Pons refers to the part of the brain that controls REM and NREM sleep. Pons is a structure in the hindbrain that acts as a neural relay center, a relay station that contains neural fibers that pass signals from one part of the brain to another and facilitating the "crossover" of information between the left side of the body and the right side of the brain and vice versa.

Likewise, Pons is involved in balance and in the processing of both visual and auditory information; a hindbrain structure that is also important in the control of sleep and wakefulness. Pons triggers dreaming and waking from sleep Pons is the link between the hindbrain and the mid-brain; the area on the brainstem that acts as a bridge between the medulla and other structures. It helps control respiration.
