Sorted Single Units for all subjects. The spike waveforms underwent offline spike sorting by the Standard Expectation Maximization method, which is a semi-automatic spike-sorting algorithm offered by the Offline Sorter®. Features used for spike sorting were waveform projection onto the first and second principal component. The total number of recorded units were 41 units (S1L: 8 units, S2R:6 units, S3L:4 units, S3R:7 units, S4R: 5 units, S5L:4 units, S6L:2 units, S6R:5 units).
