abstract = {Spatial attention has been shown to produce non-multiplicative
effects on visual receptive fields(vRFs) in monkey area MT,
including shift and shrinkage. These non-multiplicative effects
have been recently explained by a multiplicative model of
attention. However, Womelsdorf et al. introduced a simplification
leading to two distinct models, one for unmodulated and another
for modulated responses. We provide here a unified account of
both the unmodulated and modulated responses within a single
model. This model relies on a divisive influence of antipreferred
stimuli placed within the receptive fields of the neurons scaled
by spatial attention. This model also allows to reproduce the
observed influence of spatial attention and provides
physiological explanation for the differential shift for the
centre and surround of the receptive field.}
