AB The  reticular  formation  plays  a  central  role  in  the  regulation  of  the  state  of  consciousness  and  arousal.  It  consists  of  a  complex  network  of  interconnected  circuits  of  neurons  in  the  tegmentum  of  the  brain  stem,  the  lateral  hypothalamic  area,  and  the  medial,  intralaminar,  and  reticular  nuclei  of  the  thalamus  (Fig  18–1).  Many  of  these  neurons  are  serotonergic  (using  serotonin  as  their  neurotransmitter),  or  noradrenergic.  Axons  from  these  nonspecific  thalamic  nuclei  project  to  most  of  the  cerebral  cortex,  where  they  modulate  the  level  of  activity  of  large  numbers  of  neurons.
