Timing and velocity randomization similarly affect anticipatory pursuit.
Smooth pursuit eye movements are guided largely by retinal-image motion. To compensate for neural conduction delays, the brain employs a predictive mechanism to generate anticipatory pursuit that precedes target motion (E. Kowler, 1990). A critical question for interpreting neural signals recorded during pursuit concerns how this mechanism is interfaced with sensorimotor processing. It has been...
متن کاملAnticipatory pursuit is influenced by a concurrent timing task.
The ability to predict upcoming events is important to compensate for relatively long sensory-motor delays. When stimuli are temporally regular, their prediction depends on a representation of elapsed time. However, it is well known that the allocation of attention to the timing of an upcoming event alters this representation. The role of attention on the temporal processing component of predic...
متن کاملEvidence for a retinal velocity memory underlying the direction of anticipatory smooth pursuit eye movements.
To compute spatially correct smooth pursuit eye movements, the brain uses both retinal motion and extraretinal signals about the eyes and head in space (Blohm and Lefèvre 2010). However, when smooth eye movements rely solely on memorized target velocity, such as during anticipatory pursuit, it is unknown if this velocity memory also accounts for extraretinal information, such as head roll and o...

37 To compute spatially correct smooth pursuit eye movements, the brain uses both retinal 38 motion and extraretinal signals about the eyes and head in space (Blohm and Lefèvre 2010). 39 However, when smooth eye movements rely solely on memorized target velocity, such as during 40 anticipatory pursuit, it is unknown if this velocity memory also accounts for extraretinal 41 information such as h...
متن کاملEye Fields Stimulation Facilitates Anticipatory Pursuit
Missal, M. and S. J. Heinen. Supplementary eye fields stimulation facilitates anticipatory pursuit. J Neurophysiol 92: 1257–1262, 2004. First published March 10, 2004; 10.1152/jn.01255.2003. Anticipatory movements are motor responses occurring before likely sensory events in contrast to reflexive actions. Anticipatory movements are necessary to compensate for delays present in sensory and motor...
