For example, when there is an impending eye movement, the visual system can anticipate where the target will appear on the retina after the eye movement, and in preparation for this, spatial attention updates and moves to a new location.In subjects instructed to monitor a particular location in a scene while moving the eyes, two different types of spatial-attention shifts have recently been discovered.However, it has so far simulated actual experiments using a simplified one-dimensional design of visual space.To allow for realistic simulations of more complex experiments, we started by extending the original model to operate in two image dimensions.Recently, Ziesche and Hamker (2011) proposed a model of perisaccadic perception to describe the underlying mechanisms of perceiving a stable world during eye movements.

Second, gain fields are assumed to be Gaussian shaped, although measurements of gain fields show more variability.

Furthermore, it is not clear whether the recently observed phenomena of spatial updating of attention relate to the observation of predictive remapping of receptive fields.

In the seminal study of Duhamel, Colby, and Goldberg (1992), a flashed stimulus in the future receptive field—that is, the location of a neuron's receptive field after saccade—evoked a neural response prior to saccade.

We here propose a neuro-computational model located in lateral intraparietal cortex based on a previous model of perisaccadic space perception (Ziesche & Hamker, 2011, 2014).

Our model can account for both types of updating of attention at a neural-systems level.
