Michael SchollCortical spreading depression Cortical spreading depression Type of evoked potential Cortical spreading depression (CSD) or spreading depolarization (SD) is a wave of electrophysiological hyperactivity followed by a wave of inhibition.[3] Spreading depolarization describes a phenomenon characterized by the appearance of depolarization waves of the neurons and neuroglia[4] that propagates across the cortex at a velocity of 1.5–9.5 mm/min.[5][6][7][8] Animation of cortical spreading depression Cortical spreading depression seen using intrinsic optical signal imaging in gyrencephalic brain. Speed 50x.[1] Hemodynamic changes observed after MCA occlusion in IOS. The video has a speed of 50x to better appreciate the SDs through human eye. Pictures are dynamically subtracted to a reference picture 40 s before. First we see the initial area of change at… (Source: Wikipedia)
