History-based action selection bias in posterior parietal cortex [PDF]
Nature Communications, 2017 Past outcomes modulate activity in a diverse set of brain regions however their precise influence on decisions is not known. Here the authors show that posterior parietal cortex neurons encode history-related signals between trials and optogenetic ...

Meta-analysis: How does posterior parietal cortex contribute to reasoning?
Frontiers in Human Neuroscience, 2015 Reasoning depends on the contribution of posterior parietal cortex (PPC). But PPC is involved in many basic operations -- including spatial attention, mathematical cognition, working memory, long-term memory, and language -- and the nature of its ...

A cell-type-specific error-correction signal in the posterior parietal cortex. [PDF]
Nature, 2023 A molecularly defined subset of somatostatin-positive inhibitory neurons in the mouse posterior parietal cortex carries a cell-type-specific error-correction signal for navigation.

The human posterior parietal cortex: effective connectome, and its relation to function. [PDF]
Cereb Cortex, 2023 The effective connectivity between 21 regions in the human posterior parietal cortex, and 360 cortical regions was measured in 171 Human Connectome Project (HCP) participants using the HCP atlas, and complemented with functional connectivity and ...

Causal Inference of Body Ownership in the Posterior Parietal Cortex. [PDF]
J Neurosci, 2022 How do we come to sense that a hand in view belongs to our own body or not? Previous studies have suggested that the integration of vision and somatosensation in the frontoparietal areas plays a critical role in the sense of body ownership (i.e., the ...

Posterior Parietal Cortex Plays a Causal Role in Perceptual and Categorical Decisions
Science, 2019 Perceptual decision-making in primates Past investigations of the posterior parietal cortex (PPC) in perceptual decisions tested only its contribution to motor aspects of decisions. However, Zhou and Freedman tested the primate PPC's role in both sensory

Functional Interplay Between Posterior Parietal Cortex and Hippocampus During Detection of Memory Targets and Non-targets [PDF]
Frontiers in Neuroscience, 2020 Posterior parietal cortex is frequently activated during episodic memory retrieval but its role during retrieval and its interactions with the hippocampus are not yet clear.

Posterior parietal cortex dynamically ranks topographic signals via cholinergic influence [PDF]
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.

No Effect of the Right Posterior Parietal Cortex tDCS in Dual-Target Visual Search [PDF]
Frontiers in Psychology, 2018 “Subsequent search misses” represent a decrease in accuracy at detecting a second target in a visual search task. In this study, we tested the possibility to modulate this effect via inhibition of the right posterior parietal cortex trough transcranial ...

Multimodal Representation of Space in the Posterior Parietal Cortex and its use in Planning Movements [PDF]
Annual Review of Neuroscience, 1997 Recent experiments are reviewed that indicate that sensory signals from many modalities, as well as efference copy signals from motor structures, converge in the posterior parietal cortex in order to code the spatial locations of goals for movement ...
