“…They provide a fast orienting response to information of which observers may be perceptually unaware; they may also respond faster than perception. They integrate information across space [46,50], a large range of spatial frequencies [57], and local motion directions (i.e., vector averaging [14,27,5860]). On the other hand, the perceptual system needs to reliably discriminate or categorize visual information.…”

“…Motion perception and pursuit/OFR share anatomical substrates, namely the middle-temporal (MT) area and medial-superior temporal area (MST) [14]. Behavioral studies report similarities in perceptual and pursuit sensitivity in response to motion direction, speed, acceleration, biological motion and illusory motion [literature until 2011 reviewed in 1618, and more recently 27,28]. …”

“…Because older adults’ sensitivity to motion is reduced, it follows that pursuit initiation should also be reduced in older adults, as motion input drives pursuit initiation. Noise in MT neurons may also contribute to slowed pursuit initiation latency in older adults (Niu & Lisberger, 2011). …”

“…By comparing target competition in smooth pursuit for overlapping and non-overlapping targets, Niu and Lisberger (2011) reasoned that there must be two different stages for target competition: one at sensory processing for overlapping targets and one at later sensory-motor processing for non-overlapping targets. In our case, with two overlapping RDKs, the initial competition presumably took place at the sensory processing stage.…”
