AB  - Spontaneous  electrical  activity  in  the  superficial  layers  of  the  cerebral  cortex  may  be  recorded  from  the  scalp,  surface,  or  the  substance  of  the  brain  by  electrodes.  When  a  complex  waveform  is  obtained  from  the  scalp,  it  is  called  the  electroencephalogram  (EEG).  In  contrast,  the  waveform  obtained  from  the  surface  of  the  brain  is  known  as  the  electrocorticogram.  Empiric  observations  have  been  well  described  and  consistent  to  distinguish  gross  clinical  states  such  as  consciousness,  unconsciousness,  sleep,  anesthesia,  epilepsy,  and  coma.  However,  the  correlations  of  the  EEG  with  drug  effects,  anesthetic  depth,  and  awareness  are  less  clear  and  consistent.  Though  efforts  have  been  made  about  the  EEG  in  terms  of  the  clinical  status  and  outcome  of  patients,  the  interpretation  of  the  EEG  is  still  largely  operator  dependent,  that  is,  largely  dependent  on  the  experience  and  expertise  of  the  operator.
