Differential Vulnerability of Spinal Cord Structures to Anoxia

Concomitant spinal cord and vertebral body infarction is highly associated with aortic pathology: a clinical and magnetic resonance imaging study

“…Thirdly, ''owl's eyes'' sign was found in patients with ASA, but not transverse cord infarctions. Besides, the characteristic sign was often seen in patients receiving MRI at earlier times, suggesting the early stage of cord ischemia is limited to the gray matter of the anterior horn cells, which exhibited the high vulnerability to anoxia/ischemia [9]. Lastly, we noticed that younger patients had a higher incidence of long cord lesions than older ones.…”

Man-in-the-Barrel Syndrome with Combination of Infarctions in the Anterior Spinal Artery and Posterior Inferior Cerebellar Artery Territories

“…As in our patient, clinical and radiological findings suggested only the gray matter of the spinal cord to be affected. Infarction was probably limited to this structure because of its greater susceptibility to ischemia [7] . A collateralization via the pial plexus may also explain the preservation of the pyramidal and the spinothalamic tracts.…”

Slow potentials in the dorsal parts of the isolated spinal cord and their relation to dorsal root potentials

“…The investigations of Bernhard (1953) and others have shown that the latter is built up of several fractions with special characteristics. Experiments with occlusion, asphyxia and pharmacological effects indicate that these fractions have different origin and different longitudinal distribution (Bernhard & Koll, 1953;Gelfan & Tarlov, 1955;Austin & McCouch, 1955). Apparently, presynaptic and postsynaptic fibres as well as internuncial neurones and motoneurones seem to contribute to the dorsal cord potential in situ, but not all of them seem to contribute to the DRP.…”
