Space Coding in Primate Posterior Parietal Cortex

NeuroImage, 2001
Neuropsychological studies of patients with lesions of right frontal (premotor) or posterior parietal cortex often show severe impairments of attentive sensorimotor behavior. Such patients frequently manifest symptoms like hemispatial neglect or extinction. Interestingly, these behavioral deficits occur across different sensory modalities and are often

Gaze-Dependent Topography in Human Posterior Parietal Cortex [PDF]

Cerebral Cortex, 2013
The brain must convert retinal coordinates into those required for directing an effector. One prominent theory holds that, through a combination of visual and motor/proprioceptive information, head-/body-centered representations are computed within the posterior parietal cortex (PPC).

Flexible adjustment of the effective connectivity between the fronto-parietal and visual regions supports cognitive flexibility

NeuroImage, 2020
Evidence indicates the significance of the fronto-parietal regions and inertia sensory processing from previous trials in cognitive flexibility. However, how flexible cognitive performance is achieved by causal interactions between cortical regions ...

Dance and emotion in posterior parietal cortex: a low-frequency rTMS study [PDF]

, 2012
Background: The neural bases of emotion are most often studied using short non-natural stimuli and assessed using correlational methods. Here we use a brain perturbation approach to make causal inferences between brain activity and emotional reaction to ...

Enhanced Theta-Band Coherence Between Midfrontal and Posterior Parietal Areas Reflects Post-feedback Adjustments in the State of Outcome Uncertainty

Frontiers in Integrative Neuroscience, 2019
Medial frontal cortex is currently viewed as the main hub of the performance monitoring system; upon detection of an error committed, it establishes functional connections with brain regions involved in task performance, thus leading to neural ...

Brain regions that process case: Evidence from basque [PDF]

, 2012
The aim of this event-related fMRI study was to investigate the cortical networks involved in case processing, an operation that is crucial to language comprehension yet whose neural underpinnings are not well-understood.

Thalamocortical connections of rat posterior parietal cortex

Neuroscience Letters, 1992
The neuronal connections of rat posterior parietal cortex (PPC) have been examined using retrograde fluorescent axonal tracers. We have found that PPC receives thalamic input predominantly from the lateral posterior and lateral dorsal nuclei, and not from the ventrobasal nucleus, which projects to the rostrally adjacent hindlimb cortex, or from the ...

Scene-selectivity and retinotopy in medial parietal cortex

Frontiers in Human Neuroscience, 2016
Functional imaging studies in human reliably identify a trio of scene-selective regions, one on each of the lateral (occipital place area, OPA), ventral (parahippocampal place area, PPA), and medial (retrosplenial complex, RSC) cortical surfaces ...

Bottom-up retinotopic organization supports top-down mental imagery [PDF]

, 2013
Finding a path between locations is a routine task in daily life. Mental navigation is often used to plan a route to a destination that is not visible from the current location. We first used functional magnetic resonance imaging (fMRI) and surface-based

Posterior Parietal Cortex Dysfunction Is Central to Working Memory Storage and Broad Cognitive Deficits in Schizophrenia

Journal of Neuroscience, 2018
PFC dysfunction is widely believed to underlie working memory (WM) deficits in people with schizophrenia (PSZ), but few studies have focused on measures of WM storage devoid of manipulation.
