Much of the central nervous system is involved in visuomotor transformations for goal-
directed gaze and reach movements. These transformations are often described in terms of …

Abstract Abstract CNS Vital Signs (CNSVS) is a computerized neurocognitive test battery
that was developed as a routine clinical screening instrument. It is comprised of seven tests …

It is not known how egocentric visual information (location of a target relative to the self) and
allocentric visual information (location of a target relative to external landmarks) are …

Recent research [eg, Carrozzo, M., Stratta, F., McIntyre, J., & Lacquaniti, F.(2002). Cognitive
allocentric representations of visual space shape pointing errors. Experimental Brain …

Objective: Behavioral studies of spatial navigation in aging indicate that orientation using an
allocentric reference frame (object-centered orientation) is impaired, whereas orientation …

Converging lines of evidence suggest that the presence of non-target landmarks affects the
performance of delayed target-directed movements (eg, Diedrichsen et al. 2004; Sheth and …

How we perceive the visual world as stable and unified suggests the existence of
transsaccadic integration that retains and integrates visual information from one eye fixation …

Transsaccadic integration (TSI) refers to the perceptual integration of visual information
collected across separate gaze fixations. Current theories of TSI disagree on whether it …

A recent study by our group showed that the scaling of reach trajectories to target size is
independent of conscious visual awareness of that intrinsic target property (Binsted et al. in …

The control of goal-directed reaching movements is thought to rely upon egocentric visual
information derived from the visuomotor networks of the dorsal visual pathway. However …
