Hand Shape Representations in the Human Posterior Parietal Cortex [PDF]

The Journal of Neuroscience, 2015
Humans shape their hands to grasp, manipulate objects, and to communicate. From nonhuman primate studies, we know that visual and motor properties for grasps can be derived from cells in the posterior parietal cortex (PPC).

The mouse posterior parietal cortex: anatomy and functions

Neuroscience Research, 2019
In recent years, the number of studies on decision-making in mice has increased dramatically. Many of these studies focus on the posterior parietal cortex (PPC), an area that has been implicated in sensory and multisensory processing, navigation, motion planning, and decision-making.

The contribution of the human posterior parietal cortex to episodic memory [PDF]

Nature Reviews Neuroscience, 2017
The posterior parietal cortex (PPC) is traditionally associated with attention, perceptual decision making and sensorimotor transformations, but more recent human neuroimaging studies support an additional role in episodic memory retrieval. In this Opinion article, we present a functional-anatomical model of the involvement of the PPC in memory ...

The Posterior Parietal Cortex in Adaptive Visual Processing [PDF]

Trends in Neurosciences, 2018
Although the primate posterior parietal cortex (PPC) has been largely associated with space, attention, and action-related processing, a growing number of studies have reported the direct representation of a diverse array of action-independent nonspatial visual information in the PPC during both perception and visual working memory.

Time course of functional connectivity in primate dorsolateral prefrontal and posterior parietal cortex during working memory. [PDF]

PLoS ONE, 2013
The dorsolateral prefrontal and posterior parietal cortex play critical roles in mediating attention, working memory, and executive function. Despite proposed dynamic modulation of connectivity strength within each area according to task demands, scant ...

Microstructural damage of the posterior corpus callosum contributes to the clinical severity of neglect [PDF]

, 2012
One theory to account for neglect symptoms in patients with right focal damage invokes a release of inhibition of the right parietal cortex over the left parieto-frontal circuits, by disconnection mechanism.

Posterior Parietal Cortex [PDF]

Neuron, 2004
How do we decide how to react to a stimulus or event? To do so requires recognition of the stimulus itself as well as an appreciation of the context within which that stimulus is encountered. In this issue of Neuron, Stoet and Snyder report that neurons in the parietal cortex of monkeys can carry contextual information related to the rules that are ...

Posterior parietal cortex dynamically ranks topographic signals via cholinergic influence

Frontiers in Integrative Neuroscience, 2012
The hypothesis to be discussed in this review is that posterior parietal cortex is directly involved in selecting relevant stimuli and filtering irrelevant distractors.

A Case Report of Early-Onset Alzheimer’s Disease Using ¹⁸F-FDG PET and ¹⁸F-FBB PET

Diagnostics, 2023
We describe a 40-year-old female patient who presented with sleep disturbance, intermittent headache, and gradual subjective cognitive decline. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) showed mild FDG hypometabolism in bilateral ...

The posterior parietal cortex and non-spatial cognition [PDF]

F1000 Biology Reports, 2009
The primate posterior parietal cortex (PPC) processes information related to environmental physical space. The human PPC has apparently expanded not only in size but also in its functional range to encompass certain abstract and higher-order conceptual spaces. In this report, we review various forms of non-spatial representation in the PPC. These forms
