Figure 3. Graph showing slope of pressure-diameter curves for middle cerebral arteries (MCA) exposed to different periods of reperfusion.
Arteries that produced a negative slope are considered myogenic (sham-operated control, 30 minutes and 6 hours of reperfusion), whereas arteries that had a positive slope (≥12 hours of reperfusion) had diminished myogenic behavior. From Cipolla MJ et al., Stroke 2002; 33:2094–2099.
