Visuomotor functions of the posterior parietal cortex

open access: yesNeuropsychologia, 2006
In this special issue of Neuropsychologia leading experts in the field discuss controversies and advances in the role of the posterior parietal cortex (PPC) in visuomotor control. The papers are wide-ranging in their scope, covering monkey physiology and anatomy, functional imaging in humans and monkeys as well as transcranial magnetic stimulation and ...

EGR1 Promotes Craniofacial Bone Regeneration via Activation of ALPL⁺PDGFD⁺ Periosteal Stem Cells

open access: yesAdvanced Science, EarlyView.
ALPL+PDGFD+ (AP+) cells are distinct calvarial periosteal stem cells (PeSCs) with diminished postnatal activity. EGR1 drives PeSCs development via BMP signaling through its Znf2 domain and activates them via CTNNB1/WNT10B signaling through its Znf2/3 domains.

Attentional load and sensory competition in human vision: Modulation of fMRI responses by load fixation during task-irrelevant stimulation in the peripheral visual field. [PDF]

open access: yes, 2005
Perceptual suppression of distractors may depend on both endogenous and exogenous factors, such as attentional load of the current task and sensory competition among simultaneous stimuli, respectively. We used functional magnetic resonance imaging (fMRI)

Multimodal Representation of Space in the Posterior Parietal Cortex and its use in Planning Movements [PDF]

open access: yes, 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 ...

Negative schizophrenic symptoms as prefrontal cortex dysfunction: Examination using a task measuring goal neglect

open access: yesNeuroImage: Clinical, 2022
Background: The negative symptoms of schizophrenia have been proposed to reflect prefrontal cortex dysfunction. However, this proposal has not been consistently supported in functional imaging studies, which have also used executive tasks that may not ...

Involvement of the hippocampus, amygdala, entorhinal cortex and posterior parietal cortex in memory consolidation

open access: yesBrazilian Journal of Medical and Biological Research, 1997
A total of 182 young adult male Wistar rats were bilaterally implanted with cannulae into the CA1 region of the dorsal hippocampus and into the amygdaloid nucleus, the entorhinal cortex, and the posterior parietal cortex. After recovery, the animals were

Choroid Plexus Fibroblast–ILC2 Niche Promotes Adult Hippocampal Neurogenesis after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study investigates the role of group 2 innate lymphoid cells (ILC2) in the choroid plexus (ChP) following traumatic brain injury (TBI). ILC2 accumulation alleviates immune infiltration, preserves hippocampal integrity, and improves sensory‐motor and memory functions.

Hemispheric differences in frontal and parietal influences on human occipital cortex: direct confirmation with concurrent TMS-fMRI [PDF]

open access: yes, 2009
We used concurrent TMS-fMRI to test directly for hemispheric differences in causal influences of the right or left fronto-parietal cortex on activity (BOLD signal) in the human occipital cortex.

Aging and the Spectral Properties of Brain Hemodynamics

open access: yesAdvanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

Loss of agency in apraxia [PDF]

open access: yes, 2014
The feeling of acting voluntarily is a fundamental component of human behavior and social life and is usually accompanied by a sense of agency. However, this ability can be impaired in a number of diseases and disorders.
