BACKGROUND The occurrence of a spontaneous intracerebral hemorrhage in Israel's Prime Minister attracted the scrutiny of local and international media on neurosurgeons as they made therapeutic decisions. In the ensuing public debate, it was suggested that extraordinary measures (surgical treatment) were undertaken only because of the celebrity of the patient. OBJECTIVES To evaluate the criter...

The goal of this study was to determine the role of the pontine lateral parabrachial nucleus (LPBN) in the compensatory responses to blood loss. Conscious unrestrained rats with complete, partial, or sham bilateral ibotenic acid lesions of the LPBN were subjected to a hypotensive 16-ml/kg blood withdrawal via arterial catheter. Complete lesions (LPBNx) encompassed the entire LPBN and extended i...

BACKGROUND Although pure sensory stroke is a relatively common lacunar syndrome, the responsible lesions are often unidentified because of their small size. I reported 21 cases of pure sensory stroke in which the lesions could be identified by head computed tomography and/or magnetic resonance imaging and correlated the clinical findings with the radiological lesions. SUMMARY OF REPORT Eleven...

Ocular bobbing and myoclonus were unusual findings in a patient with central pontine myelinolysis. Pathological findings confirmed the diagnosis of pontine and extrapontine myelinolysis.

abstract background: high resolution ct scan has made early diagnosis of intraventricular hemorrhage (ivh) easier. posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the ct scan. methods: 904 patients were admitted in the nsicu from march 2001 to march 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (gcs les...

Tonic firing of pontine neurons provides excitatory input to the vasomotor centre in the ventrolateral medulla. To increase our understanding of the actions of propofol on CNS neurons controlling the cardiovascular system, we evaluated the effects of propofol on this tonic firing of pontine neurons. The actions of propofol (doses 1-4, respectively: 24 +/- 2, 40 +/- 4, 65 +/- 3 and 104 +/- 3 mg....

BACKGROUND AND PURPOSE Pure hemisensory syndrome can be caused by small strokes occurring in a number of regions, including the thalamus and pons. Differentiation of the pontine sensory syndrome from the thalamic sensory syndrome has generally been made on the basis of distribution of sensory loss and involvement of specific sensory modalities but not without uncertainties and difficulties. Bec...

The developing neurons have been reported to be extremely susceptible to toxicity of NMDA during a restricted developmental period. Pontosubicular neuronal necrosis is a typical type of perinatal human brain lesion and often coexists with other forms of cerebral hypoxic and ischemic injuries. To determine whether functional changes of NMDA receptors related to the susceptibility to NMDA toxicit...
