Figure 2. A schematic pattern of propagation of spreading depression in human brain. Traces recorded from human tissues. Vertical propagation of spreading depression reveals a very slow velocity of DC-negative deflection recorded in human brain tissues obtained during epilepsy surgery. B) SD and cerebrovascular diseases: SD was observed in patients suffering from brain ischemia/infarction, brain haemorrhage, and subarachnoid haemorrhage. The damage to cerebral tissue depends on a complex series of physiological responses and degenerative cellular cascades involving a dynamic interplay among the various cells in the region of damaged tissue. Experimental studies of focal ischemic stroke in animals and human support the concept that there is a core of severe ischemia, the ‘ischemic core’ which is surrounded by a region of [reduced perfusion, the ‘ischemic penumbra’.] |
