The neural basis of smooth-pursuit eye movements.

摘要: Smooth-pursuit eye movements are used to stabilize the image of a moving object interest on fovea, thus guaranteeing its high-acuity scrutiny. Such based phylogenetically recent cerebro-ponto-cerebellar pathway that has evolved in parallel with foveal vision. Recent work shown network several cerebrocortical areas directs attention objects three dimensions and reconstructs trajectory target extrapersonal space, thereby integrating various sources multimodal sensory efference copy information, as well cognitive influences such prediction. This cortical is starting point set cerebrofugal projections use different parts dorsal pontine nuclei neighboring rostral nucleus reticularis tegmenti pontis intermediate stations feed two cerebellum, flocculus–paraflocculus posterior vermis, which make mainly complementary contributions control smooth pursuit.
