“…However, there was no overlap with the cluster (MNI coordinates: 30 45 4) previously identified by the correlational analysis between variations of SRE performance and grey matter density in AD patients (Genon et al, in press). In addition, the functional brain network related to self-appraisal included activation of orbitofrontal regions which might be related to the engagement of emotional and decision making processes (Volz and von Cramon, 2009), activation of the lateral temporal cortex which might support retrieval of semantic representations (Rogers et al, 2006) and activation of the superior parietal cortex which may reflect the involvement of either attentional (Cabeza et al, 2011) or memory retrieval processes (Kim, 2010).…”

“…The left inferior frontal gyrus, pars opercularis (IFGo; containing Broca's area) seed anchored bilateral IFGo and ipsilateral dorsal anterior insula covariance in group 1, which expanded to include bilateral dorsal anterior insulae in group 2, expanded further to include dorsolateral prefrontal cortex in group 3, and expanded further still to include more extensive frontal regions, posterior superior temporal gyrus (Wernicke's area), and frontoparietal sensorimotor and cingulate motor areas in group 4. A left temporal pole seed, chosen to map a network related to semantic knowledge (37,38), covaried in group 1 with ipsilateral amygdala, contralateral temporal pole, and bilateral inferior temporal cortex. This pattern expanded to include bilateral insular regions in group 2 and contralateral amygdala, anterior cingulate, medial and lateral orbitofrontal, and frontopolar regions in group 3.…”

Intrinsic or resting state functional connectivity MRI and structural covariance MRI have begun to reveal the adult human brain's multiple network architectures. How and when these networks emerge during development remains unclear, but understanding ontogeny could shed light on network function and dysfunction. In this study, we applied structural covariance MRI techniques to 300 children in four age categories (early childhood, 5-8 y; late childhood, 8.5-11 y; early adolescence, 12-14 y; late adolescence, 16-18 y) to characterize gray matter structural relationships between cortical nodes that make up large-scale functional networks. Network nodes identified from eight widely replicated functional intrinsic connectivity networks served as seed regions to map whole-brain structural covariance patterns in each age group. In general, structural covariance in the youngest age group was limited to seed and contralateral homologous regions. Networks derived using primary sensory and motor cortex seeds were already well-developed in early childhood but expanded in early adolescence before pruning to a more restricted topology resembling adult intrinsic connectivity network patterns. In contrast, language, social-emotional, and other cognitive networks were relatively undeveloped in younger age groups and showed increasingly distributed topology in older children. The so-called default-mode network provided a notable exception, following a developmental trajectory more similar to the primary sensorimotor systems. Relationships between functional maturation and structural covariance networks topology warrant future exploration.childhood | children | connectivity | development | neuroimaging

“…Other studies using semantic dementia patients commonly reported lesions in the anterior temporal lobe (Davies et al, 2004;Nestor et al, 2006). Neuroimaging studies also revealed that the anterior temporal regions are commonly activated during psychological tasks requiring various categories of semantic memory (Devlin et al, 2000;Bright et al, 2004;Rogers et al, 2006).…”

Retrieval of remote memory is considered to differentially involve the anterior and posterior temporal neocortices. Previous neuropsychological studies suggest that the different posterior temporal cortical regions are involved in the retrieval of remote memory of different categories of stimuli, whereas the anterior region is involved more generally in remote memory retrieval. In the present study, using functional magnetic resonance imaging of human brains, we tested this dissociation by examining the more precise characteristics of the anterior and posterior temporal cortical regions. Two categories of stimuli, faces and scenes, were used for paired stimuli to be retrieved, and the brain activity during retrieval of paired stimuli that were learned immediately before the scanning was compared with that during retrieval of paired stimuli that were learned ϳ8 weeks earlier. We found that the different posterior temporal cortical regions were activated during retrieval of different categories of remote memory in a category-specific manner, whereas the anterior temporal cortical region was activated during retrieval of remote memory in a category-general manner. Furthermore, by applying a multivariate pattern analysis to psychophysiological interactions during retrieval of remote memory relative to recent memory, we revealed the significant interaction from the category-specific posterior temporal cortical regions to the category-general anterior temporal region. These results suggest that the posterior temporal cortical regions are involved in representation and retrieval of category-specific remote memory, whereas the anterior cortical temporal region is involved in category-general retrieval process of remote memory.
