title: [Electroencephalogram in children during wakefulness and during induced sleep].
abstract: With the purpose of determining the advantages obtained in the electroencephalographic diagnoses of different clinical conditions, 567 electroencephalograms were practiced to 276 patients from the outpatient service of the Hospital Infantil de México of different ages and clinical diagnoses during various stages of wakefulness, spontaneous or sleeping induced with chlorous hydrate and nembutal. In comparative studies carried out under induced sleeping, it was found that bioelectrical abnormalities showed up in a high percentage of the recording obtained during wakefulness, independently of age; thus, it is considered the ideal state. And in cases suggestive of hypsarrhythmia, or where asymmetries are investigated it is convenient to practice recordings under both conditions: wakefulness and sleep.
