“…MacPherson (2002) suggested that the dorsolateral PFC undergoes more extensive changes than the ventromedial PFC, although there is little direct evidence from neuroimaging studies for this distinction (Raz et al, 1997;Salat et al, 2001;Tisserand et al, 2002). Although the conclusions about brain location on the basis of behavioral data alone are limited and speculative, the combined age-related inhibition and task management changes observed in the present study would be consistent with dorsolateral PFC mechanisms, but would also be consistent with a possible involvement of the anterior cingulate cortex (Cummings, 1993;Dreher & Grafman, 2003;Loose et al, 2003;Sturm & Zimmermann, 2000;Suchan et al, 2003Suchan et al, , 2005. This is also supported by neuroimaging results of decreased rCBF within the frontal cingular gyri in older subjects (Larsson et al, 2001).…”

Normal aging has been associated with executive control deficits, but it is as yet unclear whether different executive subprocesses are differentially affected during the course of aging. The present study aimed to investigate age effects on a range of executive control subcomponents. Four consecutive age groups (20-30 years, 31-45 years, 46-60 years, 61-75 years), matched on present state IQ and mood, were compared on tasks of strategic memory processing, verbal fluency, reasoning, inhibition, task management, and self-rating of executive abilities. Deficits concerning the suppression of habitual and experimentally induced prepotent response tendencies and the ability to efficiently divide attention were observed in subjects over 60 years of age compared to the younger groups, while memory, verbal fluency, and reasoning were largely unaffected. Results suggest a sharp decline of executive function after age 60 and a differential course of different executive subcomponents across aging, adding further support to a multi-dimensional model of executive function.

“…Adults, by contrast, did show an MMN with delays that long (Brinkman & Stauder, 2008). The ability to maintain a schema in working memory during the delay between a comparison and test event is still maturing at 12 to 15 years (Suchan, Pickenhagen, & Daum, 2005).…”

The concept of novelty has acquired a large number of diverse referents over the past quarter-century as a result of new methods that permit measurement of a variety of biological and behavioral reactions to novel incentives in both humans and animals. As a result, the term has acquired varied meanings. This analysis of novelty makes four claims. First, the specific state of uncertainty that a novel event creates depends on its origin. Second, unexpected events that alter the immediate stimulus surround (called stimulus novelty) should be distinguished from those that are inconsistent with an agent's long term knowledge (called conceptual novelty). Third, the critical features that render an event novel can vary with the agent's intention to classify or to act on an object and the balance between these two frames changes with development. Finally, the state of uncertainty created when an agent must choose one response from two or more alternatives differs from the states provoked by stimulus and conceptual novelty.

Background: Apolipoprotein E (APOE) ε4 is the only established risk gene for lateonset, sporadic Alzheimer's disease (AD). Previous studies have provided inconsistent evidence for the effect of APOE ε4 status on the visuospatial working memory (VSWM).Objective: The aim was to investigate the effect of APOE ε4 on VSWM with an event-related potential (ERP) study in healthy controls (HC) and amnestic mild cognitive impairment (aMCI) patients. Methods:The study recorded 39 aMCI patients (27 APOE ε4 non-carriers and 12 APOE ε4 carriers) and their 43 matched controls (25 APOE ε4 non-carriers and 18 APOE ε4 carriers) with an 64-channel electroencephalogram. Participants performed an N-back task, a VSWM paradigm that manipulated the number of items to be stored in memory.Results: The present study detected reduced accuracy and delayed mean correct response time (RT) in aMCI patients compared to HC. P300, a positive component that peaks between 300 and 500 ms, was elicited by the VSWM task. In addition, aMCI patients showed decreased P300 amplitude at the central-parietal (CP1, CPz, and CP2) and parietal (P1, Pz, and P2) electrodes in 0-and 1-back task compared to HC. In both HC and aMCI patients, APOE ε4 carriers showed reduced P300 amplitude with respect to non-carriers, whereas no significant differences in accuracy or RT were detected between APOE ε4 carriers and non-carriers. Additionally, standardized lowresolution brain electromagnetic tomography analysis (s-LORETA) showed enhanced brain activation in the right parahippocampal gyrus (PHG) during P300 time range in APOE ε4 carriers with respect to non-carriers in aMCI patients.Conclusion: It demonstrated that P300 amplitude could predict VSWM deficits in aMCI patients and contribute to early detection of VSWM deficits in APOE ε4 carriers.
