Next, we analyzed the relationships between the densities of GAD+, parvalbumin+, and calbindin+ interneurons in the parasagittal cortex with the mean EEG power or spectral edge frequency (SEF) during the last 24 h of recovery in the ischemia + normothermia group and the three ischemia + hypothermia groups. Here, PVALB is linked to ischemia.
