Named by [Gallese et al 1994]. It’s the rostral/anterior bit of the lateral wall of the of IPS (see picture below), although Lewis and Van Essen put it deeper, along the fundus.
From Lewis and VanEssen:
“AIP neurons have been studied with an experimental paradigm virtually identical to that more recently employed by Murata et al. (1997) in F5. These studies showed that in AIP, as in F5, there are also neurons with motor responses coding specific kinds of grasping or manipulation movements and/or visual responses that appear to be related to the coding of 3D object characteristics (Taira et al. 1990; Sakata et al. 1995). Therefore, as F5, AIP also appears to be involved in visuomotor transformations for grasping (see Jeannerod et al. 1995)." – [Luppino et at 1997]

Input from cIPS (caudal IPS – a Sakata invention I think,
which has “AOS” cells, i.e. cells with Axis Orientation Selectivity.
I think the idea is that these cells are selective for location,
including depth, and orientation of bar-like objects ). "F5 is target of strong projections originating from area AIP. Injections in this parietal area showed that the anterograde and retrograde labellings in the agranular frontal cortex was almost completely confined to F5 and, therefore, the anatomical linkage between these two areas is highly selective and reciprocal. In addition, the differential distribution of the labeling observed in the present study following injections in AIP and LIP, in agreement also with data of Andersen et al. (1990) on LIP connections, support the physiological evidence that AIP is an independent field within the lateral bank of the IP.” –[Luppino et at 1997]

[Binkofski et al 1999] had Ss manipulate “complex
meaningless objects”. They found:
“Significant
activation was found bilaterally in the ventral premotor cortex (Brodmann’s
area 44), in the cortex lining the anterior part of the intraparietal sulcus
(most probably corresponding to monkey anterior intraparietal area, AIP), in the
superior parietal lobule and in the opercular parietal cortex including the
secondary somatosensory area (SII).
[Shikata et al 2001] looked at an orientation discrimination task (orientation of textured planes in visual space) vs a color detection task. They found “cIPS” and “AIP” activity:
