• The parahippocampal gyrus (or hippocampal gyrus) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. (wikipedia.org)
  • Contributions from the anterior cingulate, orbitofrontal, medial and lateral prefrontal cortices, and insular cortex connect with limbic structures within the temporal lobes such as the amygdala, hippocampus, and parahippocampal gyrus to integrate multiple brain processes needed to plan and organize goal-directed behavior, as well as attach emotional valence to memory.

  • hypothesized that memory function is associated with the pyramidal and granule cells located in the dentate gyrus of the hippocampus [ 6 ]. (hindawi.com)
  • We directly recorded the responses of individual neurons during flash suppression in the human amygdala, entorhinal cortex, hippocampus, and parahippocampal gyrus, allowing us to explore the neuronal responses in untrained subjects at a high spatial and temporal resolution in the medial temporal lobe.

  • When processing facial expressions of emotions, both patients with schizophrenia and healthy controls activated the bilateral amygdala and right fusiform gyri. (nih.gov)
  • When directly compared with controls, the extent of activation in bilateral amygdala, parahippocampal gyrus and fusiform gyrus, right superior frontal gyrus, and lentiform nucleus was significantly less in patients. (nih.gov)
  • The term parahippocampal cortex is used to refer to an area that encompasses both the posterior parahippocampal gyrus and the medial portion of the fusiform gyrus[citation needed]. (wikipedia.org)
  • An earlier report from our laboratory demonstrated that there were sex differences in the dendritic tree of granule neurons from the rat dentate gyrus (Juraska, Fitch, Henderson, & Rivers, 1985). (illinois.edu)
  • We found that urban upbringing and BDNF genotype interacted to alter activation in areas in the bilateral parahippocampal gyrus, whereby urban Met/Met carriers activated the least. (nih.gov)
  • Discussion: As was seen with the COMT gene, the BDNF-by-Urbanicity interaction yielded greatest activation in bilateral parahippocampal gyrus for carriers of the risk allele. (nih.gov)
  • Signal weakened regions could be found when needling at all the three points, the commonly activated regions were bilateral parahippocampal, hippocampal, callosal gyrus, bilateral praecuneus and cerebellum. (acupuncture.com)

  • Our data show a robust reduction of cortical thickness in the left parahippocampal gyrus (PHG) in G allele homozygotes of GAD1 rs3749034. (nih.gov)
  • The findings appeared robust, replicating across paired frontal and temporal cortical samples from 113 ROSMAP brains, as well as in 151 parahippocampal gyrus tissues from the Mount Sinai Brain Bank and 40 DLPFC and anterior cingulate samples from the Emory Brain Bank. (alzforum.org)
  • Investigations of memory in rats and nonhuman primates have demonstrated functional specialization within the medial temporal lobe (MTL), a set of heavily interconnected structures including the hippocampal formation and underlying entorhinal, perirhinal, and parahippocampal cortices. (jneurosci.org)
  • The parahippocampal place area (PPA) is a sub-region of the parahippocampal cortex that lies medially in the inferior temporo-occipital cortex. (wikipedia.org)
  • RESULTS: The commonly activated regions were postcentral gyrus and right inferior frontal gyrus when needling at ST36 and SP6, and the different activated areas included left inferior frontal gyrus, left insula, left inferior parietal lobule, left culmen, left middle temporal gyrus and left middle frontal gyrus, while no cortical signal enhanced region was found when needling at GB34.

  • The anterior part of the gyrus includes the perirhinal and entorhinal cortices[citation needed]. (wikipedia.org)
  • We found a COMT-by-urbanicity interaction whereby carriers of the risk allele, Val/Val showed more parahippocampal gyrus activation during an encoding task when raised exclusively in an urban environment. (nih.gov)
  • This produces brain activity markedly different from imaging playing tennis, with significant blood flow to the parahippocampal gyrus and other parts of the brain. (nationalrighttolifenews.org)
  • For example, Rankin's research suggests that the right parahippocampal gyrus enables people to detect sarcasm. (wikipedia.org)
  • Individual difference analyses also found the magnitude of parahippocampal activation following gameplay onset to correlate with positive attitudes toward chemotherapy assessed both at the end of the scanning session and at an unannounced one-month follow-up. (ucla.edu)
