The  reticular activation system  (RAS),  one component of the reticular  formation, is responsible for maintaining  wakefulness and alertness and for  filtering out unimportant sensory  information. Other components of the  reticular formation are responsible for  maintaining muscle tone and regulating  visceral motor muscles. The cerebellum consists of a  central region (the vermis) and  two winglike lobes (the cerebellar  hemispheres). Like that of the  cerebrum, the surface of the  cerebellum is convoluted, but the

The limbic system is a network of  neurons that extends over a wide range  of areas of the brain. The limbic system  imposes an emotional aspect to  behaviors, experiences, and memories.
