Yes, this is true.
The mesencephalon, is a small region of the brain that serves as a relay centre for visual, auditory, and motor system information.
It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.
I have attached a diagram for any misunderstandings and for visual representation.
