Dose-response curve of MCAs from sham or stroke animals to phenylephrine (PE) at 2 days (A, sham: n=5; ischemic MCA: n=6; non-ischemic MCA: n=6) and 2 weeks (B, sham: n=5; ischemic MCA: n=7; non-ischemic MCA: n=7) after transient MCAO. PE induced a similar dose-dependent vasoconstriction in MCAs from sham animals (Sham MCA), ischemic (Ischemic side MCA), or contralateral hemisphere (Contralateral MCA).
