Fig. 2From: Acute sleep deprivation enhances susceptibility to the migraine substrate cortical spreading depolarizationEffect of acute sleep deprivation on electrical CSD threshold. CSD threshold was reduced after 12 h but not 6 h of sleep deprivation. Each circle represents the CSD threshold of an individual rat. All controls (6 h controls and 12 h controls) were pooled for statistical analysis, as no significant difference was found between the two control groups. * p < 0.01 vs. controlBack to article page
