From: Alpha sensory stimulation modulates theta phase during speech-print associative learning
a Experimental design. b Response accuracy of paired associative learning for the null, alpha and theta stimulation conditions. Error bars represent ± 1 standard error of the mean. c Amplitude spectrum for the detrended reaction time series as a function of frequency during early exposure (Block 1–3; left) and late consolidation (Block 8–10; right) stages. d Polar plots for the phase distribution at ~4 Hz (left) and ~7 Hz (right) during the early exposure with alpha-rate stimulation.
