Recent data imply that mitochondrial regulation of calcium is critical in the process leading to hypoxic-ischemic brain injury. The aim was to study the subcellular distribution of calcium in correlation with ultrastructural changes after hypoxia-ischemia in neonatal rats. Seven-day-old rats were subjected to permanent unilateral carotid artery ligation and exposure to hypoxia (7.7% oxygen in nitrogen)...
Several investigators have shown the existence of dentate granule cells in ectopic locations within the hilus and molecular layer using both Golgi and retrograde tracing studies but the ultrastructural features and synaptic connections of ectopic granule cells were not previously examined. In the present study, the biocytin retrograde tracing technique was used to label ectopic granule cells following...
