Since the invention of charge-coupled devices (CCD) in late 1969, the potential of the charge-coupling concept for digital memory has been recognized. Applications to image sensing and signal processing requirements have, however, preceded the application of CCD to memory. This occurred because relatively simple charge-coupled devices offered new(More)
The authors describe an experimental model of transient (15 min). unilateral, cerebral ischemia followed by 60 min of reperfusion in anesthetized rats. Zones of non perfusion are recorded and referred to as the "no-reflow phenomenon". The authors believe that vascular changes which interfere with postischemic reperfusion are due to ischemia-induced swelling(More)
