[Electrographic reflection of vegetative protective and compensatory reactions in craniocerebral trauma].

The authors substantiate the assumption that the presence of high-amplitude superslow potential fluctuations in registration from the skin surface of the head is determined by destabilization of subcortical intercentral relationships which comprises inhibition of stem and activation of posterohypothalamic structures in craniocerebral trauma. The constant potential reacts only to the sharpest period of a severe craniocerebral trauma and reflects acute inflammatory and vascular phenomena on the cortical level in the first 24 hours; maintenance or appearance of increased positive values of the constant potential over one of the hemispheres suggests the presence of an intracranial hematoma above this hemisphere.

[Informational significance of the dynamics of slow electrical processes in craniocerebral injuries].

CNS injuries in brain contusions of a moderate and severe gravity leave lasting EEG traces that can be revealed on examining the patients in the state of sleep and drowsiness, and manifest in the form of pathological oscillations of the slow electrical processes in the second and decasecond intervals. These oscillations have an amplitude of 0.2 to 1.

[Changes in the time required for a simple manual motor response in patients with cranio-cerebral injuries].

In 50 patients with craniocerebral injuries and 50 healthy subjects the duration of motor response of the right and the left hand to light stimulation was examined. It was found that the duration of this response depended on the injury gravity, the localization of the contusion focus in the brain, and the time that had passed since the injury infliction. The method described contributes to specifying the diagnosis of brain concussions and contusions; to determining the affected side of the brain, and to finding out whether the brain activity gets better or worse.
