Seeing movement in the dark
Article Abstract:
The speed of moving objects as seen through rods and through cones has been compared in order to establish whether normal observers limited to rod vision find it hard to deal with moving objects, as do rod monochromats. It seems that the poorer performance of the night-vision rod system has a retinal explanation, with the slowing possibly being caused by the spatial and temporal averaging in the distal rod visual system. The use of artificial lighting can assist in eliminating the disadvantages of rod-mediate vision.

Antisaccade performance predicted by neuronal activity in the supplementary eye field
Article Abstract:
Random mixed pro- and antisaccade research trials show that spatial selectivity remains constant in visual and movement neurons of the eye. Evidence suggests that voluntary antisaccade instructions take precedence over reflexive glances. The dorsolateral prefrontal cortex, primary frontal eye field and supplementary eye field are thought to result in antisaccade initiation through different mechanisms.
