title: [Correlation between reflex behavior and EEG in a brain-stem tumor].
abstract: In a female patient with a tumour of the brain stem the e.e.g. showed signs of increasing general functional disorders and additional transient high voltage monographic waves with bilateral frontal and central accentuation, which we regarded as brain stem disturbances. At the same time the authors observed a characteristic inhibition of the amplitude of brain reflexes as well as high phases of a polyphasic stimulation--response potential with stimulation of the tibial nerve. Beside these inhibition phenomena, signs of disinhibition were verified (nociceptive, trigemino-trigeminal reflex, polyphasic disinhibited brain reflex?). The photostimulation was without influence on the sensitivity of motoneurons.
