Sensory stimuli dominate over rhythmic electrical stimulation in modulating behavior

(a) Individual data showing hit rate as a function of the FM stimulus phase separated by FM frequency. The dashed lines represent the cosine fits. Each plot had a different participant. (b) Gap size threshold as a function of FM frequency. These thresholds were determined using a staircase procedure at the beginning of each session. (c) Hit rate as a function of FM frequency. (d) Strength of behavioral entrainment to the FM stimulus (entAmp-FM) as a function of FM frequency. (e) Optimal FM phase of gap detection performance (prefPhase-FM) for each FM frequency. (f) Preferred FM rate for behavioral entrainment (FM frequency inducing the highest entAmp-FM in (d)). (b–f) Each dot represents a single participant. (b–d) Box plots show the median (horizontal black lines), mean (black cross), 25th and 75th percentiles (box edges), and extreme data points not considered outliers (±2.7σ and 99.3 percentiles, whiskers). Red crosses represent outliers (more than 1.5 times the interquartile range away from the bottom or top of the box). Solid red lines display best fit from the linear model and dashed red lines show the 95% confidence intervals. Numerical data for panels b–d can be found in [32].
