Subicular projections to the posterior cingulate cortex in rats
Experimental Neurology, 1977Abstract The subicular cortex and not Ammon's horn has been previously shown to receive afferents from the posterior cingulate cortex. Utilizing the techniques of horseradish peroxidase histochemistry and amino acid autoradiography we present evidence that in the rat the dorsal subicular cortex has a reciprocal connection with the posterior cingulate

Comparative aspects of the primate posterior cingulate cortex
Journal of Comparative Neurology, 1986AbstractCytoarchitecturally defined cortical areas of the posterior cingulate gyrus differ morphometrically among the major taxonomic divisions of primates. Prosimians and anthropoids have different laminar proportions in the isocortical regions (areas 30, 23, and 31); anthropoids have relatively larger outer main laminae and granular layers than ...

The ventral precuneal‐posterior cingulate region as a site of epileptogenicity
Epileptic Disorders, 2022AbstractThe ventral precuneal and posterior cingulate area (VP‐PC) represents a distinct but topographically variable mesial parietal site of epileptogenicity that may manifest as a common temporal lobe‐mediated ictal expression. In a review of records of 62 presumptive epilepsy surgery cases, two cases of primary epileptogenicity expressed within the ...

Quantitative cytoarchitectonics of the posterior cingulate cortex in primates
Journal of Comparative Neurology, 1986AbstractThe cytoarchitecture of four cortical areas within the posterior cingulate region and the differences among them are quantitatively analyzed in 17 primate species. The transition from allocortex (area 29) to isocortex (areas 30, 23, and 31) is characterized by shifts in laminar proportions and cellular densities.

Kindling in the posterior cingulate cortex: electrographic and behavioral characteristics
Electroencephalography and Clinical Neurophysiology, 1990Ictal, postictal and interictal electrical activities were recorded in the posterior cingulate cortex and hippocampus in the rat following kindling stimulations in the cingulate cortex. The afterdischarges (ADs) consisted of fast spikes and slow spike-and-wave of 2-5 Hz.

Risk-sensitive neurons in macaque posterior cingulate cortex
Nature Neuroscience, 2005People and animals often demonstrate strong attraction or aversion to options with uncertain or risky rewards, yet the neural substrate of subjective risk preferences has rarely been investigated. Here we show that monkeys systematically preferred the risky target in a visual gambling task in which they chose between two targets offering the same mean ...

Protein synthesis in the posterior cingulate cortex in Alzheimer's disease
Psychogeriatrics, 2011AbstractBackground: Neuroimaging studies using 18F‐fluoro‐2‐deoxy‐D‐glucose positron emission tomography (FDG‐PET) and single photon emission computed tomography (SPECT) have shown that the posterior cingulate cortex (PCC) is the primary and most prominent area of cerebral metabolic and perfusional decrement in early Alzheimer's disease (AD).

Focal posterior cingulate atrophy in incipient Alzheimer's disease
Neurobiology of Aging, 2010Severe posterior cingulate cortex hypometabolism is a feature of incipient, sporadic Alzheimer's disease (AD). The aim was to test the hypothesis that this region is focally atrophic in very early disease by studying AD patients at the mild cognitive impairment (MCI) stage, and, if so, to determine whether the amount of atrophy was comparable to that ...

The posterior cingulate cortex: Insights from structure and function
2019The posterior cingulate cortex (PCC) (Brodmann areas 23/31) is one of the least well-understood regions of the cortex. The PCC has very high levels of metabolic consumption, and network analyses of functional and structural data suggest it is a core hub in the human connectome; however, contemporary neuroscience lacks a clear account of its functional ...

Localised reductions in gyrification in the posterior cingulate: Schizophrenia and controls
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2007Several authors report changes in the volume and degree of cortical folding in several presumptive regions of schizophrenia patients. However, no research, to our knowledge, has looked for schizophrenia related differences in cortical volume and degree of cortical folding in post-mortem posterior cingulate cortex (PCCx).Brain tissues from 9 people who ...
