In the monkey brain, two interconnected cortical areas have distinctive neuronal responses to visual, tactile, and auditory stimuli. These areas are the ventral intraparietal area (VIP) and a polysensory zone in the precentral gyrus (PZ). The multimodal neurons in these areas typically respond to objects touching, near, or looming toward the body surface. Electrical stimulation of these areas evokes defensive-like withdrawing or blocking movements. These areas have been suggested to participate… 
Neural Correlates of Personal Space Intrusion
TLDR
Tests of activity-behavior associations revealed that the strength of DIPS-PMv connectivity was correlated with the preferred distance that subjects chose to stand from an unfamiliar person (personal space size), which suggests that this parietal-frontal network plays a role in everyday interactions with others.
Encoding of movement in near extrapersonal space in primate area VIP
TLDR
The findings of this study are in agreement with the behavioral role of area VIP in the representation of movement in near extrapersonal space.
fMRI Adaptation Reveals a Cortical Mechanism for the Coding of Space Near the Hand
TLDR
An fMRI adaptation paradigm on healthy participants is used to reveal areas in the anterior part of the intraparietal sulcus, the inferior parietal lobe (supramarginal gyrus), and the dorsal and ventral portions of the premotor cortex that exhibit selective BOLD adaptation to an object moving near the right hand.
Multimodal Convergence within the Intraparietal Sulcus of the Macaque Monkey
TLDR
Functional magnetic resonance imaging in the monkey is used to provide a bridge between human and monkey studies and highlight strong homologies between macaque and human VIP organization.
Face-infringement space: the frame of reference of the ventral intraparietal area
TLDR
It is demonstrated that VIP includes at least one face-infringement space, which is formalized in terms of the mathematics of graph theory to deduce which combinations are complete as a multidimensional neural structure that provides the organism with a complete set of options regarding objects impacting the face.
Visual looming and receding networks in awake marmosets investigated with fMRI
TLDR
The view that this network that was activated by visual stimuli looming toward or away from the animals using ultra-high-field functional magnetic resonance imaging is supported and the marmoset is a viable model to study visual and multisensory processes by using fMRI to guide further invasive recordings and/or pharmacological manipulations.
Peripersonal space boundaries around the lower limbs
TLDR
This is the first study, to the authors' knowledge, to outline the size of PPS for the lower limbs, and could provide insight into the mechanisms underlying multisensory integration in the lower limb, and add to the current body of knowledge on PPS representations.
Audio-Tactile and Peripersonal Space Processing Around the Trunk in Human Parietal and Temporal Cortex: An Intracranial EEG Study
TLDR
iEEG delineation of PPS processing in humans is represented and it is shown that PPS and multisensory integration happen at similar neural sites and time periods, suggesting that P PS representation is based on a spatial modulation of multisENSory integration.
Looming sensitive cortical regions without V1 input: evidence from a patient with bilateral cortical blindness
TLDR
A patient suffering from complete, bilateral damage to his primary visual cortex is investigated and fMRI data demonstrates that looming motion is processed in the absence of awareness through direct subcortical projections to areas involved in multisensory processing of motion and saliency that bypass V1.
Multisensory and sensorimotor maps.
TLDR
A preliminary yet comprehensive multilayer functional atlas was constructed to specify the relative locations of cortical unisensory, multisensORY, and action representations and the long-term goal is to construct an online surface-based atlas containing layered maps of multiple modalities.

Sensorimotor integration in the precentral gyrus: polysensory neurons and defensive movements.
TLDR
The hypothesis that the polysensory zone in the precentral gyrus contributes to the control of defensive movements in monkeys is supported, and the view that the pre central gyrus can control movement at the level of complex sensorimotor tasks is supported.
Visual–vestibular interactive responses in the macaque ventral intraparietal area (VIP)
TLDR
These results, taken together with data on responses to optic flow stimuli obtained in a parallel study, strongly suggest an involvement of area VIP in the analysis and the encoding of self‐motion.
Ventral intraparietal area of the macaque: congruent visual and somatic response properties.
TLDR
The large proportion of bimodal tactile and visual neurons with congruent response properties in area VIP indicates that there are important functional differences between area VIP and other dorsal stream areas involved in the analysis of motion.
Visual peripersonal space centred on the face in humans.
TLDR
In patients with right hemispheric lesions, visual stimuli delivered in the space near the ipsilesional side of the face extinguished tactile stimuli on the contralesional side (cross-modal visuotactile extinction) to the same extent as did an ipsilsional tactile stimulation (unimodal tactile extinction).
Ventral intraparietal area of the macaque: anatomic location and visual response properties.
TLDR
A discrete area in the depths of the intraparietal sulcus containing neurons with response properties similar to those reported for the middle temporal area is described, called VIP, which suggests that it, like other visual areas in the dorsal stream, may be involved in the analysis of visual motion.
Defensive movements evoked by air puff in monkeys.
TLDR
It is speculated that VIP and PZ may contribute to the control of defensive movements, but that they may emphasize the more spatially specific reactions that occur after startle.
Coding of peripersonal space in inferior premotor cortex (area F4).
TLDR
The functional properties of neurons in the caudal part of inferior area 6 (area F4) in awake monkeys are studied and it is concluded that space is coded differently in areas that control somatic and eye movements.
Super-Flinchers and Nerves of Steel Defensive Movements Altered by Chemical Manipulation of a Cortical Motor Area
TLDR
It is suggested that the polysensory zone of the monkey motor cortex contributes to the ethologically important function of defense of the body.
Space coding by premotor cortex
TLDR
Most inferior area 6 visual neurons code the stimulus position in spatial and not in retinal coordinates, which suggests that these visual neurons are involved in generating the stable body-centered frame of reference necesary for programming visually guided movements.
Multisensory Space Representations in the Macaque Ventral Intraparietal Area
TLDR
It is shown for the first time that macaque area VIP neurons also respond to auditory stimulation, which suggests that area VIP constitutes a part of a neuronal circuit involved in the computation of a modality-invariant representation of external space.
