Parietal cortex and representation of the mental Self [PDF]

Proceedings of the National Academy of Sciences, 2004
For a coherent and meaningful life, conscious self-representation is mandatory. Such explicit “autonoetic consciousness” is thought to emerge by retrieval of memory of personally experienced events (“episodic memory”). During episodic retrieval, functional imaging studies consistently show differential activity in medial prefrontal and medial parietal ...

A Systematic Clinical Framework for Postimplantation Monitoring in Thalamic Neuromodulation: Insights From Twiddler's Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This case described a 25‐year‐old pregnant woman with refractory multifocal epilepsy, diagnosed in 2020 and treated with bilateral thalamic deep brain stimulation (DBS) targeting the centromedian and pulvinar nuclei. Prior to DBS, she experienced daily focal seizures, often progressing to generalized tonic–clonic seizures despite optimal ...

Distinct causal influences of parietal versus frontal areas on human visual cortex: evidence from concurrent TMS-fMRI [PDF]

, 2010
It has often been proposed that regions of the human parietal and/or frontal lobe may modulate activity in visual cortex, for example, during selective attention or saccade preparation.

Episodic memory retrieval, parietal cortex, and the default mode network: Functional and topographic analyses [PDF]

, 2011
The default mode network (DMN) is often considered a functionally homogeneous system that is broadly associated with internally directed cognition (e.g., episodic memory, theory of mind, self-evaluation).

Activation in a frontoparietal cortical network underlies individual differences in the performance of an embedded figures task. [PDF]

PLoS ONE, 2011
The Embedded Figures Test (EFT) requires observers to search for a simple geometric shape hidden inside a more complex figure. Surprisingly, performance in the EFT is negatively correlated with susceptibility to illusions of spatial orientation, such as ...

Time‐Frequency Fingerprint Analysis in SEEG Source‐Space to Identify the Epileptogenic Zone

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This case study highlights the application of seizure fingerprint analysis in the source‐space of stereo‐EEG (SEEG) data to accurately localize the epileptogenic zone (EZ) in patients with complex cortical malformations. A 25‐year‐old female with extensive bilateral perisylvian polymicrogyria (PMG) presented with intractable focal seizures ...

Resting-state connectivity and functional specialization in human medial parieto-occipital cortex [PDF]

, 2015
According to recent models of visuo-spatial processing, the medial parieto-occipital cortex is a crucial node of the dorsal visual stream. Evidence from neurophysiological studies in monkeys has indicated that the parieto-occipital sulcus (POS) contains ...

Fixel‐Based Analysis of Diffusion Imaging as a Quantitative Marker of Disease State in Spinocerebellar Ataxia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxias (SCAs) are a group of genetically heterogeneous neurodegenerative diseases causing progressive deterioration and reduced quality of life. Therapeutic advances have been limited by a lack of sensitive anatomic, functional, or diffusion imaging‐based biomarkers.

The role of the parietal cortex in inhibitory processing in the vertical meridian: Evidence from elderly brain damaged patients

Aging Brain, 2022
We explored the effects of parietal damage on inhibitory effects of visuospatial attention, inhibition of return (IOR) and inhibitory tagging (IT), in the vertical meridian.

Glial Fibrillary Acidic Protein Astrocytopathy Based on a Two‐Center Chinese Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glial fibrillary acidic protein astrocytopathy (GFAP‐A) is a recently defined nosological form belonging to the class of autoimmune inflammatory disorders affecting the central nervous system (CNS). Here, we report the clinical and MRI characteristics, treatment, and prognosis of a GFAP‐A cohort from two centers in China.
