Novel Representation of Astasia Associated With Posterior Cingulate Infarction [PDF]

Stroke, 2006
Background and Purpose— The representation elicited in the cingulate motor area has been demonstrated in animals, but remains unclear in humans. In particular, the representation and pathogenic mechanisms of the posterior cingulate cortex are poorly understood, especially in humans.

Temporally Graded Activation of Neocortical Regions in Response to Memories of Different Ages [PDF]

, 2007
The temporally graded memory impairment seen in many neurobehavioral disorders implies different neuroanatomical pathways and/or cognitive mechanisms involved in storage and retrieval of memories of different ages.

The meditative mind: a comprehensive meta-analysis of MRI studies [PDF]

, 2015
Over the past decade mind and body practices, such as yoga and meditation, have raised interest in different scientific fields; in particular, the physiological mechanisms underlying the beneficial effects observed in meditators have been investigated ...

A new tripartite landmark in posterior cingulate cortex [PDF]

, 2021
ABSTRACTUnderstanding brain structure-function relationships, and their development and evolution, is central to neuroscience research. Here, we show that morphological differences in posterior cingulate cortex (PCC), a hub of functional brain networks, predict individual differences in macroanatomical, microstructural, and functional features of PCC ...

Association between cognitive performance and cortical glucose metabolism in patients with mild Alzheimer's disease [PDF]

, 2005
Background: Neuronal and synaptic function in Alzheimer's disease (AD) is measured in vivo by glucose metabolism using positron emission tomography (PET). Objective: We hypothesized that neuronal activation as measured by PET is a more sensitive index of

Task-dependent posterior cingulate activation in mild cognitive impairment [PDF]

NeuroImage, 2006
Neuroimaging research has demonstrated that the posterior cingulate cortex (PCC) is functionally compromised in individuals diagnosed with amnestic mild cognitive impairment (MCI), a major risk factor for the development of Alzheimer's disease (AD). In functional MRI studies with healthy participants, this same region is active during self-appraisal ...

Cognitive training-induced short-term functional and long-term structural plastic change is related to gains in global cognition in healthy older adults: A pilot study

Frontiers in Aging Neuroscience, 2015
Computerized cognitive training (CCT) is a safe and inexpensive intervention to enhance cognitive performance in the elderly. However, the neural underpinning of CCT-induced effects and the timecourse by which such neural changes occur are unknown. Here,

Sub-cortical and brainstem sites associated with chemo-stimulated increases in ventilation in humans [PDF]

, 2010
We investigated the neural basis for spontaneous chemo-stimulated increases in ventilation in awake, healthy humans. Blood oxygen level dependent (BOLD) functional MRI was performed in nine healthy subjects using T2weighted echo planar imaging.

Lower Posterior Cingulate Cortex Glutathione Levels in Obsessive-Compulsive Disorder [PDF]

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2015
Several lines of evidence support the hypothesis that lower cerebral levels of glutathione (GSH), associated with increased oxidative stress, may contribute to obsessive-compulsive disorder (OCD). However, no studies to date have investigated brain GSH levels in individuals with OCD.Twenty-nine individuals with OCD and 25 age-, sex-, and race-matched ...

Consolidation of Complex Events via Reinstatement in Posterior Cingulate Cortex [PDF]

The Journal of Neuroscience, 2015
It is well-established that active rehearsal increases the efficacy of memory consolidation. It is also known that complex events are interpreted with reference to prior knowledge. However, comparatively little attention has been given to the neural underpinnings of these effects.
