[ noun ] (medicine) a graphical record of electrical activity of the brain; produced by an electroencephalograph
Synonyms Used in print (E. Gellhorn, "Prolegomena to a theory of the emotions"...)Thus , a low intensity of hypothalamic cortical discharges prevails in sleep and a high one during wakefulness , resulting in synchronous EEG potentials in the former and asynchrony in the latter condition . The emotional_states produced by drugs influence the cortical_potentials in a characteristic manner ; synchrony prevails in the EEG of the experimental animal after administration of tranquilizers , but asynchrony after application of analeptic and psychoactive_drugs . It has further been shown that : ( 1 ) an experimental neurosis in its initial stages is associated with a reversible shift in the central autonomic balance ; ( 2 ) drugs altering the hypothalamic balance alter conditioned_reactions ; ( 3 ) in a state of depression , the positive conditioned_stimulus may fail to elicit a conditioned_reaction but cause an increased synchrony instead of the excitatory desynchronizing ( alerting ) effect on the EEG .
