Title: Response Variability of Frontal Eye Field Neurons Modulates with Sensory Input and Saccade Preparation but not Visual Search Salience Abbreviated Title: FEF response variability during search Authors:

Discharge rate modulation of frontal eye field (FEF) neurons has been identified with a representation of visual search salience (physical conspicuity and behavioral relevance) and saccade preparation. We tested whether salience or saccade preparation are evident in the trial-to-trial variability of discharge rate. We quantified response variability via the Fano factor in FEF neurons recorded i...

Psychological Review Neurally Constrained Modeling of Perceptual Decision Making

Neural mechanisms of saccade target selection: gated accumulator model of the visual-motor cascade.

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 wh...
