    • amygdaloid nucleus
  26. reticular formation
    • inhibit, facilitate, modify, and regulate all cortical functions. 
    • integrates all sensorimotor stimuli with internally generated thoughts, emotions and cognition.
    • responsible for maintaining the homeostatic state of the brain . 
  27. 3 subdivisions of midbrain
    • tectum
