Abstract

We review a new computational model developed to understand how evidence about stimulus salience in visual search is translated into a saccade command. The model uses the activity of visually responsive neurons in the frontal eye field as evidence for stimulus salience that is accumulated in a network of stochastic accumulators to produce accurate and timely saccades. We discovered that only when the input to the accumulation process was gated could the model account for the variability in search performance and predict the dynamics of movement neuron discharge rates. This union of cognitive modeling and neurophysiology indicates how the visual-motor transformation can occur, and provides a concrete mapping between neuron function and specific cognitive processes.

  • A shift of attention can remain covert or be accompanied by saccades generated by a network including portions of the basal ganglia, superior colliculus, and frontal eye field.

    “A shift of attention can remain covert – generating only an improvement in perceptual discrimination – or can be accompanied by saccades – rapid eye movements that are generated by a network of cortical and subcortical structures that includes portions of the basal ganglia, the superior colliculus and the frontal eye field (Schall et al., 2011; Stanford et al., 2010).”

  • Recent models of sensorimotor transformation for eye movement control propose a process of gated accumulation, whereby accumulation in saccade movement cells is insulated from visual selection until an eye movement becomes appropriate.

    “Recent models synthesizing these findings have proposed a process of gated accumulation, whereby the accumulation of information in saccade movement cells is insulated from visual selection unless (or until) an eye movement becomes appropriate (Lo and Wang, 2006; Purcell et al., 2012; Schall et al., 2011).”

  • Neural responses to target selection can be flexibly linked with action, being coupled with a shift of gaze, a skeletal response, or no immediate motor action.

    “Experiments that dissociate visual selection from motor output show that neural responses to target selection can be flexibly linked with action – for example, being coupled with a shift of gaze, with a skeletal response or with no immediate motor action (Balan et al., 2008; Bisley and Goldberg, 2003; Schall et al., 2011).”

    From Attention, learning, and the value of information (2012) · cites this paper as Schall et al., 2011

  • The capacity for covert attention has been well-established in psychophysical research, and its correlates are found also in the frontal eye field.

    “These neural responses are in some respect not surprising because the capacity for covert attention has been well-established in psychophysical research, and its correlates are found also in the frontal eye field (Schall et al., 2011; Thompson et al., 2005).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
