Structure learning and the posterior parietal cortex
Progress in Neurobiology, 2020We propose a theory of structure learning in the primate brain. We argue that the parietal cortex is critical for learning about relations among the objects and categories that populate a visual scene. We suggest that current deep learning models exhibit poor global scene understanding because they fail to perform the relational inferences that occur ...

Coding of intention in the posterior parietal cortex
Nature, 1997To look at or reach for what we see, spatial information from the visual system must be transformed into a motor plan. The posterior parietal cortex (PPC) is well placed to perform this function, because it lies between visual areas, which encode spatial information, and motor cortical areas.

The Posterior Parietal Cortex in Humans and Monkeys
Physiology, 1997The recently reported existence of neurons able to encode visual space in the superior parietal lobule of the monkey brain suggests that human and monkey superior parietal lobules are homologous structures.

Auditory Processing in the Posterior Parietal Cortex
Behavioral and Cognitive Neuroscience Reviews, 2005Goal-directed behavior can be characterized as a dynamic link between a sensory stimulus and a motor act. Neural correlates of many of the intermediate events of goal-directed behavior are found in the posterior parietal cortex. Although the parietal cortex’s role in guiding visual behaviors has received considerable attention, relatively little is ...

Cerebellar input to the posterior parietal cortex in the rat
Brain Research Bulletin, 2002The cerebello-thalamo-parietal projections were investigated in rats by means of a multiple anterograde-retrograde tracing technique. Retrograde fluorescent tracers were injected in different loci of the parietal cortex. Injected areas were verified cytoarchitectonically and confirmed by analyzing the retrograde thalamic labeling pattern obtained ...

Visual vector inversion in the posterior parietal cortex
NeuroReport, 2007In the antisaccade task, a saccade must be triggered towards the mirror location of a visual target. The neural basis required for this visual vector inversion remains unclear, although neuronal activities reflecting this process have been recorded in the monkey lateral intraparietal area.

The role of the posterior parietal cortex in drawing by copying
Neuropsychologia, 2009Impaired ability to draw visually presented figures by copying represents one major manifestation of constructional apraxia (CA). Previous clinical studies have indicated that CA is caused by lesions in the posterior parietal cortex (PPC), but the functional roles of the PPC remain unclear.

The representation of egocentric space in the posterior parietal cortex
Behavioral and Brain Sciences, 1992Abstract The posterior parietal cortex (PPC) is the most likely site where egocentric spatial relationships are represented in the brain. PPC cells receive visual, auditory, somaesthetic, and vestibular sensory inputs; oculomotor, head, limb, and body motor signals; and strong motivational projections from the limbic system.
