Spatial representations for action in parietal cortex
Abstract
Parietal cortex contains multiple representations of visual space. Single neurons in area LIP encode attended locations relative to the fovea, while some VIP neurons encode stimulus location relative to the head and some MIP neurons may encode location relative to the arm. These multiple representations are tailored to guide specific kinds of actions: eye movements, head movements and arm movements, respectively. The function of parietal cortex is to signal the location of attended objects relative to the observer. It does so in order to allow the organism to act on its environment. The many different kinds of actions that can be performed are likely to be supported by these very different kinds of spatial representations.

In parietal cortex, ventral intraparietal area, medial intraparietal area, and area 7b exhibit selective coding of near-body objects.
“In the parietal cortex, several subregions exhibited this selective coding, namely the ventral intraparietal area (Colby et al., 1993), the medial intraparietal area (Colby & Duhamel, 1996), and area 7b of the parietal lobe (Graziano & Cooke, 2006).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
