“…One hypothesis for this functional reorganization would be that, like attentional processes, the IPC may be more implicated in controlled processes while the posterior regions may be more related to automatic processes (Lezak, Howieson, & Loring, 2004). Considering that automatic processes are more resistant to normal aging (Grieder, et al, 2012;Wlotko, Lee, & Federmeier, 2010) than controlled processes, older adults might rely more on posterior regions to complete a semantic judgment task. Nonetheless, when task demands are too important, for instance when abstract words have to be processed, older adults can recruit the IPC to a greater extent, in order to maintain a high-level performance.…”

Semantic memory recruits an extensive neural network including the left inferior prefrontal cortex (IPC) and the left temporoparietal region, which are involved in semantic control processes, as well as the anterior temporal lobe region (ATL) which is considered to be involved in processing semantic information at a central level. However, little is known about the underlying neuronal integrity of the semantic network in normal aging. Young and older healthy adults carried out a semantic judgment task while their cortical activity was recorded using magnetoencephalography (MEG). Despite equivalent behavioral performance, young adults activated the left IPC to a greater extent than older adults, while the latter group recruited the temporoparietal region bilaterally and the left ATL to a greater extent than younger adults. Results indicate that significant neuronal changes occur in normal aging, mainly in regions underlying semantic control processes, despite an apparent stability in performance at the behavioral level.

“…4). While early studies described this ERP component as a marker of syntactic violation (Friederici and Meyer, 2004), recent studies challenged this interpretation by showing LPC in response to semantic violations or anomalies in the absence of any syntactic violation (Grieder et al, 2012;Hill et al, 2002). In addition, a LPC could be recorded in response to various manipulations of verbal semantics such as inversion of causality (e.g.…”

Electroencephalography (EEG) is an established measure in the field of brain resting state with a range of quantitative methods (qEEG) that yield unique information about neuronal activation and synchronization. Meanwhile, in the last decade, functional magnetic resonance imaging (fMRI) studies have revealed the existence of more than a dozen resting state networks (RSNs), and combined qEEG and fMRI have allowed us to gain understanding about the relationship of qEEG and fMRI-RSNs. However, the overall picture is less clear because there is no a priori hypothesis about which EEG features correspond well to fMRI-RSNs. We reviewed the associations of several types of qEEG features to four RSNs considered as neurocognitive systems central for higher brain processes: the default mode network, dorsal and ventral frontoparietal networks, and the salience network. We could identify 12 papers correlating qEEG and RSNs in adult human subjects and employing a simultaneous design under a no-task resting state condition. A systematic overview investigates which qEEG features replicably relate to the chosen RSNs. This review article leads to the conclusion that spatially delimited θ and whole/local α may be the most promising measures, but the time domain methods add important additional information.
