(A) Average t values for left- versus right-sided angles for each electrode in the left and right brain hemispheres.
(B) Histogram of the contralateral strength index (CSI) for left and right brain hemisphere electrodes.
(C) CSI plotted on an ICBM152 average brain. Each electrode is colored according to its CSI value (red, positive CSI, indicating left angle preference; blue, negative CSI, indicating right angle preference).
(D) Percentages of ipsilateral and contralateral electrodes found in the Heschl’s gyrus, STG, and PT.
***p < 0.001. See also Figure S3.
