Injections of HRP‐WGA in four cytoarchitectonic subdivisions of the posterior parietal cortex in rhesus monkeys allowed us to examine the major limbic and sensory afferent and efferent connections of each area. Area 7a (the caudal part of the posterior parietal lobe) is reciprocally interconnected with multiple visual‐related areas: the superior temporal polysensory area (STP) in the upper bank of the superior temporal sulcus (STS), visual motion areas in the upper bank of STS, the dorsal… Expand
Organization of the posterior parietal cortex in galagos: II. Ipsilateral cortical connections of physiologically identified zones within anterior sensorimotor region
TLDR
Differences in connections of functionally distinct movement zones of the posterior parietal cortex in galagos identified by intracortical microstimulation with long stimulus trains are consistent with functional parcellation of PPC, and they identify parts of cortical networks that mediate different motor behaviors. Expand
Corticocortical connections of visual, sensorimotor, and multimodal processing areas in the parietal lobe of the macaque monkey
We studied the corticocortical connections of architectonically defined areas of parietal and temporoparietal cortex, with emphasis on areas in the intraparietal sulcus (IPS) that are implicated inExpand
Cortical Connectivity Suggests a Role in Limb Coordination for Macaque Area PE of the Superior Parietal Cortex
TLDR
Results demonstrate that PE, defined as a single architectonic area that contains a topographic map of the body, forms specific connections with somatic and motor fields and hint at a wider variety of motor coordination roles. Expand
Cortical connections of parietal field PEc in the macaque: linking vision and somatic sensation for the control of limb action.
TLDR
The specific anatomical links between PEc and motor and premotor areas that host a representation of the lower limbs, together with the link with vestibular cortex and with areas involved in the analysis of optic flow and spatial navigation, imply a role for PEc in locomotion and coordinated limb movement in the environment.

Chemoarchitectonics and corticocortical terminations within the superior temporal sulcus of the rhesus monkey: Evidence for subdivisions of superior temporal polysensory cortex
TLDR
In addition to STP cortex, parvalbumin and SMI‐32 immunostaining allowed identification of caudal visual areas of the STS, including MT, MST, FST, and V4t. Expand
Uniformity and Diversity of Cortical Projections to Precuneate Areas in the Macaque Monkey: What Defines Area PGm?
TLDR
Analysis of afferent connections supported the existence of two areas: PGm and area 31, compatible with a primary role of PGm in visuospatial cognition (including navigation), while supporting a role for area 31 in sensorimotor planning and coordination. Expand
Rat posterior parietal cortex: topography of corticocortical and thalamic connections
TLDR
The present study concludes that PPC is distinguished by its pattern of cortical connections with the somatic sensory, auditory and visual areas, and with areas Fr2, and VLO/MO, in addition to its exclusive thalamic connectivity with LD, LP and Po. Expand
Efferent cortical connections of multimodal cortex of the superior temporal sulcus in the rhesus monkey
TLDR
The observations indicate that the multimodal region of the superior temporal sulcus has reciprocal connections with the unimodal parasensory association cortices subserving somatosensory, auditory and visual modalities, as well as with other post‐Rolandic higher‐order association areas. Expand
Connections of the medial posterior parietal cortex (area 7m) in the monkey
TLDR
It is discussed in terms of the possibility that area 7m contains a “medial parietal eye field” and belongs to a neural network of oculomotor‐related structures that plays a role in the control of eye movement. Expand
Early coding of reaching: frontal and parietal association connections of parieto‐occipital cortex
TLDR
Area V6A emerges as a potential ‘early’ node of the distributed network underlying visually‐guided reaching, in this network, reciprocal association connections probably impose, through re‐entrant signalling, a recursive property to the operations leading to the composition of eye and hand motor commands.

Limbic and sensory connections of the inferior parietal lobule (area PG) in the rhesus monkey: A study with a new method for horseradish peroxidase histochemistry
TLDR
It is argued that this arrangement of afferent imput may afford a convergence of limbic and sensory information in area PG and that this may subserve a significant function in the process of sensory attention. Expand

TLDR
A cyto- and myeloarchitectonic parcellation of the superior temporal sulcus and surrounding cortex in the rhesus monkey has been correlated with the pattern of afferent cortical connections from ipsilateral temporal, parietal and occipital lobes, and the results suggest a definite organization of this region.

The efferent projections of the neocortex on the lateral convexity of the inferior parietal lobe (IPL) were examined using the anterograde transport of tritiated amino acids to show a striking reciprocal arrangement in the afferent and efferent projection systems of the IPL. Expand

Connections of the parietal lobe

Speculations regarding the associative functions of the parietal lobules at the cortical and subcortical levels are presented, with particular emphasis upon the possible significance of the projections from the inferiorParietal lobule to insular, cingulate and temporal regions of the cortex. Expand
The thalamic afferents to the inferior parietal lobule of the rhesus monkey
TLDR
The inferior parietal lobule of the monkey is the homologous region to the supramarginal and angular gyri in man, subserving language and related cortical functions, and positive cells in the thalamic sections were located by injecting eight monkeys with retrogradely transported HRP. Expand

TLDR
It is speculated that each of these prefrontal projections may carry highly specific information into the hippocampus, whereas the reciprocal projections may allow retrieval by prefrontal cortex of memories stored in the hippocampus. Expand
