“…2), suggesting that our observations might be the product of sources in orbitofrontal cortex . However, the exact sources remain speculative due to the low number of electrodes included in the current study and the fact that the scalp distribution does not necessarily reflect the exact location of its underlying sources (Guillem et al, 2001;Potts and Tucker, 2001). Recently, for instance, P2a was linked to sources in medial prefrontal cortex (Potts et al, 2006).…”

“…This ERP component is commonly observed in tasks using visual stimuli, but its functional significance is subject of debate (Luck and Hillyard, 1994;Makeig et al, 1999;Guillem et al, 2001;Potts and Tucker, 2001;Potts, 2004). P2a is generally present in response to targets or task-relevant stimuli and is most consistently interpreted as indexing operations related to the task-relevance of the stimulus (Guillem et al, 2001;Potts and Tucker, 2001;Potts, 2004).…”

Methods: Twenty-three 17 year old boys of mothers whose level of anxiety was measured during pregnancy were investigated using ERP while performing a Go/Nogo paradigm assessing exogenous cognitive control and a Gambling paradigm requiring endogenous cognitive control. Results: No effects of antenatal maternal anxiety were observed in the Go/Nogo paradigm. However, in the Gambling paradigm adolescents of the high anxiety group (n = 8) showed a less efficient pattern of decision making compared to the adolescents in the low-average anxiety group (n = 15). Moreover, only for this task the ERP data showed an enlarged early frontal P2a component in the high anxiety group. Conclusions: The brain activity of adolescents during an endogenous cognitive control task is associated to the level of anxiety experienced by their mother during pregnancy. This association was not observed during an exogenous cognitive control task. Significance: This study indicates that a child's brain functionality is related to its mother's anxiety during pregnancy. Endogenous cognitive control is regarded the cognitive function most affected by the level of antenatal maternal anxiety.

“…Thus, the FP effect may depend more on the type of information retrieved than on the recognition processes implemented. This frontal ERP effect have been described during unfamiliar faces recognition [32]. On the other hand, the FC effect has been described in memory exclusion task [63].…”

“…This late positive component observed principally on the right fronto-central regions is particularly evident in tasks involving source retrieval [64]. It is thus thought to reflect strategic memory processes [2] or more specifically the goal-directed integration of the intrinsic attributes of items [32]. Two sources of evidence can be brought to bear on the question of the origin of this effect, which converge to suggest that it reflects neural activity originating from right prefrontal cortex [23].…”

“…The type of context to be retrieved and its relation with the target appear to be another critical variable for proposing a functional interpretation of the observed effects [see also [32]]. This would seem to imply that recognition is not uniform from the functional and neurophysiological standpoints and probably accounts for the observed discrepancies between the different functional interpretations.…”

Behavioural and electrophysiological effects of visual paired associate context manipulations during encoding and recognition in younger adults, older adults and older cognitively declined adults

The current study examined the EEG of young, old and old declined adults performing a visual paired associate task. In order to examine the effects of encoding context and stimulus repetition, target pairs were presented on either detailed or white backgrounds and were repeatedly presented during both early and late phases of encoding. Results indicated an increase in P300 amplitude in the right parietal cortex from early to late stages of encoding in older declined adults, whereas both younger adults and older controls showed a reduction in P300 amplitude in this same area from early to late phase encoding. In the right hemisphere, stimuli encoded with a white background had larger P300 amplitudes than stimuli presented with a detailed background; however, in the left hemisphere, in the later stages of encoding, stimuli presented with a detailed background had larger amplitudes than stimuli presented with a white background. Behaviourally, there was better memory for congruent stimuli reinstated with a detailed background, but this finding was for older controls only. During recognition, there was a general trend for congruent stimuli to elicit a larger amplitude response than incongruent stimuli, suggesting a distinct effect of context reinstatement on underlying patterns of physiological responding. However, behavioural data suggest that older declined adults showed no memory benefits associated with context reinstatement. When compared with older declined adults, younger adults had larger P100 amplitude responses to stimuli presented during recognition, and overall, younger adults had faster recognition reaction times than older control and older declined adults. Further analysis of repetition effects and context-based hemispheric asymmetry may prove informative in identifying declining memory performance in the elderly, potentially before it becomes manifested behaviourally.
