WebbSaccades are fast eye movement used to shift a person’s gaze from one object to another. Saccades are initiated by the frontal lobes and the burst-velocity signals are then generated from the pontine paramedian reticular formation in the brainstem. The frontal lobe is important in executive functions, attention, and learning. Webb1 sep. 2001 · Roving eye movements are slow, conjugate, lateral, to and fro excursions. These occur when third nerve nuclei and connections are …

WebbNystagmus (ni-stag-muhs) is a condition in which your eyes make rapid, repetitive, uncontrolled movements — such as up and down (vertical nystagmus), side to side (horizontal nystagmus) or in a circle (rotary nystagmus). These eye movements can cause problems with your vision, depth perception, balance and coordination. Webb(fig. 1). A slow eye movement "command" generated in the right occipitoparietal region will result in hori-zontal pursuit to the right with activation of the right lateral rectus and left medial rectus (fig. 3). In addi-tion to saccadic and pursuit eye movements, vestibulo-ocular reflexes are channeled through the PPRF, mak- WebbSaccadic eye movements are supported by a distributed network of cortical and subcortical regions. Saccades are initiated by direct signals sent from the frontal or parietal eye fields (FEFs or PEFs) to the superior colliculus (SC), which drives the oculomotor network (ON) in the brainstem. raw materials ks3
