| summary | Smooth pursuit eye movements are an ideal situation to study visual motion processing underlying sensori-motor transformations. Here, I present single-unit responses recorded from middel temporal (MT) and middle superior temporal (MST) area within the superior temporal sulcus as well as from the frontal eye field (FEF) of highly trained rhesus monkeys together with the effects of microstimulations and transient lesions of MST in these animals. The presented results provide evidence that individual neurons in MST code for target movement in extrapersonal space. In addition to the importance of MST for pursuit eye movements, area MST is also involved in the generation of goal-directed hand movements directed towards moving targets. Finally, the role of prediction in order to allow eye movements in sychnrony with predictable target movements is addressed and preliminary single-unit data fromthe FEF are presented. |
