Ictal theta power at an early suprathreshold treatment outcome. A Ictal theta power versus Ebrain. As the electric field increases, the seizure strength increases (Fp1: t23 = 2.87, p = 0.009; Fp2: t23 = 3.44, p = 0.002). B Change in Depression versus Ictal Theta Power. As the seizure strength increases, depressive symptoms decrease (Fp1: t23 = 2.45, p = 0.05; Fp2: t23 = 2.64, p = 0.01). C Change in Letter Fluency versus ictal theta power. As the seizure strength increases, phonemic fluency worsens (Fp1: t21 = −2.37, p = 0.03; Fp2: t21 = −2.94, p = 0.008). The horizontal dotted line indicates cognitive impairment, while the dotted vertical line is the logistic regression threshold. D Change in Category Fluency versus ictal theta power. As the seizure strength increases, semantic fluency worsens (Fp1: t21 = −2.30, p = 0.03; Fp2: t21 = −2.50, p = 0.02).
