e·lec·tro·ce·re·bral si·lence (ECS),

(ē-lek'trō-sĕ-rē'brăl sī'lens),
Flat or isoelectric encephalogram; an electroencephalogram with absence of cerebral activity over 2 mcv from symmetrically placed electrode pairs 10 (or more) cm apart, and with interelectrode resistance between 100-10,000 ohms; if such a record is present for 30 minutes in a clinically brain dead adult and if drug intoxication, hypothermia, and recent hypotension have been excluded, the diagnosis of cerebral death is supported.
An EEG without cerebral activity over 2 µv from symmetrically placed electrode pairs > 10 cm apart, and with interelectrode resistance between 100 and 10,000 ohms; if present for 30 minutes in a clinically brain dead adult—and if drug intoxication, hypothermia, and recent hypotension have been excluded—the diagnosis of cerebral death is supported

Electrocerebral inactivity, flat electroencephalogram, isoelectric encephalogram Neurology An EEG without cerebral activity over 2 µv from symmetrically placed electrode pairs > 10 cm apart, and with interelectrode resistance between 100 and 10,000 ohms; if present for 30 mins in a clinically brain dead adult and if drug intoxication, hypothermia, and recent hypotension have been excluded, the diagnosis of cerebral death is supported.

Two months-1 year: Two clinical examinations and 2 EEGs at least 24 hours apart or one clinical examination (a second clinical examination is not necessary if the initial EEG shows electrocerebral inactivity with a cerebral angiography revealing stopping of the cerebral blood flow).
