Cingulate cortex - Wikipedia, the free encyclopedia The cingulate cortex is part of the brain and situated roughly in the middle of the cortex. Anterior cingulate cortex can further be divided in the perigenual anterior cingulate cortex and midcingulate cortex. Four Regions of Cingulate Cortex and Disease Vulnerability, Brent A.

Anterior cingulate cortex - Wikipedia, the free encyclopedia Anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex and includes Brodmann's area 24 (ventral ACC) and 32 (dorsal ACC). Neuroscientists indicate the dorsal anterior cingulate cortex is primarily related to rational cognition while the ventral is more related to emotional cognition. According to the latest research by Alcino Silva and colleagues at the University of California, Los Angeles, the anterior cingulate cortex is responsible for rendering new memories permanent. en.wikipedia.org /wiki/Anterior_cingulate_cortex   (334 words)

Surface Curve Protocol The marginal ramus of the cingulate sulcus defines the posterior border of the paracentral lobule, a medial region of the cerebrum that spans from the precentral to postcentral gyrus. It is easier to visualize it as the anterior segment of three that constitute a Y, with the remaining segments composed by the posterior calcarine (posteior segment of Y) and anterior calcarine (stem or inferior segment of Y). The precuneus is bordered by the marginal ramus of the cingulate sulcus anteriorally and the parieto-occipital sulcus posteriorally. www.loni.ucla.edu /~khayashi/Public/medial_surface   (2672 words)

The Krasnow Institute: Abstracts In 1937 Papez proposed a linkage between cingulate cortex and emotion based on the relay of connections from the hypothalamus to the anterior thalamus and from there to the cingulate cortex. Recent evidence from EEG and fMRI indicates that the anterior cingulate is particularly active when the subject recognizes that he or she has just committed an error in one of these difficult tasks. EEG studies indicate that the anterior cingulate generates a distinct signal which oscillates from 4 to 7 cycles per second and that the amplitude of this signal increases with task difficulty. www.gmu.edu /departments/krasnow/abstracts_frames/abs00/allm0010.htm   (461 words)

[No title] However, the posterior cingulate may also be involved in visual-spatial and memory-cognitive activities, particularly as relates to the body and movement -hence the interconnections with the superior parietal lobe and the parahippocampal gyrus. The anterior cingulate is thus responsible for producing complex emotional-prosodic vocalizations, including, perhaps, the prosodic variations which mothers employ when speaking to their babies and vice versa; i.e. As noted, over the course of evolution the anterior cingulate appears to have contributed to the evolution of the frontal motor-speech areas, whereas the auditory areas in the superior temporal lobe appear to be evolutionary derivatives of as well as richly interconnected with the amygdala (Joseph, 1999e). www.brainmind.com /Cingulate.html   (6027 words)

Medial Lines Protocol The second scenario involves an anterior cingulate sulcus that begins superior to the plane prescribed by the inferior splenium and posterior rostrum. A double parallel anterior cingulate sulcus is present when there are two sulci that are present, either intersecting the superior rostral sulcus or curving inferiorally and posteriorally near the genu of the corpus callosum. It is easier to visualize it as the anterior segment of three that constitute a Y, with the remaining segments composed by the posterior calcarine (posterior segment of Y) and anterior calcarine (stem or inferior segment of Y). www.loni.ucla.edu /~esowell/edevel/MedialLinesProtocol.htm   (3109 words)

Last check: 2007-10-08) Ipsilateral connections of the anterior cingulate cortex with the frontal and medial temporal cortices in the macaque monkey. The present study was attempted to study ipsilateral corticocortical connections of the anterior part (area 24) of the cingulate cortex of the macaque monkey by means of wheat germ agglutinin-conjugated peroxidase (WGA-HRP) method. The results obtained from these monkeys indicate that areas 24a and 24b in the anterior part of the cingulate cortex are reciprocally connected with the prefrontal, premotor, and motor cortical regions, and also with the medial temporal cortical regions. brainmeta.com /neuroanat/a1.html   (296 words)

FuturePundit: Long Term Memories Processed By Anterior Cingulate Alcino J. Silva at UCLA, Paul Frankland (now at University of Toronto) and coworkers at UCLA have discovered that the anterior cingulate of the cortex of the brain plays a key role in the formation and recall of long term memories. "We were fascinated to see the anterior cingulate switch on when we tested the normal mice for distant memory, but not when we tested them for recent memory," Silva said. The scientists discovered that disabling the anterior cingulate did not disrupt the animals' memory of the cage at one and three days after training, but did interrupt the mice's memory of the cage at 18 and 36 days after training. www.futurepundit.com /archives/002097.html   (939 words)

Last check: 2007-10-08) Although the anterior cingulate is active during symptom provocation in PTSD patients, this effect is not really representative of anything specific to this anxiety disorder. Unfortunately, the anterior cingulate is an area that is highly active during almost all PET studies involving cognition or psychiatric conditions. However, this doesn't mean that the anterior cingulate isn't crucial to a PTSD response or to a psilocybin response. www.maps.org /pipermail/maps_forum/1999-November/002173.html   (199 words)

Redefining the Self, Drs Hal and Sidra Stone PET scans (positron emission tomography), for example, are being used to visualize (in vivo) the metabolic substrate of executive attention (located within the anterior cingulate cortex) as well as other attentional and psychological states. They have found that the anterior cingulate cortex has complex and rich inputs from both the emotional brain and higher cortical centers. In addition, Heilman (1997) in his review of the anterior cingulate cortex points out that conflict monitoring, response selection and initiation of action are all critical components of the function of the anterior cingulate cortex. www.delos-inc.com /Reading_Room/Articles/redefiningTheSelf.htm   (1806 words)

NOVA Online | Everest | Stroop Test Description This region lies between the right and left halves of the frontal portion of the brain, and is involved in a wide range of thought processes and emotional responses. Although the functions of the anterior cingulate are very complex, broadly speaking it acts as a conduit between lower, more impulse-driven brain regions and higher, more rationally-driven behaviors. Perhaps the Stroop effect's sensitivity to changes in brain function is related to its association with the anterior cingulate. www.pbs.org /wgbh/nova/everest/exposure/stroopdesc.html   (175 words)

The Effects of Muscarinic Cholinergic Receptor Blockade in the Rat Anterior Cingulate and   (Site not responding. Last check: 2007-10-08) Infusions of scopolamine (1,5, and 10 mg), a muscarinic cholinergic antagonist, into the prelimbic/infralimbic cortices, but not the anterior cingulate cortex, significantly impaired spatial working memory in a lag- and dose-dependent manner. The deficit induced by scopolamine (10 mg) was attenuated by concomitant intra- prelimbic/infralimbic injections of oxotremorine (2 mg), a muscarinic cholinergic agonist. These findings suggest that muscarinic transmission in the prelimbic/infralimbic cortices but not the anterior cingulate cortex, is important for spatial working memory. www.uic.edu /depts/psch/abstracts/ragab05.html   (244 words)

BioMed Central | Full text | Decreases in blood perfusion of the anterior cingulate gyri in Anorexia Nervosa ... SPM analysis of SPECT images revealed that the blood flow of the bilateral anterior parts of cingulate gyri (ACC: Brodmann's areas 24) and parts of frontal regions (parts of areas 8, 9,10 and 32) were significantly decreased in the AN-R group in comparison with that in the HV (p < 0.05) (Figure 1). In particular, in cingulate, insula and secondary somatosensory cortex, signals from brain stem and hypothalamus in addition to direct sensory signals from the organism are more refined and probably accessible to consciousness [10]. That is because blood-flow changes in most subdivisions of the frontal cortex occurred more often in PET study subtractions that also showed changes in the anterior cingulate gyri [14]. www.biomedcentral.com /1471-244X/1/2   (2484 words)
