Table 5 Resting and automated electroencephalography (EEG) and reported probiotic effects
Study | EEG paradigm | Measured parameter and effect, probiotic vs placebo |
|---|---|---|
Kelly et al.34 | Resting EEG (eyes closed) | Lower F3 zero crossings, second derivative. No effect on delta, theta 2, alpha 1, alpha 2, or beta waves. No effect on zero crossings, first derivative. (Several differences were observed after both interventions compared to baseline.) |
Kikuchi-Hayakawa et al.47 | Resting EEG (eyes open and eyes closed, 2 min each) | Lower theta power in the resting state, eyes open. No effect on alpha, beta, or alpha/beta ratio in resting state eyes opened or on any wave power with eyes closed. |
Malaguarnera et al.49 | Automated EEG | No effect |
