Differential mechanisms of posterior cingulate cortex downregulation and symptom decreases in posttraumatic stress disorder and healthy individuals using real‐time fMRI neurofeedback

Brain and Behavior, 2021
Intrinsic connectivity networks, including the default mode network (DMN), are frequently disrupted in individuals with posttraumatic stress disorder (PTSD). The posterior cingulate cortex (PCC) is the main hub of the posterior DMN, where the therapeutic

Impaired posterior cingulate cortex–parahippocampus connectivity is associated with episodic memory retrieval problems in amnestic mild cognitive impairment

European Journal of Neuroscience, 2021
Episodic memory retention and retrieval decline are the most common impairments observed in amnestic mild cognitive impairment (aMCI) patients who progress to Alzheimer's disease (AD).

The Evaluation of Posterior Cingulate Gyrus by Diffusion Tensor Imaging in Alzheimer’s Disease Patients Compared with Normal Control Subjects

Siriraj Medical Journal, 2019
Objective: Posterior cingulate gyrus atrophy is found in early clinical stage of Alzheimer’s disease (AD) patients.1 Diffusion tensor imaging (DTI) can be used for evaluating microstructure change in brain parenchyma.2 Our objective was to compare the ...

The role of the precuneus and posterior cingulate cortex in the neural routes to action [PDF]

Computer Assisted Surgery, 2019
Neural substrates of action to the object or this specific direct route, however, remain unclear, especially for the connection from the visual pathway to the motor cortex. The study examined this issue by conducting an fMRI experiment, in which two action generation tasks involving pictures of real objects (PA) and the object's nouns (NA) were used ...

The cingulate cortex and limbic systems for emotion, action, and memory [PDF]

, 2019
Evidence is provided for a new conceptualization of the connectivity and functions of the cingulate cortex in emotion, action, and memory. The anterior cingulate cortex receives information from the orbitofrontal cortex about reward and non-reward ...

What about the “Self” is Processed in the Posterior Cingulate Cortex? [PDF]

Frontiers in Human Neuroscience, 2013
In the past decade, neuroimaging research has begun to identify key brain regions involved in self-referential processing, most consistently midline structures such as the posterior cingulate cortex (PCC). The majority of studies have employed cognitive tasks such as judgment about trait adjectives or mind wandering, that have been associated with ...
