A. Microscopic images of CA1 area showing nuclei of dead cells. Magenta-colored cells stained with both propidium iodide and SYTOX-blue were considered to have died before electrophysiological recording. Blue-colored cells stained with only SYTOX-blue were assumed to have died due to ischemia-reperfusion injury. Scale bars = 50 μm. B. Two-dimensional scatter plot of cumulative EPSC occurrence and dead cell number per 1 mm of CA1 area. A positive correlation between cumulative EPSC occurrence and surviving cell number was statistically significant (Pearson’s correlation coefficient r = 0.70, n = 11, Student’s t = 2.96, p = 0.016). The line represents an estimated linear regression.
