a, Schematic of the task, left. Example spectrograms showing low (left plot) and high (right plot) “cloud of tone” stimuli. b, Coronal sections along the striatum indicating fiber placement positions (tip of the fiber). Note that fibers were inserted in both hemispheres and are mirrored here for illustration purposes. Primary auditory cortex (AUDp) projections (yellow) and primary somatosensory cortex (SSp) projections (blue) are shown in the other hemisphere. c, Horizontal (top) and side view (bottom) of the same histological data. For the horizontal section the recording location depths are collapsed onto a single horizontal atlas image for illustrative purposes. On the side view, the striatum is outlined and the AUDp projections are indicated in grayscale. All error bars represent the standard deviation.
