An ERP study was performed with sudharshan kriya yoga (SKY) in which long-term meditators showed enhanced preattentive processing as indexed by larger mismatch negativity amplitudes both before performing meditation as well as immediately after meditation. In addition, the EEG study with SKY demonstrated changes in theta power as a function of changes in meditative states.

Grand averaged MMN peak amplitudes for meditator and non-meditators (MMN3 is immediately after meditation)

We have also investigated changes in attentional processes with meditation practice with children who meditate compared to children who do not meditate. Different attentional processes were evaluated using the Attention Network Task. Results show that the practice of Transcendental Meditation improves alerting and conflict effects but not orienting. We also investigated cognitive control by looking at conflict adaptation in meditators and controls.
