Human parietal cortex in action [PDF]
Current Opinion in Neurobiology, 2006 Experiments using functional neuroimaging and transcranial magnetic stimulation in humans have revealed regions of the parietal lobes that are specialized for particular visuomotor actions, such as reaching, grasping and eye movements. In addition, the human parietal cortex is recruited by processing and perception of action-related information, even ...

SPACE AND ATTENTION IN PARIETAL CORTEX [PDF]
Annual Review of Neuroscience, 1999 ▪ Abstract The space around us is represented not once but many times in parietal cortex. These multiple representations encode locations and objects of interest in several egocentric reference frames. Stimulus representations are transformed from the coordinates of receptor surfaces, such as the retina or the cochlea, into the coordinates of ...

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 ...

Reaching for the parietal cortex
Trends in Cognitive Sciences, 1998During reaching movements, sensory signals must be transformed into an appropriate set of motor commands. For visually guided movements, this will involve transforming visual information signalling the spatial position of the target, into a motor plan specifying the sequence of postural changes required to bring the hand to the target.

The evolution of parietal cortex in primates
2018Many of the adaptive changes in the functional organization of parietal cortex of humans emerged in past in the early primates as they depended on visually guided forelimb use to grasp branches and food. Currently, human, apes and some monkeys have four well-defined subdivisions of anterior parietal cortex, areas 3a, 3b, 1 and 2 of Brodmann. In some of

Parietal cortex and spatial cognition
Behavioural Brain Research, 2009The parietal cortex consists of several prominent anatomical regions in the posterior part of the human brain. Although very heterogeneous stimuli and tasks activate parietal brain regions, a large body of empirical evidence points to a particular role of the posterior parietal cortex in spatial cognition.

Action selectivity in parietal and temporal cortex
Cognitive Brain Research, 2005The sensory-action theory proposes that the neural substrates underlying action representations are related to a visuomotor action system encompassing the left ventral premotor cortex, the anterior intraparietal (AIP) and left posterior middle temporal gyrus (LPMT).

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.

Thalamic Projections to Parietal Cortex
Brain, Behavior and Evolution, 1977Thalamic projections to parietal regions of cerebral cortex were investigated in the cat by retrograde degeneration and retrograde transport techniques. Studies of retrograde cellular changes indicate cortically projecting cells in the lateroporterior nucleus (LP), rostral pulvinar (Pul), and the ventral part of the laterodorsal nucleus (LD).
