The LIP could bias neural activity in visual cortex towards more efficiently processing relevant stimuli

@serk1 I also thought this was likely, but I couldn't find evidence for this hypothesis

Sabine Kastner (http://www.princeton.edu/~napl/publications.htm) studies this sort of thing and there might be some evidence in one of her papers

@serk1 a quick search through her titles showed no mention of LIP, but thanks for the link

You might want to broaden your search to other parietal areas if you're interested in human visual processing

# Influence of LIP on visual cortex

(Asked by: username_0 on 2016-02-23)

I understand that the lateral intraparietal cortex (LIP) maps [various features of targets](http://www.ncbi.nlm.nih.gov/pubmed/23473325) onto an [eye-centric reference frame](http://www.nature.com/nrn/journal/v3/n7/full/nrn873.html). I also know that this mapping predicts where [visual attention (in the form of saccades) will be directed](http://mahoney.cpmc.columbia.edu/goldberglab/goldbergetal2002.pdf) and [helps maintain the integrity of the mapping](http://www.ncbi.nlm.nih.gov/pubmed/23152627). Finally, I've also noted that the [LIP has various projections to the visual cortex ventral and dorsal stream](http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002072).

What is the function of these projections to the visual cortex? How is the visual cortex influenced by the aforementioned functions of the LIP?
