Cerebellar infarction after head injury

Motor cortex excitability after cerebellar infarction.

BACKGROUND AND PURPOSE The cerebellum has an influence on motor excitability. We investigated if the location of a cerebellar infarction was crucial for changes of motor cortex excitability and if the electrophysiological findings were correlated with motor performance. METHODS Transcranial magnetic stimulation was applied to study intracortical inhibition (ICI), intracortical facilitation (I...

Brainstem lesions after head injury.

There is little knowledge on the morphology of the brain stem in survivors of head injury, as CT fails to shown brain stem lesions, and neuropathological data is only available from autopsies. As magnetic resonance imaging (MRI) sheds new light on morphological lesions of the brain, the authors investigated 100 patients with a severe head injury. MRI was performed in a prospective study within ...

Patient after Severe Head Injury

Background: The pharmacodynamic differences in time to onset and dissipation of effect of sufentanil, fentanyl, and alfentanil probably result from different rates of blood-brain equilibration. The authors investigated this hypothesis in humans. Methods: After simultaneous central venous bolus application of sufentanil (10 pg), fentanyl (100 pg), and alfentanil (1,000 pg), arterial and jugular ...
