- Data relating to neurodegeneration or microglia activation for the four control animals is not shown since it was all negative. The correlation between the numbers of times body temperature was ≥41.7 °C, and the relative number of activated microglia within a region was determined using the Spearman rank-order correlation method. The correlation coefficients were as follows: septum, r = 0.781, p = 0.0008; hippocampus, r = 0.850, p < 0.00001; thalamus, r = 0.927, p < 0.00001; parietal cortex, r = 0.652, p < 0.014. The correlation between the numbers of times body temperature was ≥41.7 °C and the relative number of FJc within a region was determined using the Pearson product-moment correlation. The correlation coefficients were as follows: thalamus, r = 0.714, p = 0.0061; parietal cortex, r = 0.546, p = 0.054 not significant
