AbstractGlutamate is the major excitatory neurotransmitter in the human brain and has a central role in both intrinsic and stimulus‐induced activity. We conducted a study in a cohort of healthy, male volunteers in which glutamate levels were measured in the posterior cingulate cortex (PCC) using 1H magnetic resonance spectroscopy at 3T.

A new tripartite landmark in human posterior cingulate cortex
The FASEB Journal, 2020Human brain imaging identifies the posterior cingulate cortex (PCC) as an anatomically and physiologically unique brain region. Structurally, the PCC has been reported as a central network hub of neocortical connectivity. Physiologically, the PCC regularly displays one of the highest metabolic rates in neocortex.

The frequency of multi-unit neuronal firing in response to tonal conditional stimuli increases, and the neuronal responses become discriminative in character, in the anterior and posterior subfields of the cingulate cortex (Brodmann's Area 24 and 29, respectively) during the course of discriminative avoidance conditioning in rabbits.

Posterior Cingulate Neurometabolite Profiles and Clinical Phenotype in Frontotemporal Dementia
Cognitive and Behavioral Neurology, 2006Proton magnetic resonance spectroscopy was used to compare metabolite levels from a posterior cingulate voxel in a group of patients with 2 syndromic subtypes of frontotemporal dementia (n=10) and an age and education-matched group with Alzheimer disease (n=10).

[Posterior Cingulate Cascading Delay Model for Timing Behavior].
Brain and nerve = Shinkei kenkyu no shinpo, 2017We present a novel model for timing behavior. This model is based on the firing property of neurons in the superficial layers of the posterior cingulate granular retrosplenial cortex (GRS) and does not require a unit-time clock. Suppose that event B occurs N seconds after event A and triggers behavior C.

Visual and Saccade-Related Activity in Macaque Posterior Cingulate Cortex
Journal of Neurophysiology, 2004Previous neurophysiological studies have reported that neurons in posterior cingulate cortex (PCC) respond after eye movements, and that these responses may vary with ambient illumination. In monkeys, PCC neurons also respond after the illumination of large visual patterns but not after the illumination of small visual targets on either reflexive ...

The involvement of the posterior cingulate gyrus in phasic pain processing of humans
Neuroscience Letters, 2004Cingulate cortex (CC) processing of phasic pain starts in caudal parts. This is evidenced by electrical brain source analysis (BESA(R)) and current reconstruction imaging (CURRY(R)) which identify the activated neuronal assemblies in the individual brain morphology, including the boundary element method for volume current calculation.
