Abstract
Radioactive amino acids were injected into area 4 in 7 monkeys ( Macaca fascicularis). Ipsilateral corticothalamic projections were traced to Olszewski's nucleus ventralis lateralis pars oralis and pars medialis, the nucleus ventralis posterior lateralis pars oralis, the nucleus ventralis posterior medialis and inferior and to the nucleus reticularis. Some fibers appeared to terminate in the ipsilateral nucleus ventralis lateralis pars caudalis, the nucleus lateralis posterior and the nucleus subthalamicus. A bilateral representation was found in the nucleus centrum medianum, possibly in the paracentralis-centralis lateralis complex and in the paralamellar portion of the nucleus medialis dorsalis. The contralateral labeling was due to fibers crossing via the massa intermedia and was most intense in the cases following injections into the motor face region. A somatotopic arrangement was clearly present in the nucleus ventralis lateralis pars oralis, the nucleus ventralis posterior lateralis pars oralis and the nucleus ventralis posterior medialis. The origin of the projections to the nucleus ventralis posterior medialis needs further clarification.
