Diagram illustrating the medial surface of the cerebral hemisphere of case 3, in which the isotope was placed above the cingulate sulcus in the rostral part of the superior frontal gyrus and involved the rostral and medial part of area 9. Terminal label was distributed in the rostral two-thirds of the ipsilateral pons and was present in the median nucleus, the paramedian and dorsomedial nuclei, and the NRTP. The contralateral NRTP also had a small projection in between pontine levels IV and V.
