Fig. 3From: A moderate dosage of coffee causes acute retinal capillary perfusion decrease in healthy young individualsEffect on cerebral blood flow as imaged with pCASL-MRI. (A) Frontal lobe map as the region of interest (ROI) in different groups. (a-c) Baseline, 0.5 h, and 2 h after drinking coffee; (d) - (f) Baseline, 0.5 h, and 2 h after drinking water. The yellow arrows demonstrated a significant change in blood flow in these regions. (B) Change in averaged CBF (mL/100 g/min) value extracted from the circled cluster compared to baseline after drinking coffee and plotted by session and time. The vertical lines represent the standard error of the mean. *P < 0.05 vs. baselineBack to article page
