Axons with limited ipsilateral branches and relatively more extensive contralateral branches. The location of each MSO is indicated by the dashed line. A, Axon 7 in the contralateral MSO has successively longer branches extending caudally (clusters of terminalsa–d), whereas on the ipsilateral side, terminals only were in rostral MSO (e). One collateral branch ended in the area of the lateral trapezoid body (LTB). B, Axon 6 terminated over the length of MSO on the contralateral side (b–d). Branch a was in the medial periolivary area. On the ipsilateral side, one branch terminated in LSO, whereas the other went to the caudal MSO (e). Scale bar, 1 mm.
