Cortical Connectivity Maps Reveal Anatomically Distinct Areas in the Parietal Cortex of the Rat

open access: yesFrontiers in Neural Circuits, 2015
A central feature of theories of spatial navigation involves the representation of spatial relationships between objects in complex environments. The parietal cortex has long been linked to the processing of spatial visual information and recent evidence

Outcome contingency selectively affects the neural coding of outcomes but not of tasks [PDF]

open access: yes, 2019
Value-based decision-making is ubiquitous in every-day life, and critically depends on the contingency between choices and their outcomes. Only if outcomes are contingent on our choices can we make meaningful value-based decisions.

NISSL STAIN EXPRESSION IN THE FRONTAL AND PARIETAL CORTICES OF THE NEWBORN MICE AFTER PRENATAL EXPOSURE TO KETAMINE

open access: yesThe Iraqi Journal of Medical Sciences, 2018
Background: Ketamine is an N-methyl-D-aspartate (NMDA) receptor blocking agent, which is used for induction and maintenance of anesthesia. It affects the cerebral cortex and has an impact on learning and memory functions; suggesting that any ...

Multidimensional memory topography in the medial parietal cortex identified from neuroimaging of thousands of daily memory videos

open access: yesNature Communications, 2022
Autobiographical memories are associated with activity in the hippocampus and the parietal cortex. Here the authors characterise the neural substrates for retrieving autobiographical memories from a large dataset, and identify a topography within the ...

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

open access: yesDiagnostics, 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 ...

Posterior parietal cortex and the filtering of distractors [PDF]

open access: greenProceedings of the National Academy of Sciences, 2003
Neural systems for visual processing can focus attention on behaviorally relevant objects, filtering out competing distractors. Neurophysiological studies in animals and brain imaging studies in humans suggest that such filtering depends on top-down inputs to extrastriate visual areas, originating in structures important for attentional control.

Role of medio-dorsal frontal and posterior parietal neurons during auditory detection performance in rats. [PDF]

open access: yesPLoS ONE, 2014
To further characterize the role of frontal and parietal cortices in rat cognition, we recorded action potentials simultaneously from multiple sites in the medio-dorsal frontal cortex and posterior parietal cortex of rats while they performed a two ...

Neural correlates of phonological, orthographic and semantic reading processing in dyslexia [PDF]

open access: yes, 2018
Developmental dyslexia is one of the most prevalent learning disabilities, thought to be associated with dysfunction in the neural systems underlying typical reading acquisition. Neuroimaging research has shown that readers with dyslexia exhibit regional

The relative contributions of frontal and parietal cortex for generalized quantifier comprehension

open access: yesFrontiers in Human Neuroscience, 2014
Quantifiers, like some or few, are frequent in daily language. Linguists posit at least three distinct classes of quantifiers: cardinal quantifiers that rely on numerosity, majority quantifiers that additionally depend on executive resources, and logical

Activity in the Fronto-Parietal and Visual Cortex Is Modulated by Feature-Based Attentional Weighting

open access: yesFrontiers in Neuroscience, 2022
In day-to-day dynamic activities where sensory input is abundant, stimulus representations in the visual cortex are modulated based on their attentional priority.
