellum. Without the pons, the brain would not be able to function because messages would not be able to be transmitted, or passed along. It also plays a key role in sleep and dreaming, where REM sleep, or the sleeping state where dreaming is most likely to occur, has been proven to originate here, in the pons.
