Visual and eye movement functions of the posterior parietal cortex [PDF]

open access: yes, 1989
Lesions of the posterior parietal area in humans produce interesting spatial-perceptual and spatial-behavioral deficits. Among the more important deficits observed are loss of spatial memories, problems representing spatial relations in models or ...

Distinct contributions by frontal and parietal cortices support working memory

open access: yesScientific Reports, 2017
Although subregions of frontal and parietal cortex both contribute and coordinate to support working memory (WM) functions, their distinct contributions remain elusive.

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

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

open access: yes, 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

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.

Neural ensemble decoding reveals a correlate of viewer- to object-centered spatial transformation in monkey parietal cortex [PDF]

open access: yes, 2008
The parietal cortex contains representations of space in multiple coordinate systems including retina-, head-, body-, and world-based systems. Previously, we found that when monkeys are required to perform spatial computations on objects, many neurons in

Functional Connectivity is Altered in Concussed Adolescent Athletes Despite Medical Clearance to Return to Play: A Preliminary Report

open access: yesFrontiers in Neurology, 2016
Recovery following sports related concussion (SRC) is slower and often more complicated in young adolescent athletes than in collegiate players. Further, the clinical decision to return to play is currently based on symptoms and cognitive performance ...

The parietal cortex has a causal role in ambiguity computations in humans.

open access: yesPLoS Biology
Humans often face the challenge of making decisions between ambiguous options. The level of ambiguity in decision-making has been linked to activity in the parietal cortex, but its exact computational role remains elusive. To test the hypothesis that the

Parietal conditioning enhances motor surround inhibition

open access: yesBrain Stimulation, 2020
Background: Motor surround inhibition (mSI) is a phenomenon supportive for executing selective finger movements, wherein synergist muscles are selectively facilitated while surround muscles are inhibited.

Spatial eye–hand coordination during bimanual reaching is not systematically coded in either LIP or PRR [PDF]

open access: yes, 2018
Significance When we reach for something, we also look at it. If we reach for two objects at once, one with each hand, we look first at one and then the other. It is not known which brain areas underlie this coordination.
