The representation of visual salience in monkey parietal cortex Nature, Vol. 391, No. 6666. (29 January 1998), pp. 481-484, doi:10.1038/35135 by Jacqueline P. Gottlieb, Makoto Kusunoki, Michael E. Goldberg
    abstract = {When natural scenes are viewed, a multitude of objects that are stable in their environments are brought in and out of view by eye movements. The posterior parietal cortex is crucial for the analysis of space, visual attention and movement. Neurons in one of its subdivisions, the lateral intraparietal area ({LIP}), have visual responses to stimuli appearing abruptly at particular retinal locations (their receptive fields). We have tested the responses of {LIP} neurons to stimuli that entered their receptive field by saccades. Neurons had little or no response to stimuli brought into their receptive field by saccades, unless the stimuli were behaviourally significant. We established behavioural significance in two ways: either by making a stable stimulus task-relevant, or by taking advantage of the attentional attraction of an abruptly appearing stimulus. Our results show that under ordinary circumstances the entire visual world is only weakly represented in {LIP}. The visual representation in {LIP} is sparse, with only the most salient or behaviourally relevant objects being strongly represented.},

Gottlieb et al. found that the most salient and the most task-relevant visual stimuli evoke the greatest response in LIP.
