The course of corticofacial projections in the human brainstem.

2001

Transcranial magnetic stimulation was used to investigate the corticofacial projections in 53 patients with (n = 28) and without (n = 25) central facial paresis due to unifocal ischaemic lesions at different brainstem levels. Lesion topography documented by MRI studies was correlated with the electrophysiological findings. In the majority of patients the corticofacial fibres travel within the ventromedial base of the pons and cross the midline at the level of the facial nucleus. In some individuals, however, we found evidence that corticolingual fibres form an 'aberrant bundle' in a paralemniscal position at the dorsal edge of the pontine base. In other patients the corticofacial fibres loo…

Emergency MRI in Clinical Peracute Brain Stem and Hemispheric Stroke

1998

We show the capability and results of MRI examinations of peracute brainstem and hemispheric stroke patients in clinical emergency situations. The hypothesis that CT scan is faster and more accurate under this conditions is to be disproved.
