Abstract
|
|
|
Cerebral blood flow (CBF) and somatosensory evoked potentials (SEP) were studied in 30 cats before and after a right cerebral hemispheric injury.
There was a close correlation between SEP and cerebral blood flow on the in. jured side, and the amplitude was much smaller, perhaps due to direct injury. There was a generalized reduction of CBF to 40% of control Clow on the injury site. If the flow in either hemisphere fell below 15 ㎖/100 gm./min the evoked response disappeared. The blood flow and SEP on the both hemispheres have recovered nearly to normal range after 30 minutes in mannitol treated.
It might be inferred from these results that adequate flow is vital for the preservation and return of electrical activity following the brain injury.
