| Research Abstract |
To understand the functional role of the oculomotor fastigial nucleus (oFN) for control of saccades, we analyzed the inputs to and the output from the oFN using electrophysiological and anatomical methods. The projection from the oFN terminated densely in the area caudal to the abducens nucleus, but scarcely in the area rostral to it. Neurons in the NRG received strong excitation from the oFN, whereas neurons in the NRPc received almost no excitation. These data suggested that neurons in the NRG that project to the cervical MN are related to motor control of gaze (eye and head). In fact, NRG neurons received strong monosynaptic excitation from the contralateral superior colliculus and disynaptic excitation from the ipsilateral one.
