AIMS To assess the possible role of hypoxia in the formation of axonal bulbs. METHODS Study material comprised sections from 28 brains showing evidence of cerebral hypoxia with no history of head injury, four with a history of head trauma but no evidence of hypoxic change, eight with a history of head trauma and hypoxic change, and four from control brains originally described as "diffuse axo...
Older infants suffer from tears at pontomedullary junction, petechial hemorrhages and cellular necrosis. By one year of age sutures are closed and skull becomes rigid. Glial cell proliferation, synaptic connections, and dendrites arborization progress logarithmically till two years of age. Myelinization begins at first year and progress till 10 year of life. Hence contusions, subarachnoid and e...
Traumatic brain injury (TBI) due to closed mechanisms causes strain injuries to axons that increase in number and severity as injury severity increases. Axons that project up from the brain stem are vulnerable, even in milder concussive injuries, and include axons that participate in key monoaminergic pathways. Although called diffuse axonal injury, the supra-tentorial injury component typicall...
Neurofibromatosis 1 (NF1) is a common disease which is a source of various multisystemic manifestations related either to the accumulation of neurofibromas or to specific developmental abnormalities. The neurofibroma is the hallmark lesion of NF1 and develops from peripheral nerves. However, to date, the description of peripheral neuropathies of NF1 has not been investigated. To examine this qu...
