Table 5 Results of Spearman correlation tests to assess the association between age, headache frequency (migraine patients only), sensory sensitivity (SPQ Vision score), cortical excitability (first block N1-P1 peak-to-peak amplitude difference), and habituation (Block 12 N1-P1 peak-to-peak amplitude difference – Block 1 N1-P1 peak-to-peak amplitude difference) in Experiment 2
