Spatial transformations for eye–hand coordination

JD Crawford, WP Medendorp… - Journal of …, 2004 - journals.physiology.org
Eye–hand coordination is complex because it involves the visual guidance of both the eyes
and hands, while simultaneously using eye movements to optimize vision. Since only hand …

Circuits for presaccadic visual remapping

HM Rao, JP Mayo, MA Sommer - Journal of …, 2016 - journals.physiology.org
Saccadic eye movements rapidly displace the image of the world that is projected onto the
retinas. In anticipation of each saccade, many neurons in the visual system shift their …

Using a compound gain field to compute a reach plan

SWC Chang, C Papadimitriou, LH Snyder - Neuron, 2009 - cell.com
A gain field, the scaling of a tuned neuronal response by a postural signal, may help support
neuronal computation. Here, we characterize eye and hand position gain fields in the …

Spatial updating and the maintenance of visual constancy

EM Klier, DE Angelaki - Neuroscience, 2008 - Elsevier
Spatial updating is the means by which we keep track of the locations of objects in space
even as we move. Four decades of research have shown that humans and non-human …

Spatial constancy mechanisms in motor control

WP Medendorp - … Transactions of the Royal Society B …, 2011 - royalsocietypublishing.org
The success of the human species in interacting with the environment depends on the ability
to maintain spatial stability despite the continuous changes in sensory and motor inputs …

Computational models of spatial updating in peri-saccadic perception

FH Hamker, M Zirnsak, A Ziesche… - … Transactions of the …, 2011 - royalsocietypublishing.org
Perceptual phenomena that occur around the time of a saccade, such as peri-saccadic
mislocalization or saccadic suppression of displacement, have often been linked to …

A neural mechanism for coordinate transformation predicts pre-saccadic remapping

S Schneegans, G Schöner - Biological cybernetics, 2012 - Springer
Whenever we shift our gaze, any location information encoded in the retinocentric reference
frame that is predominant in the visual system is obliterated. How is spatial memory retained …

Computing vector differences using a gain field‐like mechanism in monkey frontal eye field

CR Cassanello, VP Ferrera - The Journal of physiology, 2007 - Wiley Online Library
Signals related to eye position are essential for visual perception and eye movements, and
are powerful modulators of sensory responses in many regions of the visual and oculomotor …

Distributed population mechanism for the 3-D oculomotor reference frame transformation

MA Smith, JD Crawford - Journal of neurophysiology, 2005 - journals.physiology.org
Human saccades require a nonlinear, eye orientation–dependent reference frame
transformation to transform visual codes to the motor commands for eye muscles. Primate …

Gaze-centered updating of remembered visual space during active whole-body translations

S Van Pelt, WP Medendorp - Journal of neurophysiology, 2007 - journals.physiology.org
Various cortical and sub-cortical brain structures update the gaze-centered coordinates of
remembered stimuli to maintain an accurate representation of visual space across eyes …
