From: Mindfulness based cognitive therapy improves frontal control in bipolar disorder: a pilot EEG study
Grand mean event-related potentials (ERPs) for frontal (F 3 & F 4 ), cingulate (C 3 & C 4 ), and parietal (P 3 & P 4 ) cortices, for the target (letter X) and the cue (letter A) of the continuous performance task. The target ERP yielded no significant differences between controls and bipolar disorder (BD), however tendencies were found over the left frontal cortex (t control vs. bipolar (0-100 ms) = 0.07; t control vs. bipolar (300-400 ms) = 0.07) and right frontal cortex (t control vs. bipolar (300-400 ms) = 0.09). The cue yielded *significant differences between controls and bipolar disorder (BD) over the frontal cortex, as individuals with BD showed a P300-like wave component frontally and Mindfulness based cognitive therapy (MBCT) attenuated the P300-like wave component over the frontal cortices in the bipolar cohort (p < 0.05, t < 0.1, Controlsn = 9, Bipolarn = 12).
